Square Well Deep Well Plates

<h2 data-section-id="7nn2n" data-start="0" data-end="42">What Are Square Well Deep Well Plates?</h2>
&nbsp;
Square well deep well plates are polypropylene microplates designed with square-shaped wells instead of traditional round wells. This design maximizes liquid capacity within the standard SBS/ANSI microplate footprint, making them ideal for high-throughput laboratory workflows that require larger sample volumes. Commonly available in 96-well formats with capacities ranging from 1.1 mL to 2.2 mL per well, these plates are widely used for nucleic acid extraction, protein precipitation, compound library storage, sample preparation, and automated liquid handling.
The square-well geometry increases usable volume while maintaining compatibility with automated platforms from Hamilton, Tecan, Beckman Coulter, and Agilent. Manufactured from virgin polypropylene, square well plates offer excellent chemical resistance to DMSO, ethanol, acetonitrile, and extraction buffers, while minimizing sample binding and contamination risks.

<h2 data-section-id="1lthnju" data-start="1133" data-end="1179">How to Choose Square Well Deep Well Plates</h2>
&nbsp;
Well Volume The most common formats are 2.0 mL and 2.2 mL square well plates, which provide sufficient volume for nucleic acid extraction, protein precipitation, and compound storage workflows. Lower-profile 1.1 mL plates are useful when deck height limitations or freezer space optimization are important considerations.
Bottom Geometry V-bottom wells concentrate liquid and pellets into a single point, enabling more complete aspiration and improved recovery during centrifugation-based workflows. U-bottom wells promote better mixing and resuspension, making them suitable for microbial culture applications and serial dilutions.
Centrifugation Requirements Most square well polypropylene plates are compatible with centrifugation speeds between 4,000 &times; g and 6,000 &times; g. For demanding extraction protocols, reinforced plate designs provide additional structural stability during high-speed centrifugation.
Automation Compatibility Select plates that comply with ANSI/SLAS standards and include molded alphanumeric indexing for sample tracking. Features such as stacking lugs and raised well rims improve robotic handling and sealing performance.
Certification Standards For molecular biology applications, choose plates manufactured from virgin polypropylene and certified DNase-free, RNase-free, DNA-free, and PCR inhibitor-free. Sterile options are recommended for sensitive workflows and regulated environments.

<h2 data-section-id="m2xmka" data-start="1392" data-end="1436">How to Choose Round Well Deep Well Plates</h2>
&nbsp;
Well Volume
The 1.2 mL round well plate is specified for smaller-input nucleic acid extraction protocols (blood, plasma, swab) and fits automated deck formats with restricted Z-height clearance. The 2.0 mL round well format accommodates larger sample input volumes for high-yield extractions and is the standard format for Nest Scientific deep well plates used in nucleic acid processing. Confirm working volume versus total well volume in the product specification &mdash; a 2.0 mL plate typically has a total volume of 2,200&ndash;2,400 &micro;L.
Bottom Geometry
U-bottom (hemispherical) round wells are standard for sample storage, bacterial and cell culture, and general liquid handling where complete aspiration is not required. V-bottom (conical) round wells concentrate liquid and pellet to the lowest point for complete aspiration and enhanced pellet recovery, preferred in enzymatic assay and precipitation protocols. Flat-bottom round well plates are used when an optical flat surface is needed for absorbance-based assay measurement.
Sterility Requirements
Non-sterile round well deep well plates manufactured in ISO 8 cleanrooms satisfy most nucleic acid extraction and sample processing workflows. Sterile options (gamma-irradiated, SAL 10⁻⁶) are required for cell culture, bacterial culture, and RNA extraction from live cells. Autoclavable polypropylene formats provide a cost-effective reusable sterile option for labs with autoclave access.
Centrifugation and Sealing
Standard round well deep well plates are rated 4,000&ndash;6,000 &times; g. Raised well rims ensure consistent sealing with adhesive films, heat-seal foils, and pre-slit silicone mats. Nest Scientific 96-well round well silicone sealing mats (pre-slit, 7 mm diameter) are compatible with 0.35&ndash;1.35 mL round well plates.
Automation Compatibility
Specify virgin polypropylene, lot-certified DNase-free, RNase-free, DNA-free, and PCR inhibitor-free for nucleic acid extraction. Nest Scientific deep well plates use USP Class VI polypropylene material with high chemical stability for demanding extraction workflows.
&nbsp;
<h2 data-section-id="1jl751w" data-start="4818" data-end="4843">Specifications Context</h2>

Centrifuge Tubes

<h2>What Are Centrifuge Tubes?</h2>
 Centrifuge tubes are cylindrical laboratory containers with caps that are used to separate, pellet, and store biological or chemical samples through centrifugal force. They are commonly made from polypropylene (PP) or polystyrene (PS) and are available in sizes ranging from small 0.5 mL microtubes to larger 50 mL conical tubes. These tubes are widely used for cell pelleting, protein precipitation, DNA and RNA extraction, tissue homogenate clarification, and long-term sample storage. Depending on the material, they can withstand temperatures from &minus;80 &deg;C to +121 &deg;C.
In short, the best centrifuge tube depends on your centrifuge rotor, required g-force, sample volume, and sterility needs.

<h2>How to Choose Centrifuge Tubes</h2>
 Volume and Rotor Compatibility
Select a tube size that matches both your sample volume and centrifuge rotor. Microtubes ranging from 0.5&ndash;2 mL are commonly used in microcentrifuges and can typically handle speeds up to 20,000 &times; g. Midi tubes in the 5&ndash;10 mL range are suitable for intermediate sample volumes, while 15 mL and 50 mL conical tubes are commonly used in clinical, research, and preparative centrifuges.
Material: Polypropylene vs. Polystyrene
Polypropylene (PP) tubes offer excellent chemical resistance and can tolerate temperatures from &minus;80 &deg;C to +121 &deg;C. They are suitable for autoclaving and exposure to many laboratory solvents. Polystyrene (PS) tubes provide superior optical clarity, making it easier to visually inspect samples and liquid levels, but they have lower resistance to solvents and extreme temperatures.
Sterility and Contamination Control
Sterile centrifuge tubes are typically gamma- or E-beam-irradiated and certified free of RNase, DNase, and pyrogens. These tubes are recommended for RNA extraction, cell culture, and clinical applications where contamination must be minimized. Non-sterile tubes may still be RNase- and DNase-free and are often suitable for routine DNA work and general sample storage.
Cap Design
Attached screw caps help prevent cap mix-ups and sample contamination, especially in high-throughput laboratories. Separate caps can be quicker to open and may be preferred in workflows that require frequent access to samples. If tubes will be used with automated systems, cap dimensions should be verified for compatibility with liquid handling equipment.
Packaging Options
Racked tubes provide convenient organization and allow direct pipetting while the tubes remain in the rack. Bulk-bagged tubes offer a more economical option for laboratories that process large volumes of samples and already have tube storage systems in place.
<h2> Comparing Common Centrifuge Tube Types</h2>
 Microtubes (0.5&ndash;2 mL) are ideal for PCR preparation, microcentrifuge applications, and storage of small sample volumes. They can generally withstand centrifugal forces up to 20,000 &times; g.
Midi tubes (5&ndash;10 mL) are designed for intermediate sample volumes such as culture supernatants and can typically tolerate forces up to 16,000 &times; g.
Sterile 15 mL conical tubes are frequently used for cell pelleting, RNA extraction, and clinical sample processing, with typical ratings between 12,000 and 15,000 &times; g.
Sterile 50 mL conical tubes are commonly selected for larger-volume applications including tissue culture work, density gradient preparation, and large-scale sample processing.
Polystyrene conical tubes in 15 mL and 50 mL formats are often chosen when visual sample inspection is important and solvent exposure is minimal.
<h2> Specifications and Features</h2>
 Polypropylene centrifuge tubes from Globe Scientific and Nest Scientific are manufactured from USP Class VI virgin resin and do not contain plasticizers or processing additives. Sterile products are typically irradiated to achieve a sterility assurance level (SAL) of 10⁻⁶. Most 15 mL tubes feature graduation marks at 1 mL intervals, while 50 mL tubes are usually graduated every 5 mL. MBP offers both bagged and racked centrifuge tube formats, including 15 mL and 50 mL conical tubes as well as smaller microtube and midi tube options.

&nbsp;
Volume: 0.5 mL / 1.5 mL / 2.0 mL
&nbsp;0.5 mL tubes minimize dead volume for concentrated or precious samples and fit compact block heaters. 1.5 mL is the universal format compatible with virtually all microcentrifuge rotors, heating blocks, and automated liquid handlers. 2.0 mL provides extra headspace for vortex mixing and bead-based extraction protocols; the slightly wider diameter is also compatible with most 1.5 mL rotor slots.
Cap Style: Snap Cap vs Screw Cap
Snap-cap microcentrifuge tubes feature hinged lids that allow quick one-handed operation and are preferred for high-throughput laboratory workflows involving frequent pipetting.
Screw-cap tubes equipped with O-rings or sealing rings provide a hermetic seal capable of withstanding centrifugal forces up to 20,000 &times; g. These tubes are recommended for volatile reagents, repeated freeze-thaw cycles, and long-term storage at ultra-low temperatures. Laboratories requiring enhanced sample security often select screw-cap formats for valuable or irreplaceable specimens.
Standard vs Low-Binding Polypropylene
Standard polypropylene microcentrifuge tubes are suitable for most routine laboratory applications. Low-binding polypropylene tubes are designed to reduce sample adsorption to tube walls and are particularly beneficial when working with dilute proteins, low-concentration nucleic acids, or single-cell samples where maximizing recovery is critical.
Bottom Geometry: Conical vs Self-Standing
Conical-bottom tubes concentrate pellets at the tip of the tube, improving sample recovery and simplifying resuspension after centrifugation.
Self-standing tubes feature a flat base that allows them to remain upright without a rack, making them convenient for sample handling, labeling, and storage. While they offer greater bench-top convenience, pellets may form slightly off-center compared with traditional conical-bottom designs.

<h2 data-section-id="1j0vxh6" data-start="772" data-end="821">How to Choose 15 mL and 50 mL Centrifuge Tubes</h2>
&nbsp;
Material: PP vs PS
Polypropylene tubes (Globe Scientific, Nest Scientific) are resistant to most organic solvents, stable from &minus;80 &deg;C to +121 &deg;C, and autoclavable. Polystyrene tubes offer greater optical clarity &mdash; the tube wall is transparent enough to read the sample meniscus and assess pellet quality without removing the tube from the rack. Choose PS when visual inspection is a workflow step; choose PP for all other applications.
Sterility Grade
Sterile tubes (gamma- or E-beam-irradiated, RNase-free, DNase-free, non-pyrogenic) are required for RNA work, primary cell culture, and clinical sample handling. Non-sterile, DNase/RNase-free tubes are appropriate and more cost-effective for DNA extractions, protein assays, and general preparative spins.
Cap Style: Flat-Top vs Plug-Seal
Flat-top screw caps (high-density polyethylene, HDPE) provide a flat writing surface for sample labeling and a double-threaded design that reduces cross-threading in high-throughput workflows. Plug-seal screw caps (HDPE or PP) create a secondary internal seal for leak-prone applications. Attached caps come pre-assembled on sterile tubes; separate caps are standard on non-sterile tubes.
Pack Format: Racked vs Bagged
Racked tubes (foam or PS rack, 50 &times; 15 mL or 25 &times; 50 mL per rack, 500 per case) allow direct pipetting without removing tubes and enable viewing of graduations without disturbing the rack. Bagged tubes (25 or 50 per bag, 500 per case) offer a lower cost per tube and suit labs with robotic liquid handlers or in-house racking systems.

<h2 data-path-to-node="1"> What Are PCR Tube Racks?</h2>
 PCR tube racks are polypropylene holders that maintain 0.2 mL PCR tubes and strip tubes in a stable 8&times;12 (96-position) upright array during reaction setup, pre-PCR storage, and post-amplification handling. They stabilise tubes during multichannel pipetting, prevent tip deflection when dispensing with an 8-channel pipette, and serve as organisational tools for pre- and post-PCR sample management. Most racks accept both individual 0.2 mL tubes and 8-strip or 12-strip tubes in the same 96-well footprint.&nbsp;

 Well Diameter and Tube Compatibility Standard 96-well PCR racks have a 5.2 mm well diameter, compatible with most 0.2 mL thin-wall PCR tubes from Globe Scientific, Nest Scientific, Axygen/Corning, Eppendorf, and equivalent brands. Confirm the collar diameter of your specific tube brand before ordering if using non-standard tube geometry. Lid: Hinged Flat vs Translucent Cover vs No Lid Hinged flat lids lie flush when open for unobstructed pipette access; the lid can be closed to protect tubes during incubation or transport. Translucent polycarbonate lids allow visual sample inspection without lid removal &mdash; useful for barcode readers that scan through the cover. Lidless racks are the simplest format for bench use, where brief sample exposure is acceptable. Colour Coding Racks are available in single colours (blue, green, pink, yellow, orange) and assorted multi-colour packs. Colour-coded racks help segregate pre-PCR and post-PCR samples, reducing cross-contamination risk in labs without fully separated pre/post-PCR workspaces. Autoclavability Polypropylene PCR tube racks are autoclavable at 121&deg;C (250&deg;F) for sterilisation between use cycles. Polycarbonate lids withstand repeated autoclave cycles at standard sterilisation conditions. SBS Footprint for Automation Select PCR strip racks with an SBS/SLAS-compliant footprint (127.76 &times; 85.47 mm) to enable use with robotic liquid handlers and automated workstations when processing strip tubes on automation platforms.

<h2 dir="ltr"> What Are 8-Strip PCR Tubes?</h2>
 8-strip PCR tubes are a connected row of eight individual thin-wall polypropylene tubes supplied as a single unit, designed for simultaneous processing of eight reactions per strip. The strip format accommodates multichannel pipettes at standard 9 mm well spacing, reducing setup time compared to handling individual tubes one at a time. Available in 0.2 mL for standard thermal cycler blocks and 0.1 mL for fast-block or low-profile instruments. Caps are available attached (dome or flat) or as separate cap strips for labs that prefer independent tube and cap management. 8-strip tubes are the most efficient manual format for 8- or 16-sample PCR batches &mdash; choose 0.2 mL for standard blocks, 0.1 mL for fast-block cyclers.

 Volume: 0.2 mL vs 0.1 mL Standard 0.2 mL strips fit conventional tall-block cyclers, including Bio-Rad T100, Eppendorf Mastercycler, and Applied Biosystems Veriti. Low-profile 0.1 mL strips are required for fast-block instruments such as the Applied Biosystems StepOnePlus, Bio-Rad CFX96 Fast, and Roche LightCycler 480, where the shallower well reduces thermal equilibration time and supports faster cycling protocols. Cap Style: Dome vs Flat, Optical vs Separate Cap Strip Attached dome caps are the standard choice for endpoint PCR, where no fluorescence is read through the cap lid. Flat optically clear attached caps &mdash; or separately purchased optical cap strips &mdash; are required for real-time qPCR when detection occurs through the top of the tube; dome caps attenuate fluorescence and compromise Ct consistency. Separate cap strips offer flexibility to mix dome and flat caps on the same strip. Attached vs Separate Caps Attached caps prevent cap mix-ups and reduce handling steps in high-throughput setups. Separate cap strips (tube strip + cap strip sold together in the same bag) allow independent tube loading and cap seating &mdash; preferred when using automated liquid handlers or when labelling the cap exterior is important. Colour Options Clear strips are standard; assorted colour packs (clear, red, yellow, blue, green) allow colour-coded sample tracking. White polypropylene strips increase qPCR fluorescence signal in bottom-read optical configurations by reflecting emission back through the detector. Strip Rigidity Split-apart strips (perforated between tubes) allow individual tubes to be broken off from the strip &mdash; useful when fewer than 8 reactions are needed and waste reduction matters. 
<h2 dir="ltr"> Specifications Context</h2>
 8-strip tube walls are typically 0.25&ndash;0.35 mm thick virgin polypropylene free of additives, antistatic agents, and dyes. Certified DNase-free, RNase-free, human DNA-free, and PCR inhibitor-free per independent lot testing. Standard packs contain 120 strips (960 reactions) for 0.2 mL format; 0.1 mL packs are often 120 strips as well.

<h2 data-section-id="144nuix" data-start="0" data-end="40">What Are KingFisher Flex Consumables?</h2>
&nbsp;
KingFisher Flex consumables are specialized plates, tip combs, and accessories designed specifically for Thermo Scientific KingFisher magnetic particle processors, including the KingFisher Flex, Apex, Duo Prime, and Presto systems. These consumables are engineered to support automated magnetic bead-based purification workflows for DNA extraction, RNA isolation, protein purification, cell isolation, and other molecular biology applications. Their precise dimensions and well geometries ensure accurate magnetic rod movement, efficient bead transfer, and consistent purification results across high-throughput laboratory workflows.
Unlike standard deep well plates, KingFisher consumables are manufactured from low-binding polypropylene to minimize the loss of nucleic acids and proteins during extraction and washing steps. This helps maximize sample recovery, improve purity, and maintain reproducibility in research, clinical diagnostics, biobanking, and next-generation sequencing (NGS) applications.

<h2 data-section-id="1h779p8" data-start="1262" data-end="1306">How to Choose KingFisher Flex Consumables</h2>
&nbsp;
Instrument Configuration
Consumable selection depends on the instrument model and processing head installed. Most KingFisher Flex systems use a 96-well head designed for medium-throughput sample processing, while certain applications require a 24-well head for larger sample volumes. Always verify your instrument configuration before ordering consumables.
Sample Volume Requirements
The 96-well format is ideal for routine DNA and RNA extraction from blood, plasma, swabs, tissue lysates, and cultured cells. Applications requiring larger input volumes, such as circulating cell-free DNA isolation, environmental testing, or stool sample processing, often use the 24-well format, which accommodates significantly larger volumes per well.
Sterility Requirements
Non-sterile consumables are commonly used for standard nucleic acid purification and protein extraction workflows. Sterile plates and sterile plate-tip comb combination packs are recommended for cell-based applications, sensitive RNA workflows, and any procedure requiring aseptic processing conditions.
Individual Components vs. Combination Packs
Many laboratories purchase plates and tip combs separately to match workflow requirements. Combination packs containing both sterile plates and matching sterile tip combs simplify inventory management and ensure compatibility between components.
Downstream Application
For PCR, qPCR, sequencing, and library preparation workflows, purified samples are typically transferred into 96-well microplates with smaller working volumes. Applications requiring larger elution volumes may use deep well plates for the final collection step.
&nbsp;
<h2 data-section-id="1jl751w" data-start="3463" data-end="3488">Specifications Context</h2>
&nbsp;
KingFisher consumables are manufactured from high-purity, low-binding polypropylene to reduce non-specific adsorption of DNA, RNA, proteins, and magnetic beads. They are produced under strict quality control standards to ensure dimensional consistency and compatibility with automated magnetic particle processors.
These consumables are widely used in molecular diagnostics, genomics, biobanking, pharmaceutical research, and clinical laboratories. Their standardized design supports reproducible extraction performance while maintaining compatibility with automated sample preparation workflows.
For laboratories requiring more general automation-compatible sample processing plates, deep well plates provide SBS-format compatibility with liquid handling systems from Hamilton, Tecan, Beckman Coulter, and other automation platforms. Immunoassay and ELISA workflows, however, require specialized assay plates designed for optical detection rather than magnetic bead processing.&nbsp;

Automation Consumables

<h2 dir="ltr"> What Are Automation Consumables?</h2>
 Automation consumables are plasticware items engineered to the tight tolerances required for consistent, unattended operation on robotic liquid-handling systems. Unlike manual-use consumables, automation consumables require tighter moulding tolerances, consistent tip-collar geometry for reproducible robotic tip pick-up and ejection, and barcode compatibility for LIMS-integrated workflows. Automation consumables are not interchangeable with manual-use plasticware &mdash; tip geometry and dimensional tolerance requirements differ, and substituting manual tips in robotic tip seats causes pick-up failures and run aborts.

Instrument-Specific vs Universal Robotic Tips Robotic pipette tips are typically instrument-specific: Hamilton STAR uses Hamilton CO-RE tips; Tecan Freedom EVO uses Tecan Te-PS tips; Beckman Coulter Biomek uses Beckman-specific tips. Third-party compatible robotic tips from Nest Scientific and equivalent manufacturers provide equivalent dimensional tolerances at lower cost and are certified DNase/RNase-free. Conductive robotic tips (carbon-doped polypropylene) are required on instruments using capacitive liquid-level detection (Hamilton CO-RE cLLD, Tecan cLLD) to confirm tip immersion depth. Deep-Well Plates Standard automation deep-well plates are 96-well, 2 mL per well (round- or square-bottom) in polypropylene, ANSI/SLAS footprint, with a fully skirted base for robotic gripper handling. Square-well formats maximise working volume and are preferred for DNA/RNA extraction automation. Round-bottom wells facilitate pipette tip access to the well base and pellet resuspension. Reagent Reservoir Plates Reagent reservoirs supply bulk reagent to the robotic arm in a format sized for 8-channel, 12-channel, or 96-channel head aspirations. Single-well troughs (290 mL) supply volumes for large-scale reagent additions. 12-channel troughs (22 mL per channel) and 8-channel troughs (32 mL) allow different reagents in adjacent channels for parallel dispensing. Confirm reservoir dead volume against your platform's minimum aspiration height specification. Sealing Mats Pierceable aluminium foil seals protect samples during processing and allow robotic needle or tip-based piercing for closed-tube aspiration. Silicone sealing mats provide resealable access to individual wells for sequential robotic access without contamination of adjacent wells. 
<h2 dir="ltr"> Specifications Context</h2>
 Automation consumables from Nest Scientific conform to ANSI/SLAS 1-4:2004 footprint and well-position standards. Conductive robotic tips use carbon-doped polypropylene with surface resistivity in the 10&sup2;&ndash;10⁶ &Omega; range for reliable capacitive liquid-level detection. All Nest Scientific automation consumables are certified DNase-free, RNase-free, non-pyrogenic, and endotoxin-free under ISO-certified cleanroom production. Hamilton STAR, Tecan Freedom EVO, Beckman Coulter Biomek i-Series, and PerkinElmer JANUS remain the dominant liquid handling automation platforms in North American research labs.&nbsp;

Pipette Tips for Agilent Robotic System

AF250A-9-NS Pipette Tips by MBP are 250 µL filtered, E-beam sterilized automation tips for Agilent Bravo and VPrep liquid handling systems, supplied in SBS-format 96-tip racks and certified DNase-free, RNase-free, and pyrogen-free.

Filtered Pipette Tips

<h2 dir="ltr"> What Are Filtered Pipette Tips?</h2>
 Filtered pipette tips contain a hydrophobic aerosol-barrier plug &mdash; polyethylene (PE) frit or cellulose &mdash; embedded inside the tip body, positioned to intercept aerosol and liquid that would otherwise travel up through the tip collar into the pipette barrel during dispensing or when handling volatile or splashing samples. The filter protects the pipette barrel from internal contamination (which requires costly professional decontamination) and protects samples from cross-contamination by previously deposited nucleic acids, proteins, or biohazardous material in the barrel. Filtered tips are the standard consumables for PCR and qPCR setup, RNA extraction, cDNA synthesis, working with radioactive or biohazardous agents, and any workflow where a single contaminated barrel could compromise a run or an experiment. Non-filtered tips remain appropriate for routine buffer, media, and reagent dispensing where cross-contamination through the barrel is not a concern. Use filtered tips for all nucleic acid work, PCR, and biohazardous samples; use standard tips for routine buffer and reagent dispensing.

<h2 dir="ltr"> How to Choose Filtered Pipette Tips</h2>
 Filter Material: Polyethylene Frit vs Cellulose Hydrophobic PE frits are the most common and most studied aerosol-barrier material; they block liquid ingress reliably without absorbing sample material or releasing fibres. Cellulose filters are used in some barrier tips (including the original Thermo Barrier tips); they are effective aerosol barriers but can absorb a small volume of aqueous sample, relevant at &le;10 &micro;L, where the absorbed volume is proportionally significant.
Universal Fit vs LTS-Compatible Filtered Tips Universal filtered tips use standard collar geometry (3.8 mm for &le;10 &micro;L, 6.1 mm for &le;200 &micro;L) and fit Eppendorf, Rainin Classic (non-LTS), and Thermo pipettes. LTS-compatible filtered tips use Rainin's cylindrical LTS mounting geometry and are required for Rainin LTS pipettes.&nbsp;
Low-Retention Filtered Tips Low-retention filtered tips combine an aerosol barrier with a hydrophobic inner tip wall, reducing liquid adhesion during dispensing. They are recommended for small-volume (&le;10 &micro;L) nucleic acid work, RNA, protein, and enzyme dispensing, where both contamination protection and volume accuracy are critical.
Volume Range Filtered tips are available across 10 &micro;L (P2&ndash;P10), 20 &micro;L (P20), 100 &micro;L (P100), 200 &micro;L (P200), 300 &micro;L, 1,000 &micro;L (P1000), and 1,250 &micro;L extended formats. Extended-length filtered tips reach deep into 15 mL and 50 mL conical tubes for nucleic acid elution and sample transfer steps.
Packaging Filtered tips are typically sterile-racked (96/rack, 10 racks/box); reload/refill formats are available for high-volume filter tip users.

<h2 dir="ltr"> What Are LTS-Compatible Filter Tips?</h2>
 LTS-compatible filter tips combine two design features: the cylindrical collar geometry of Rainin's LiteTouch System (LTS), which mates with Rainin LTS pipette shafts for low-insertion-force ergonomic operation, and an integrated hydrophobic aerosol-barrier filter element that prevents aerosol droplets and liquid from reaching the pipette barrel. They are the required tip format for Rainin LTS labs running PCR, qPCR, RT-PCR, RNA extraction, nucleic acid dispensing, or any contamination-sensitive workflow where both LTS ergonomics and aerosol protection are needed simultaneously. LTS filter tips are the single correct format for Rainin LTS users doing PCR, RNA, or biohazardous work &mdash; no substitution with universal filtered tips is possible.

 Confirm LTS Instrument Only pipettes displaying 'LTS' in the model designation &mdash; Pipet-Lite XLS+ LTS, Pipet-Lite M LTS, L8 LTS, L12 LTS &mdash; accept LTS tips. Standard Rainin models (older PIPET-LITE without 'LTS') and all non-Rainin pipettes require universal-fit tips, not LTS-specific tips. Low-Retention Filter Tips for Small Volumes Low-retention LTS filter tips combine the LTS mount, aerosol barrier, and hydrophobic inner wall. Use them when dispensing &le;20 &micro;L of RNA, enzyme, or protein solutions where maximum volume recovery plus contamination protection are simultaneously required &mdash; the most stringent tip specification for Rainin LTS users. Volume Range Common LTS filter tip volumes: 20 &micro;L, 200 &micro;L, 300 &micro;L, 1,000 &micro;L, and 1,200 &micro;L. Confirm the exact volume range available in LTS-compatible filter format from your supplier, as not all volumes are available in every format from every manufacturer. OEM vs Third-Party Rainin OEM filter tips for LTS are specified to the tightest cylindrical geometry tolerance. LTS filter tips are available in sterile racked and refill stacked-box formats with RNase/DNase/non-pyrogenic certification. For routine research use, third-party LTS filter tips offer equivalent performance at 20&ndash;40% lower cost. Packaging LTS filter tips are available in hinged racks (10 racks &times; 96 = 960 tips/box) and refill stacked-box inserts. Sterile options are standard across the range. 
<h2 dir="ltr"> Specifications Context</h2>
 LTS-compatible filter tips are manufactured from virgin polypropylene (PP) with hydrophobic PE filter frits; low-retention variants use hydrophobic resin for reduced surface adhesion.&nbsp;LTS filter tips: certified RNase-free, DNase-free, non-pyrogenic, CE and FDA-listed, in sterile refill stacked-box format. Multiple third-party manufacturers supply LTS-compatible filter tips at 20&ndash;40% below Rainin OEM pricing, with equivalent documented performance for research workflows.&nbsp;

Serological Pipettes

<h2 dir="ltr"> What Are Serological Pipettes?</h2>
 Serological pipettes are calibrated, graduated, sterile polystyrene disposable pipettes used with a motorised pipette controller to transfer measured volumes of liquid in the 1&ndash;100 mL range. They are the primary tool for cell culture media transfer, buffer preparation, reagent dispensing in volumes above 1 mL, and serial dilutions requiring volumetric accuracy in the millilitre range. They differ from aspirating pipettes &mdash; which have no graduations and are used only for vacuum-assisted waste removal &mdash; and from microcentrifuge tubes, which are not dispensing instruments. Serological pipettes are the correct format for any measured liquid transfer &ge;1 mL in cell culture or reagent preparation; pair them with a motorised pipette controller for safe, ergonomic operation.

<h2>How to Choose Serological Pipettes</h2>
 Volume: Standard Sizes and ISO 7550 Colour Coding ISO 7550 assigns a specific colour code to each serological pipette volume: 1 mL = red; 2 mL = yellow; 5 mL = blue; 10 mL = orange; 25 mL = green; 50 mL = purple (pink/violet depending on supplier). Colour coding allows quick visual volume identification when multiple sizes are in use simultaneously in a BSC. Packaging: Individual Wrap vs Bulk Individually wrapped sterile pipettes are required for cell culture, molecular biology, and aseptic technique. Plastic/plastic peel-open packaging eliminates paper particulate from paper/plastic wrappers &mdash; important in sensitive cell culture applications and for RNA work. Bulk-packed (canister or bag) formats are cost-effective for non-sterile applications such as buffer preparation and reagent dispensing in fume hoods. Construction: 1-Piece vs 3-Piece 1 mL, 2 mL, and 5 mL serological pipettes are typically one-piece moulded polystyrene constructions. 10 mL, 25 mL, and 50 mL pipettes use 3-piece ultrasonically welded construction (Globe Scientific) for the body-to-cone and body-to-cap joints &mdash; essential for the structural integrity of larger formats under aspiration vacuum. Tip and Graduation Features Negative graduations (markings above the nominal maximum) allow volumes slightly above nominal to be read. Fine-point tips with slow drip-off improve pipetting accuracy during cell culture media transfers. Some brands offer Wobble-not-style pipettes with reduced barrel flex for easier single-hand operation. Filter Plug Material Cotton filter plugs are standard; synthetic plugs (polyethylene or polypropylene) are preferred when processing organic solvents or any media that might wick through a cotton plug.

<h2 dir="ltr"> Specifications Context</h2>
 Serological pipettes are manufactured from optically clear virgin polystyrene in Class 100,000 cleanroom conditions. Sterility: individually wrapped pipettes are EO-sterilised to SAL 10⁻⁶; non-pyrogenic, non-cytotoxic, DNase-free, and RNase-free per lot. ISO 7550 defines colour coding for serological pipettes; many US suppliers follow this standard, though it is not universally mandated. Calibrated to deliver (TD) with blow-out (marked with a double band or 'TD' marking) &mdash; all liquid must be expelled from the tip for accurate delivery. Globe Scientific, Nest Scientific, and Falcon remain the dominant serological pipette brands in North American cell culture labs.&nbsp;
