Petri Dishes

<h2 data-section-id="8oh3r3" data-start="0" data-end="36">What Are Laboratory Petri Dishes?</h2>
&nbsp;
A petri dish is a shallow, circular, flat-bottomed lidded container used for culturing microorganisms such as bacteria and fungi on solid agar-based growth media. The standard laboratory format is 90 mm diameter &times; 15 mm depth, which provides an optimal surface area for colony isolation, enumeration, and antimicrobial testing. First introduced by Julius Richard Petri in 1887, the petri dish remains one of the most essential tools in microbiology for applications such as streak-plate isolation, colony-forming unit (CFU) counting, antimicrobial susceptibility testing (Kirby-Bauer method), environmental monitoring, and general microbial identification. Disposable polystyrene petri dishes are manufactured under cleanroom conditions, gamma sterilized (SAL 10⁻⁶), and produced as DNase/RNase-free consumables for contamination-sensitive workflows. Polystyrene dishes should not be autoclaved, as high heat can deform the material; reusable glass dishes are used when heat sterilization or chemical resistance is required.

<h2 data-section-id="jngrvt" data-start="1064" data-end="1093">How to Choose Petri Dishes</h2>
&nbsp;
Size
The 90 mm petri dish is the global standard used in most clinical and research laboratories because it fits standard incubator racks and supports typical agar volumes of 15&ndash;20 mL. Smaller 60 mm dishes are used for teaching exercises, limited sample volumes, or cost-efficient plating, while larger 150 mm dishes provide increased surface area for dense cultures, slow-growing organisms, or specialized susceptibility testing applications.
Lid: Vented vs. Non-Vented
Vented lids allow controlled gas exchange, helping maintain aerobic conditions and reduce condensation buildup during incubation. Non-vented lids are used when a sealed environment is required, such as in anaerobic systems, transport conditions, or moisture-sensitive applications where evaporation must be minimized.
Material
Polystyrene (PS) is the most commonly used material for disposable microbiology petri dishes due to its clarity, low cost, and consistent manufacturing quality. Polypropylene (PP) dishes offer higher heat resistance and can withstand autoclave conditions, but they are less optically clear. Borosilicate glass petri dishes are reusable, chemically resistant, and suitable for workflows requiring repeated sterilization or harsh chemical exposure.
Surface Treatment
Non-treated polystyrene dishes are used for standard bacterial and fungal culture. Tissue culture (TC)-treated dishes have a surface modification that promotes cell attachment and are intended for mammalian cell culture applications, not routine microbiology work. Selecting the correct surface treatment ensures accurate microbial growth and prevents unnecessary cost.
&nbsp;
<h2 data-section-id="1jl751w" data-start="3400" data-end="3425">Specifications Context</h2>
&nbsp;
Modern laboratory petri dishes are manufactured from high-grade virgin polystyrene under controlled cleanroom conditions to ensure consistency in agar surface quality and colony morphology. Stacking rings on the dish base allow airflow and thermal equilibration during incubation. In standardized microbiology methods such as CLSI, EUCAST, and AOAC protocols, 90 mm petri dishes are the preferred format for CFU counting and antimicrobial susceptibility testing. A typical agar volume of 15&ndash;20 mL per 90 mm plate ensures consistent depth and reliable diffusion characteristics for microbiological assays. Together, petri dishes, inoculating loops, and culture media form the foundation of routine bacterial culture workflows in clinical and research laboratories.

<h2>What are Blood Collection Tubes for Nucleic Acid Research?</h2>
&nbsp;
Blood collection tubes for nucleic acid research are evacuated tubes pre-filled with a lysis reagent or anticoagulant that preserve DNA and/or RNA from whole blood specimens collected by standard venipuncture. On blood draw, the lysis reagent immediately inactivates nucleases and preserves both genomic DNA and RNA&mdash;including transcriptomic expression profiles&mdash;from 3&ndash;6 mL of mammalian whole blood. They are used in gene expression analysis, next-generation sequencing, PCR-based molecular diagnostics, cell-free DNA (cfDNA) studies, and biobank archiving. Choose blood collection tubes specifically formulated for nucleic acid preservation when the sample cannot be processed within 2&ndash;4 hours of draw.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>Vacuum blood collection tubes for standardized sample volumes</li>
<li>Capillary blood collection tubes for small-volume sampling</li>
<li>Pediatric and micro-collection tubes for difficult draws</li>
<li>Sterile single-use blood collection tubes for diagnostic safety</li>
<li>General-purpose clinical and laboratory blood sampling tubes</li>
</ul>
&nbsp;
<h2>How to Choose Blood Collection Tubes</h2>
&nbsp;
DNA vs RNA vs Dual Preservation
K2 EDTA tubes (lavender cap) prevent clotting and preserve cellular morphology for CBC and flow cytometry, but RNA degrades rapidly without additional stabilization. Blood RNA stabilization tubes preserve intracellular RNA expression profiles, while dual-preservation blood collection tubes stabilize both DNA and RNA simultaneously, enabling downstream molecular analysis from a single specimen.
Blood Volume Per Tube
Standard blood collection tubes typically hold 3 mL or 6 mL. Confirm the draw volume against your extraction kit's minimum input requirement. Many NGS and RT-PCR extraction kits require 1&ndash;3 mL of whole blood per reaction, making 3 mL tubes sufficient for many single downstream applications.
Processing Window
For immediate processing (within 2 hours), standard K2 EDTA tubes are generally suitable. For delayed processing or sample shipment, choose blood collection tubes specifically formulated to stabilize nucleic acids according to the manufacturer's validated storage conditions.
Anticoagulant Type
K2 EDTA is the preferred anticoagulant for most molecular biology applications, including PCR and NGS. K3 EDTA may be used in some automated laboratory systems. Heparin is a known PCR inhibitor and should generally be avoided for nucleic acid workflows. Citrate tubes are not typically used for nucleic acid preservation.
Regulatory Compliance
For clinical or regulatory-submission workflows, confirm whether the blood collection tube has the appropriate regulatory approval or clearance for your intended application. Research-use-only (RUO) products are not intended for diagnostic use unless specifically authorized.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Standard evacuated blood collection tubes are commonly manufactured from medical-grade PET or glass. K2 EDTA tubes should be gently inverted 8&ndash;10 times immediately after collection to ensure complete anticoagulant mixing. Nucleic acid preservation tubes are available for both immediate processing and stabilized transport, depending on the manufacturer. DNA and RNA yield varies with donor characteristics, collection volume, storage conditions, and the extraction method used.

Mag Beads

<h2>What Are Magnetic Bead HMW DNA Extraction Kits?</h2>
&nbsp;
A magnetic bead HMW DNA extraction kit uses Solid Phase Reversible Immobilization (SPRI)-type magnetic beads to bind genomic DNA released by gentle lysis, with a magnetic separator handling wash and elution steps in place of centrifugation, columns, or vacuum manifolds, producing fragment sizes in the 50-150 kb range depending on how beads are resuspended during elution. Related entities include PacBio Nanobind-type bead chemistry, KingFisher-compatible automated magnetic particle processors, A260/280 and A260/230 purity thresholds above 1.8, and downstream long-read sequencing library preparation for PacBio and Oxford Nanopore platforms. Choose magnetic bead HMW kits when fragment sizes in the 50-150 kb range meet your long-read sequencing needs, and you want to avoid centrifugation-based shearing.

</ul>
&nbsp;
<h2>How to Choose a Magnetic Bead HMW DNA Kit</h2>
&nbsp;
Bead Resuspension Method and Fragment Size Tradeoff
Fragment size from magnetic bead HMW kits depends on how beads are resuspended after washing: gentle tube tapping typically yields fragments in the 50-150 kb range, while vortexing produces somewhat smaller fragments (around 40-100 kb) but may improve recovery consistency. If your sequencing application benefits from the largest possible fragments (e.g., resolving large structural variants), prioritize tapping-based resuspension protocols even if yield is marginally lower.
Sample Input and Expected Yield
Magnetic bead HMW kits for blood, cells, and tissue typically specify inputs such as 200 ul of fresh/frozen whole blood, 1 million cells, or up to 8 mg of tissue, with a minimum yield around 3 ug of HMW gDNA&mdash;matching the input requirements of PacBio library preparation (around 1 ug above 30 kb) and Oxford Nanopore ligation kits (100 ng to 1.5 ug). Confirm your sample type matches a documented protocol within the kit family rather than assuming a single universal protocol.
No Centrifuge, Column, or Vacuum Required
Unlike silica spin-column or 96-well plate HMW approaches, magnetic bead HMW kits eliminate centrifugation, columns, and vacuum manifolds entirely, relying only on a magnetic separator for all wash and elution steps. This simplifies equipment requirements for labs without access to specialized centrifuge rotors, though a magnetic stand or automated magnetic particle processor is still required.
Purity Ratios and RNA Removal
A260/280 and A260/230 ratios greater than 1.8 are generally preferred for HMW DNA from magnetic bead kits, with near-complete RNA removal reported as a feature of bead-based HMW chemistry. Ratios below this threshold can indicate protein or salt contamination requiring troubleshooting before proceeding to expensive long-read library preparation.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
The defining specifications for magnetic bead HMW DNA extraction are the fragment size achievable via the bead resuspension method chosen, sample-specific input requirements relative to the kit's documented minimum yield, and purity ratios above 1.8 for both A260/280 and A260/230. A kit yielding around 3 ug of DNA in the 50-150 kb range from 200 ul whole blood, 1 million cells, or up to 8 mg tissue meets standard PacBio and Nanopore library preparation inputs without centrifugation.&nbsp;

<h2>What Are Magnetic Bead Plasmid DNA Extraction Kits?</h2>
&nbsp;
Magnetic bead plasmid DNA kits use superparamagnetic nanoparticles, typically silica-coated or anion-exchange-functionalized, suspended in optimized binding buffers to capture plasmid DNA from bacterial lysate. After alkaline lysis of E. coli culture (0.5-5 mL per reaction), the beads bind DNA; an external magnetic field then immobilizes the beads so supernatant, RNA, and proteins are washed away without centrifugation. The purified DNA is eluted in water or low-salt buffer and is ready for downstream use. Throughput scales from single-tube manual processing to 96-well plate automation on KingFisher Duo, MagnetaPure 32, or ASSIST PLUS liquid handlers. Choose magnetic bead kits when your lab runs plasmid minipreps at scale (24+ samples/run) or when centrifuge-free automation is required.

&nbsp;
<h2>How to Choose Magnetic Bead Plasmid Kits</h2>
&nbsp;
Automation Platform Compatibility
Bead-based kits are designed for specific magnetic rod or liquid-handler platforms. Confirm compatibility before ordering: NucleoMag Plasmid kits are validated for MagnetaPure and IsoPure Mini; MagJET kits are optimized for the KingFisher series; MagMAX Pro HT kits are designed for high-throughput centrifuge-free workflows. Using a kit outside its validated platform may require buffer volume adjustments and is not supported by the manufacturer.
Bead Type and DNA Binding Capacity
Silica-coated magnetic beads use chaotropic binding chemistry similar to spin columns; anion-exchange-functionalized beads offer higher selectivity for covalently closed circular (CCC/supercoiled) plasmid. Standard miniprep bead kits bind 5-20 ug from 1.5 mL culture; scaled protocols for 5 mL can yield up to 50 ug. Check binding capacity against your expected yield to avoid saturation.
High-Copy vs Low-Copy Plasmid
Most bead-based kits are validated for standard high-copy plasmids (pUC, pBR322 derivatives). Low-copy constructs such as fosmids or BACs require longer lysis times and may need protocol modifications; check the kit's validated plasmid types before purchasing for non-standard vectors.
Elution Volume and Concentration
Bead protocols typically elute in 50-100 uL. If downstream transfection requires high DNA concentration, choose kits that support low-volume elution (50 uL) or perform a secondary concentration step. Check that the eluate is compatible with your downstream assay buffer conditions.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Plasmid DNA purity from bead-based kits is evaluated by the A260/A280 ratio (target 1.8-2.0) and the A260/A230 ratio (&gt;1.8). Supercoiling percentage (measured by agarose gel densitometry) should exceed 80% for standard transfection applications. Automated 96-well bead workflows complete plasmid isolation in 30-60 minutes for a full plate, compared to 1-2 hours for centrifuge-based spin-column processing of the same number of samples. All kits are Research Use Only (RUO).

Pipette Tips

<h2 dir="ltr">What Are LTS-Compatible Pipette Tips?</h2>
 LTS (LiteTouch System) pipette tips use a cylindrical collar that mates with the cylindrical shaft of Rainin LTS pipettes, as opposed to the conical taper used on standard universal-fit tips. The cylindrical-to-cylindrical interface reduces the insertion force needed to seat the tip, lowering the repetitive-strain load on the hand and wrist during high-throughput pipetting &mdash; the primary ergonomic benefit Rainin's LiteTouch design addresses.&nbsp; LTS tips are required for Rainin LTS pipettes &mdash; no other tip format seats correctly. Third-party LTS-compatible tips offer equivalent performance at a lower cost than OEM.

<h2 dir="ltr"> How to Choose LTS-Compatible Tips</h2>
 Confirm Your Pipette Has LTS Not all Rainin pipettes use LTS. Rainin Classic (original PIPET-LITE) and older Rainin models use standard conical shafts and require universal-fit tips. LTS is found on Rainin Pipet-Lite XLS+, Pipet-Lite M, and multichannel L8 and L12 LTS models. Look for 'LTS' in the model name on the pipette barrel before ordering LTS-specific tips. Filtered vs Non-Filtered Non-filtered LTS tips are appropriate for buffer, media, and reagent dispensing. Filtered LTS tips &mdash; with an aerosol-barrier element &mdash; are required for PCR, RNA, and contamination-sensitive work. See the dedicated [LTS Compatible Filter Tips](mbpinc.net/consumables/liquid-handling-products/filtered-pipette-tips/lts-compatible-filter-tips [confirmed]) page for filtered LTS options. Volume Range LTS tips span approximately 20 &micro;L through 5,000 &micro;L across single-channel and multichannel pipette ranges. Common volumes: 20 &micro;L (LTS SL L10/L20), 200 &micro;L (LTS SL L200, L300), 1,000 &micro;L (LTS SL L1000), and 5,000 &micro;L macro tips for large-volume LTS pipettors. OEM Rainin vs Third-Party Compatible Rainin OEM LTS tips are manufactured to the tightest dimensional specification for LTS instruments. Third-party LTS-compatible tips are precision-moulded to LTS cylindrical geometry and certified DNase/RNase-free; they provide equivalent performance in routine applications and are typically 20&ndash;40% lower in cost than Rainin OEM tips. For critical applications (clinical diagnostics, cGMP workflows), confirm compatibility with your quality system before switching from OEM. Packaging LTS tips are available in hinged racks (10 racks &times; 96 tips = 960 tips/box) and refill wafer inserts for compatible rack bases. Sterile and non-sterile options are available across the range. 
<h2 dir="ltr"> Specifications Context</h2>
 LTS-compatible tips are manufactured from virgin polypropylene; some formats use hydrophobic low-retention PP for reduced liquid adhesion.

3D Rockers

<h2>What are 3D rockers?</h2>
&nbsp;
3D rockers are laboratory rocking platforms that produce motion in multiple planes simultaneously &mdash; combining the basic back-and-forth tilt of a 2D rocker with a simultaneous lateral tilt, wave motion, or orbital component &mdash; creating a complex, three-dimensional liquid flow across the platform surface. This multi-axis motion ensures that liquid reaches every part of a flat container or membrane, including corners and edges that single-axis rocking can leave as dead zones with reduced agitation. Some 3D rockers (sometimes called nutators or wave mixers) produce a gyrating or teeter-totter-plus-wave motion rather than a strict two-axis tilt.

</ul>
&nbsp;
<h2>How to choose a 3D rocker</h2>
&nbsp;
Understand the specific motion type of each 3D rocker model
The term "3D rocker" covers different motion patterns: true dual-axis tilt (simultaneous tilt on both X and Y axes), wave-motion platforms that combine tilt with a propagating wave, and nutator-style platforms that produce a gyrating circular-tilt motion. Each produces a different liquid flow pattern, and checking the manufacturer's description of the platform motion helps in predicting how liquid will move in your specific container type.
Choose a 3D rocker when corner coverage in flat containers is important
In flat containers like square or rectangular blot boxes with right-angle corners, single-axis 2D rocking may leave residual unmixed volumes in corners on each sweep. A 3D motion that alternates between both tilt axes or produces a wave ensures liquid reaches all corners on each mixing cycle, producing more uniform washing and incubation.
Use a 3D rocker with tube holders for gentle multi-directional tube incubation
Many 3D rocking platforms accept tube holder accessories that fix microcentrifuge, 15 mL, or 50 mL tubes on the platform, providing a multi-directional mixing motion for tube contents without requiring a separate dedicated tube rotator. For gentle incubations where end-over-end rotation is not required, this is a convenient multi-use configuration.
Verify speed range and tilt angle against your application requirements
3D rockers operate at lower speeds and tilt angles than orbital shakers, typically 5&ndash;25 rpm with tilt angles of 10&ndash;30&deg;. Confirm that the rocker's speed range and tilt angle are appropriate for your specific incubation &mdash; gentle cell culture rocking requires lower speed and shallower tilt than more vigorous blot washing.
Consider platform size relative to your largest container
As with 2D rockers, the platform must accommodate the largest container you intend to use, with the additional consideration that in a 3D motion platform, a container positioned asymmetrically relative to the motion center may experience less uniform agitation at its extremes.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
The nutator-style 3D rocker uses a tilting platform driven in a slow circular path rather than a strict two-axis tilt, producing a smooth gyrating motion that keeps liquids in continuous gentle motion without the periodic deceleration of back-and-forth rocking, and is a common format used for gentle hybridization and tube mixing applications in molecular biology. As of 2026, compact 3D rocking platforms with programmable speed and timer are standard in molecular biology labs handling multiple blot and hybridization incubations simultaneously.

<h2>What are ChIP buffers?</h2>
&nbsp;
ChIP buffers are the aqueous formulations used at each stage of a chromatin immunoprecipitation protocol: cell lysis buffer disrupts the plasma membrane and releases nuclear content, nuclear lysis buffer solubilizes chromatin under conditions compatible with subsequent immunoprecipitation, sonication buffer maintains chromatin stability during shearing, ChIP dilution buffer reduces SDS concentration from the lysis buffer to allow antibody-antigen binding, sequential wash buffers with increasing ionic strength and detergent remove non-specifically bound chromatin while preserving the specific antibody-antigen-DNA complex, and elution buffer releases the captured complex from the antibody-bead resin before de-crosslinking.

Protease inhibitors must be added fresh to cell lysis and nuclear lysis buffers immediately before use, since most inhibitors are unstable in aqueous solution and lose activity quickly, and without them, nuclear proteases released during lysis will degrade histone tails and reduce ChIP enrichment of histone modifications.
Confirm SDS concentration is diluted before immunoprecipitation
High SDS in the nuclear lysis buffer is necessary for chromatin solubilization and sonication, but must be diluted approximately 10-fold using ChIP dilution buffer before antibody addition, since high SDS disrupts antibody-antigen binding and reduces immunoprecipitation efficiency.
Keep all buffers and chromatin on ice throughout the workflow after lysis
Chromatin prepared for ChIP is sensitive to non-specific interactions and protease activity after cell lysis, and maintaining samples at 4&deg;C throughout all lysis, sonication, immunoprecipitation, and wash steps minimizes these effects and preserves specificity of the enrichment.
Optimize wash buffer stringency to balance specificity against yield
ChIP wash buffers are applied sequentially at increasing ionic strength and detergent concentration to remove non-specifically bound chromatin; conditions too stringent can also strip the specific antibody-antigen-DNA complex from the beads, reducing yield, so optimization of wash conditions for each antibody-target combination improves performance.
Confirm elution buffer composition fits your downstream application
Standard ChIP elution buffers containing SDS and sodium bicarbonate release the protein-DNA complex and reverse crosslinks, but high SDS in the eluate can inhibit some NGS library preparation enzymes, making a DNA cleanup step after elution important before proceeding to library prep.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Protease inhibitor cocktails, added fresh to lysis buffers immediately before ChIP, are a standard component across kit formats and in-house protocols, since even brief protease activity can compromise histone modification detection by degrading the histone tails that ChIP antibodies recognize. As of 2026, ChIP buffer formulations compatible with low-input chromatin and NGS library preparation continue to be optimized for primary cell and tissue ChIP workflows.

BioFactory Accessories

<h2 dir="ltr"> What are Accessories for NEST BioFactory&trade; Systems?</h2>
 NEST BioFactory&trade; accessories are the replacement caps, silicone tubing, vent filters, overcaps, and pre-assembled closed-system cap assemblies used to configure BioFactory units for closed aseptic liquid transfer, gas exchange management, and multi-unit serial connections in cGMP and research-scale bioprocess workflows. The accessory set enables the BioFactory narrow-mouth cap to function as a closed-system liquid transfer port &mdash; media, wash buffer, trypsin, and cell harvest supernatant are transferred in and out through the silicone tubing connection without opening the vessel. Accessories for the BioFactory are required when operating the BioFactory as a closed system; for simple open-pour workflows using wide-mouth caps, standard vent and plug seal caps are the only accessories needed.

<h2 dir="ltr"> Key BioFactory Accessory Categories</h2>
 BioFactory Cap with Silicone Tube (CPC or Luer Connector) The BioFactory cap with silicone tube is the primary closed-transfer accessory: an adaptor cap that fits the narrow-mouth port of the BioFactory unit, pre-assembled with 80 cm of silicone tubing and a terminal connector &mdash; either a male CPC (clamped pressure connector / quick-connect) or a standard Luer lock &mdash; for coupling to peristaltic pumps, other BioFactory units, centrifuge tubes, or PETG media bottle assemblies. Two tubing I.D. &times; O.D. configurations are available: 1/4" I.D. &times; 3/8" O.D. and 3/8" I.D. &times; 5/8" O.D., covering standard peristaltic pump head bore sizes. The female sealing cap included with each assembly caps the connector between uses, maintaining sterility. Overcaps: Vented and Solid Overcaps are secondary dust and contamination barriers placed directly on top of the BioFactory adaptor caps during culture incubation. The vented overcap contains a 0.22 &micro;m hydrophobic breathable membrane, allowing gas exchange through the cap stack while blocking particles and microbial contamination &mdash; used during active shaker or orbital incubation when the unit's primary cap is an adaptor cap rather than a vented cap. The solid overcap provides an additional dust and contamination seal with no gas exchange &mdash; used for short-term storage or transport outside the incubator. SPT-50 Silicone Hose SPT-50 silicone hose (3/8" I.D. &times; 5/8" O.D., 50 inches / 15 meters) is the bulk tubing used to connect multiple BioFactory units in series, connect BioFactory ports to peristaltic pump heads, or extend the reach of the transfer cap assembly. SPT-50 tubing is manufactured from silicone, is individually wrapped and sterile, and passes dissolution testing per BPOG (BioPhorum Operations Group) criteria per NEST product documentation, supporting its use in biopharmaceutical production environments. Premium Accessory Package NEST offers a BioFactory Accessory Premium Package that includes 2 different adaptor caps, 1 hose clamp, 1 adaptor connector, 1 vent filter (50 mm), 1 additional hose clamp, and 15 m of SPT-50 silicone hose &mdash; all individually wrapped and sterile in a single kit. This package provides all components needed to set up a closed-system BioFactory media management workflow from a single kit, reducing the number of individual part orders required. Vent Filters for Gas Exchange Management For BioFactory units using adaptor caps rather than standard vented caps, 50 mm inline vent filters (0.22 &micro;m hydrophobic PTFE membrane) are installed on the air inlet/outlet tubing line to maintain sterile gas exchange during media addition, harvest, and incubation. The vent filter is rated for high flow rates without creating excessive back-pressure that would resist liquid movement through the system. Compatibility: Narrow-Mouth BioFactory Units Only All BioFactory accessory caps and tubing assemblies are designed exclusively for the narrow-mouth BioFactory configuration. Wide-mouth BioFactory units use standard wide-mouth vent and plug seal caps only; they are not compatible with accessory cap assemblies. Confirm that your BioFactory units have narrow-mouth ports before ordering the accessory cap set. 
<h2 dir="ltr"> Specifications Context</h2>
 NEST BioFactory&trade; accessory silicone tubing and cap assemblies are manufactured from USP Class VI silicone (TPE/silicone) and polycarbonate or PP cap bodies, individually wrapped and sterile.
