Liquid Handling

Pipette Tips

<h2 dir="ltr">What Are Pipette Tips?</h2>
 Pipette tips are disposable polypropylene cones that attach to the shaft of an air-displacement pipette, forming the liquid-contact surface for aspiration and dispensing. The seal between the tip collar and the pipette shaft is the single most important factor in volumetric accuracy; a poorly fitting tip introduces systematic volume error that causes the instrument to deviate from its calibrated specification. Tips span micro volumes (0.1&ndash;10 &micro;L) through standard (20&ndash;200 &micro;L and 100&ndash;1,000 &micro;L) to high-volume (up to 1,250 &micro;L), with variants for filtered aerosol protection, low-retention liquid release, extended reach into deep vessels, and wide-bore dispensing of viscous samples.&nbsp;

<h2 dir="ltr">How to Choose Pipette Tips</h2>
 Collar Size and Pipette Compatibility Tip collar diameter determines fit: 3.8 mm collar for &le;10 &micro;L pipettes; 6.1 mm collar for &le;200 &micro;L; approximately 7.5&ndash;8.0 mm collar for P1000 pipettes. Universal fit tips use these standard collar sizes and are compatible with Eppendorf Research, Rainin Classic (non-LTS), Thermo Finnpipette, and Sartorius/BioHit. Rainin LTS and Eppendorf epT.I.P.S. use proprietary collar geometry and require instrument-specific tips. Filtered vs Non-Filtered Aerosol-barrier filter tips contain a hydrophobic PE or cellulose plug that blocks aerosol and liquid from reaching the pipette barrel; required for PCR, qPCR, and RT-PCR setup, RNA extraction, and work with biohazardous samples. Non-filter standard tips are appropriate for buffer, media, and reagent dispensing where cross-contamination through the barrel is not a concern. Low-Retention vs Standard Polypropylene Low-retention tips are injection-moulded from hydrophobic polypropylene with reduced surface energy or coated to minimise liquid adhesion on the inner wall. They improve accuracy at &le;10 &micro;L and for dispensing viscous, protein-containing, or organic solvent samples. Standard PP tips leave small residual volumes in the tip after dispensing; this residue is negligible at 200 &micro;L but significant at 2&ndash;5 &micro;L. Extended-Length and Wide-Bore Extended-length tips (also called long tips or gel-loading tips) reach into deep 15 mL and 50 mL tubes, cryovials, and electrophoresis gel wells. Wide-bore tips have an enlarged aperture for dispensing viscous samples, cell suspensions, and tissue lysates without shearing. Packaging Format Hinged 96-tip racks are standard for manual pipetting. Reload inserts fit into reusable rack bases to reduce per-tip cost and plastic waste. Bulk bags provide the lowest cost per tip for non-sterile applications.
&nbsp;
<h2 dir="ltr">Specifications Context</h2>
 Pipette tips are certified DNase-free, RNase-free, ATP-free, human DNA-free, PCR inhibitor-free, and pyrogen-free per independent lot testing. Virgin polypropylene free of additives, antistatic agents, and dyes is the standard material. ISO 8655 compliance for the pipette system depends on tip-pipette seal quality; confirm tip compatibility with your specific pipette model.&nbsp; Sorenson Bioscience universal and filtered tips, Globe Scientific, and Nest Scientific lines are stocked by MBP Inc.&nbsp;

<h2 dir="ltr"> What Are Universal Fit Pipette Tips?</h2>
 Universal fit pipette tips use collar diameters standardised across most major air-displacement pipette brands, allowing a single tip product to seat on pipettes from multiple manufacturers. The three primary collar sizes are: 3.8 mm for &le;10 &micro;L tips, 6.1 mm for &le;200 &micro;L tips, and approximately 7.5&ndash;8.0 mm for P1000 tips. These collar sizes cover Eppendorf Research Plus, Rainin Classic (non-LTS), Thermo Finnpipette, Sartorius/BioHit, and VWR pipettes. Universal fit tips cover most lab pipettes at a lower cost per tip &mdash; the exception is Rainin LTS, which needs dedicated LTS tips.

 Volume Range: Match Tip to Pipette 10 &micro;L universal tips (3.8 mm collar) cover 0.1&ndash;10 &micro;L single-channel pipettes and the P10 range. 200 &micro;L universal tips (6.1 mm collar) cover P20, P50, P100, and P200 pipettes. 1,000 &micro;L universal tips cover P1000 pipettes and are available in standard-length and extended-length formats. 1,250 &micro;L macro universal tips accommodate high-volume dispensing steps in the 1,000&ndash;1,250 &micro;L range. Standard vs Filtered Universal Tips Standard universal tips are sufficient for buffer, media, and reagent dispensing. Filtered universal tips &mdash; with hydrophobic PE or cellulose aerosol barrier &mdash; are required for PCR setup, RNA work, and any contamination-sensitive application. Using filtered tips universally reduces contamination risk in shared pipettes at the cost of approximately 1.5&ndash;2&times; the price of standard tips. Low-Retention Universal Tips Low-retention universal tips minimise residual volume on the inner tip wall. This matters at &le;10 &micro;L, where standard tips may retain 0.2&ndash;0.5 &micro;L, creating a systematic under-delivery error. Sorenson's universal low-retention tips maintain compatibility with all major standard-collar pipettes. Packaging Format Racked (hinged 96-tip rack): standard for manual pipetting. Reload inserts: drop into reusable rack bases; 20&ndash;30% lower per-tip cost and reduced plastic. Bulk (non-sterile bag): lowest cost per tip for non-sterile buffer/media work. Sterile racked tips are required for cell culture, RNA, and clean applications. OneTouch / Ergonomic Formats OneTouch reload formats allow the full tip insert to be loaded into the pipette simultaneously, reducing repetitive-strain impact from individual tip-loading in high-throughput workflows. 
<h2 dir="ltr"> Specifications Context</h2>
 Universal fit tips are manufactured from 100% virgin polypropylene, certified DNase-free, RNase-free, ATP-free, human DNA-free, pyrogen-free, and PCR inhibitor-free per lot. Sorenson Bioscience universal tips are manufactured in a Class 100,000 cleanroom, pre-sterilised, and sold through MBP Inc. in standard racks, EcoRack reloads, and bulk formats. Universal fit tips remain the highest-volume tip category in North American research labs due to multi-brand compatibility and lower cost per tip versus pipette-specific variants.&nbsp; 
If you&rsquo;re setting up a workflow or mixing pipette brands in the same lab, it&rsquo;s usually worth sorting tip compatibility early &mdash; it removes a lot of small daily friction that adds up over time. <a href="https://mbpinc.net/contact-us">Contact the MBP team</a> to get a tailored quote!

Universal Fit Pipette Tips

<h2 dir="ltr">What Are Pipette Tip Refill Stations?</h2>
 A pipette tip refill station consists of two components: a durable outer rack frame (typically polypropylene or polycarbonate) that holds tips at standard 9 mm well spacing, and disposable reload inserts &mdash; tip wafer trays pre-loaded with 96 tips &mdash; that drop into the frame to replace a depleted set. Once the insert is exhausted, the rack base is retained, and a new insert is loaded, rather than discarding the entire rack assembly. This system is designed for high-throughput labs that consume hundreds of racks per month; at that scale, the reduction in plastic waste (up to 60%) and per-tip cost (typically 15&ndash;30% lower than equivalent racked tips) is meaningful over a year. Reload inserts carry the same universal-fit collar geometry and purity certifications as standard hinged racks.&nbsp; Refill stations make economic and environmental sense when your lab replaces more than two full cases of racked tips per month.

</ul>
<h2 dir="ltr"> How to Choose a Refill Station System</h2>
 Rack Base Compatibility Reload inserts are designed to fit specific rack base models &mdash; they are not universally interchangeable. Confirm the rack base brand and model before ordering reload inserts; for example, Sorenson EcoRack reload inserts fit Sorenson EcoRack bases, USA Scientific LTS refill wafers fit USA Scientific racks, and Nest Scientific inserts fit Nest frames. MBP Inc. supplies matched rack bases and insert systems &mdash; contact the team if unsure which base fits your existing racks. Sterile vs Non-Sterile Inserts Sterile reload inserts (EO-sterilised or gamma-irradiated) are required for PCR setup, RNA work, cell culture, and any sterility-sensitive application. Non-sterile inserts are suitable for routine buffer, media, and reagent dispensing where the pipette and tip will not contact a sterile sample. Volume Range Refill inserts are available in the same volume range as racked tips: 10 &micro;L, 200 &micro;L, 300 &micro;L (select formats), and 1,000&ndash;1,250 &micro;L. Confirm that the same volume range is available for both the rack base and the reload insert from your supplier. Filter vs Non-Filter Inserts Filter reload inserts &mdash; with integrated aerosol-barrier elements &mdash; are available for labs requiring contamination protection in PCR or nucleic acid work. Non-filter reload inserts are the economical choice for routine liquid handling. OneTouch / Stacked Loading Systems Some refill formats (e.g., Rainin SpaceSaver, Sorenson EcoRack, Biotix reload) offer stacked magazine-style packaging where multiple inserts are stacked in a column; a fresh insert auto-advances when the previous is depleted, reducing tip-station restocking frequency in high-throughput workflows. 
<h2 dir="ltr"> Specifications Context</h2>
 Reload insert tips are manufactured from the same virgin polypropylene as standard racked tips, certified DNase-free, RNase-free, human DNA-free, ATP-free, and PCR inhibitor-free per lot. Rainin SpaceSaver inserts reduce plastic waste by up to 80% versus hinged racks using recyclable PETE packaging. Biotix uTIP reload inserts reduce plastic waste by 30%; Sorenson EcoRack inserts reduce waste by up to 60%.

Pipette Controller

<h2 dir="ltr"> What Are Pipette Controllers?</h2>
 A pipette controller (also called a pipetting aid, motorised pipette filler, or pipette boy) is a battery-operated instrument that accepts and drives 1&ndash;100 mL glass or plastic serological pipettes, replacing the rubber bulb, Pi-pump, and manual mouth-pipetting techniques. A motorised rotating wheel or roller generates controlled airflow to aspirate and dispense liquid at variable speeds; a hydrophobic 0.2 &micro;m inline filter prevents liquid and aerosol from reaching the motor. Controllers accept all standard serological pipette diameters (1 mL to 100 mL) through a silicone or rubber cone adapter. They are the standard dispensing tool for media preparation, cell culture reagent transfer, serial dilutions in large volumes, and reagent bottle-to-flask transfers. The disposable consumables used in the instrument. A pipette controller is required for safe, ergonomic use of serological pipettes in any volume from 1 mL to 100 mL &mdash; the rubber bulb is not a recommended alternative.

<h2 dir="ltr"> How to Choose a Pipette Controller</h2>
 Power Source: Battery vs Rechargeable vs Mains Battery-powered controllers (AA or rechargeable internal battery) provide cordless flexibility across the bench and BSC. Rechargeable lithium-ion controllers offer 8&ndash;10 hours of continuous use per charge and charge from a base stand. Mains-powered controllers provide continuous operation without charge interruption &mdash; preferred in high-throughput cell culture facilities. Speed Control Two-speed controllers offer slow (for precise fill) and fast (for rapid dispense) modes. Variable-speed controllers with a continuous-pressure or stepless trigger allow fine-tuned flow rate adjustment for viscous media, delicate cell suspensions, or filling against gravity into narrow-neck vessels. Filter: Inline 0.2 &micro;m Hydrophobic Filter A 0.2 &micro;m hydrophobic inline filter is the critical protection component &mdash; it prevents liquid from entering the motor during accidental over-aspiration. Filters should be replaced when liquid reaches the filter or when flow resistance increases noticeably; replacement filters are sold separately for most models. Universal Cone Compatibility Confirm the controller's cone adapter accepts your pipette brand's tip diameter. Most controllers use a silicone or rubber cone that accommodates 1&ndash;100 mL serological pipettes from Falcon, Globe Scientific, and Nest Scientific without adapters. Autoclavability Controllers intended for BSC and sterile cell culture use should have an autoclavable cone, nose piece, and filter assembly. They have autoclavable lower sections; the battery/electronic module is not autoclavable. 
<h2 dir="ltr"> Specifications Context</h2>
 Standard pipette controllers accept serological pipette diameters from 1 mL (narrow shaft) through 50 mL and 100 mL (wide-body). Replacement 0.2 &micro;m hydrophobic filters are sold in packs; filter replacement interval is typically every 6&ndash;12 months or immediately after liquid ingress. It has a runtime of approximately 8 hours per charge on a single lithium-ion battery.&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.

Transfer Pipettes

<h2>What are disposable transfer pipettes?</h2>
&nbsp;
Disposable transfer pipettes are single-use plastic liquid-handling tools made from low-density polyethylene (LDPE). They are designed as a one-piece bulb-and-stem system used for transferring, dispensing, and handling small volumes of liquids in laboratory workflows.
They are commonly used as a safer and more convenient alternative to glass Pasteur pipettes. Being plastic and disposable, they eliminate the risk of breakage, reduce cross-contamination, and remove the need for separate rubber bulbs. The flexible bulb allows controlled aspiration and dispensing of reagents, samples, and solutions.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>Graduated transfer pipettes &ndash; for approximate volume measurement and controlled dispensing</li>
<li>Non-graduated transfer pipettes &ndash; for simple liquid transfer without measurement markings</li>
<li>Fine-tip transfer pipettes &ndash; for small droplets and precise spot dispensing</li>
<li>Sterile transfer pipettes &ndash; for microbiology and contamination-sensitive workflows</li>
<li>Non-sterile transfer pipettes &ndash; for routine laboratory use</li>
<li>Disposable Pasteur pipettes &ndash; for general single-use liquid handling</li>
</ul>
&nbsp;
<h2>How to choose transfer pipettes</h2>
&nbsp;
Tip style Fine-tip pipettes are used for precise work such as microplate spotting and small-volume handling. Standard tips are suitable for general transfers, while wide-bore designs are better for viscous liquids or blood samples. Longer stems help access deep containers.
Capacity and volume handling Select pipettes based on typical working volumes. Smaller pipettes are suitable for low-volume transfers, while larger ones are used for routine sample handling. The effective draw volume depends on bulb capacity and usage technique.
Graduated vs non-graduated Graduated pipettes allow approximate volume estimation and are useful in clinical and diagnostic workflows. Non-graduated pipettes are intended for general dispensing where precise measurement is not required.
Sterility requirements Sterile pipettes are used in microbiology, cell culture, and clinical applications where contamination control is essential. Non-sterile versions are suitable for general laboratory and teaching use.
Length and accessibility Long pipettes are preferred for deep vessels such as flasks and bottles, while shorter designs are used for compact tubes and small workspaces.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Disposable LDPE transfer pipettes are widely used laboratory consumables for general-purpose liquid handling in research, clinical, and educational environments. They are available in sterile and non-sterile formats with multiple tip designs and capacities to support different workflows.
These pipettes remain a standard alternative to glass Pasteur pipettes due to their safety, low cost, and reduced contamination risk in routine laboratory applications.

Pipettors Accessories

<h2 dir="ltr"> What Are Pipettor Accessories?</h2>
 Pipettor accessories are complementary tools and parts that support correct storage, calibration, maintenance, and identification of laboratory pipettors. Pipettors stored lying flat on a benchtop risk contaminating the nose cone and suffer tip ejector wear; vertical stand storage is the manufacturer-recommended practice for all brands. At a minimum, every lab needs a pipette stand to prevent bench contamination and a calibration tool to verify ISO 8655 accuracy without sending instruments out.

<h2 dir="ltr"> Key Pipettor Accessory Categories</h2>
 Pipette Stands and Carousel Racks Single-position vertical stands store one pipette upright, protecting the nose cone from surface contact. Six-position carousel stands rotate 360&deg; and hold 6 pipettors of mixed sizes &mdash; the standard for a molecular biology bench set covering P2, P10, P20, P200, P1000, and P5000. Universal-format carousels (Eppendorf, Gilson, Rainin, Biohit, Thermo) accommodate most standard pipette body diameters; manufacturer-specific stands provide a precision fit. Wall-mount holder systems save bench space in smaller workspaces. In-Lab Calibration Tools Gravimetric calibration of a pipettor requires only a calibrated analytical balance (0.0001 g resolution), distilled water, and a calibration tool specific to the pipettor model for adjusting the piston stop. Manufacturer calibration kits (e.g., Gilson Pipetman Calibration Kit, Eppendorf calibration tool) allow in-lab ISO 8655 verification without sending pipettors to an external service. ISO 17025-accredited external calibration services (Gilson, Eppendorf, Rainin) issue certified calibration reports for GLP and regulatory compliance. O-Ring and Seal Service Kits Worn O-rings and seals are the most common cause of pipettor inaccuracy and tip leakage after physical damage. Service kits specific to each pipettor model (Gilson PIPETMAN service kit, Eppendorf Research Plus service kit) include O-rings, seals, and small springs for routine preventive maintenance. Gilson recommends preventive maintenance every 1&ndash;2 years or whenever calibration verification fails. Colour-Coding Rings Colour-coded silicone rings clip onto pipette barrels for quick volume identification, user assignment, or pre/post-PCR segregation in shared labs. Eppendorf ColorTag rings are available in 12 colours and 6 sizes compatible with all Eppendorf pipette models; universal-format rings fit most major brands. Charger Stands for Electronic Pipettors Electronic pipettors (Eppendorf Research Pro, Rainin Pipet-Lite XLS+) require charger stands or base docks for overnight charging. Charger stands also serve as storage; the Eppendorf Charger Stand 2 holds and charges a single electronic model on the bench. 
<h2 dir="ltr"> Specifications Context</h2>
 Pipettor stands should be used per all major manufacturer guidelines &mdash; Eppendorf, Gilson, and Rainin all specify vertical storage as the correct position to prevent liquid ingress into the piston. ISO 8655 calibration requires distilled water at 20&deg;C, a balance with 0.0001 g resolution, and a minimum of 10 dispenses per volume setting. Eppendorf ColorTag rings are available in 6 sizes covering pipettes from 2 &micro;L to 5,000 &micro;L.&nbsp; Eppendorf, Gilson, and Rainin offer both in-lab calibration tools and ISO 17025-certified external calibration services.&nbsp;

Single Channel Pipettors

<h2 dir="ltr">What Are Single-Channel Pipettors?</h2>
 A single-channel pipettor is the single most widely used liquid handling instrument in molecular biology, cell biology, and clinical research. It transfers precise volumes between 0.1 &micro;L and 5,000 &micro;L, one well or tube at a time, using an air-displacement piston mechanism. The piston creates a partial vacuum that aspirates liquid into a disposable tip; advancing the piston fully dispenses the liquid. A spring-loaded tip ejector releases the used tip without hand contact for contamination control. Manual models depend on finger force and offer simple, battery-free operation; electronic models add programmable aspiration/dispensing speeds, multi-dispense modes, and up to 5 custom pipetting programs.&nbsp; A set of four manual single-channel pipettors (P10, P20, P200, P1000) covers 95% of molecular biology liquid handling; add electronic models for high-throughput repetitive work.

<h2 dir="ltr"> How to Choose a Single-Channel Pipettor</h2>
 Volume Range: Build a Complete Bench Set A standard four-pipettor bench set covers P10 (1&ndash;10 &micro;L), P20 (2&ndash;20 &micro;L), P200 (20&ndash;200 &micro;L), and P1000 (100&ndash;1,000 &micro;L). For sub-microliter work (sequencing, single-cell), add a P2 (0.2&ndash;2 &micro;L). For large-volume dispensing (media prep, column loading), add a P5000 (1,000&ndash;5,000 &micro;L). Avoid selecting a volume range that places your target dispense below 20% of the maximum &mdash; accuracy degrades at the low end of any range. Manual vs Electronic Manual single-channel pipettors (Eppendorf Research Plus, Gilson PIPETMAN Classic, Rainin Pipet-Lite XLS+) are the standard for routine lab work: field-calibratable, autoclavable, and requiring no power source. Electronic single-channel pipettors (Eppendorf Research Pro, Rainin Pipet-Lite XLS+ Electronic) add: programmable aspiration/dispense speed (5 speeds), multi-dispense (repeat pipetting) mode, mix mode, dilution mode, and backlight LCD volume display. Electronic models reduce hand fatigue in workflows exceeding 200&ndash;300 tip changes per day. Tip Compatibility Three tip systems cover the market: standard conical (universal fit &mdash; fits Eppendorf Research Plus, Gilson PIPETMAN, Rainin non-LTS, Thermo, Sartorius/BioHit); Rainin LTS cylindrical (requires LTS-specific tips &mdash; lower force insertion); Eppendorf epT.I.P.S. proprietary (tightest fit for Eppendorf instruments). Select the tip system that matches your pipettor purchase and existing tip inventory before committing to a brand. Autoclavability and Chemical Resistance Manual pipettors from Eppendorf, Gilson, and Rainin have fully autoclavable lower sections (121&deg;C, 15 psi, 15 min). Electronic pipettors have autoclavable nose cones only &mdash; the electronic module cannot be autoclaved. Calibration and Service All single-channel pipettors are factory-calibrated per ISO 8655. Field recalibration tools are available for Eppendorf, Gilson, and Rainin to perform in-lab gravimetric verification without external service. 
<h2 dir="ltr"> Specifications Context </h2>
 ISO 8655 Part 2 accuracy spec for a 200 &micro;L air-displacement pipettor: &plusmn;0.8 &micro;L systematic error, &le;0.3 &micro;L random error (Eppendorf Research Plus specification at 200 &micro;L). Most manual pipettors weigh 70&ndash;120 g; electronic models weigh 150&ndash;220 g. Operating temperature range: typically 15&ndash;40&deg;C. Eppendorf Research Plus, Gilson PIPETMAN Classic, and Rainin Pipet-Lite XLS+ LTS remain the three dominant single-channel pipettor platforms in North American research labs.&nbsp;
