PCR Tubes

<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 data-path-to-node="1"> Specifications Context</h2>
 Standard 96-well PCR tube racks measure approximately 130 &times; 98 &times; 33 mm (L &times; W &times; H) with 5.2 mm well diameter and 9 mm well spacing. Polypropylene construction is chemical-resistant and autoclavable at 121&deg;C. Alphanumeric embossed grid (A&ndash;H rows, 1&ndash;12 columns) matches the labelling of PCR plates and plates for straightforward sample mapping.

PCR Tube Racks

<h2 dir="ltr">What Are Individual PCR Tubes?</h2>
 Individual PCR tubes are single-reaction thin-wall polypropylene vessels supplied separately rather than in strip or plate format. The 0.2 mL format is the global standard for modern thermal cyclers with conventional 96-well block geometry, while 0.5 mL tubes are used with older or specially adapted blocks. Individual tubes offer the flexibility to set up any number of reactions without being constrained to a strip of 8 or 12, making them ideal for one-off reactions, optimisation runs, and protocols requiring varied tube counts. Choose individual tubes for variable reaction counts and when colour-coding samples matters.

 Volume: 0.2 mL vs 0.5 mL The 0.2 mL tube fits virtually all modern thermal cycler blocks, including Bio-Rad T100, Eppendorf Mastercycler NEO, and Applied Biosystems Veriti. The 0.5 mL tube is used with specific gradient blocks or older instruments; confirm block compatibility before ordering this format. Attached Cap vs No Cap Tubes with attached dome caps offer convenience and prevent cap mix-ups during high-volume workflows. Tubes with flat attached caps or sold without caps (requiring separate cap purchase) are chosen when flat optical caps or coloured caps are needed for tube tracking. Colour Options Coloured individual tubes (clear, white, yellow, red, blue, green) allow colour-based sample tracking without labelling, particularly useful in high-throughput genotyping or multiplex PCR workflows where visual differentiation reduces setup errors. Polypropylene Grade Individual tubes should be moulded from virgin polypropylene free of additives, antistatic agents, and dyes that can inhibit PCR enzyme activity. White tubes (for qPCR with fluorescence read from the bottom) must use a white polypropylene body that maximises signal reflection. 
<h2 dir="ltr"> Specifications Context</h2>
 Standard 0.2 mL individual PCR tubes have a wall thickness of approximately 0.25&ndash;0.35 mm, a conical base for complete reaction volume recovery, and are supplied in bags of 1,000 tubes for bench use.

Biofactory Systems

<h2 dir="ltr"> What are NEST BioFactory&trade; Systems?</h2>
 NEST BioFactory&trade; Systems are compact, single-use, multi-layer cell culture vessels manufactured from USP Class VI polystyrene for large-scale adherent cell culture. The BioFactory provides the growth kinetics and cell attachment characteristics of standard T-flasks, scaled up to growth areas from approximately 636 cm&sup2; (1-layer) to 25,440 cm&sup2; (40-layer) in a single vessel &mdash; making it the scale-up path from T-flask and roller bottle culture for vaccine production, monoclonal antibody manufacturing, viral vector production (lentivirus, AAV, adenovirus), and biopharmaceutical protein expression from adherent cell lines.&nbsp;
&nbsp;
<h2 dir="ltr">What you will find:</h2>

<li><a href="https://mbpinc.net/consumables/cell-culture/biofactory-systems/biofactory-system-accessories">BioFactory System Accessories:</a> Adaptor caps, overcaps, holders, vent filters, accessory packages, tubing sets, and preconfigured kits designed to support media handling and system operation.</li>
<li>Sterile fluid transfer components: CPC connectors, T- and Y-shaped connectors, sealing plugs, adaptor connectors, hose clamps, funnels, and filter/tubing assemblies for closed liquid transfer workflows.</li>
<li>Bioprocess tubing: Sterile C-Flex&reg; welding hose, SPT-50 hose, and inlet/outlet tubing compatible with BioFactory systems and media transfer applications.</li>
<li>Preassembled BioFactory configurations: Ready-to-use systems equipped with integrated vent filters, transfer tubing, or specialized cap assemblies to streamline cell culture setup.</li>
</ul>
<h2 dir="ltr"> How to Choose the Right BioFactory&trade; Layer Count</h2>
 Matching BioFactory Scale to Production Stage The 1-layer BioFactory (&asymp;636 cm&sup2;) is equivalent in surface area to approximately 8&ndash;9 standard T75 flasks &mdash; used for proof-of-concept scale-up studies transitioning from T-flask monolayer culture. The 2-layer BioFactory (&asymp;1,272 cm&sup2;) is the standard for pilot-scale viral antigen production and early-phase process development. The 5-layer (&asymp;3,180 cm&sup2;) and 10-layer (&asymp;6,360 cm&sup2;) formats suit mid-scale production runs for research-grade vaccine lots, transfection-derived protein, and pre-clinical viral vector batches. The 40-layer (&asymp;25,440 cm&sup2;) format is an industrial-scale format for commercial vaccine, mAb, and biopharmaceutical production. Closed Liquid Transfer and Contamination Reduction NEST BioFactory&trade; systems feature a narrow-mouth cap port compatible with aseptic tubing for closed liquid transfer &mdash; media, wash buffers, trypsin, and harvest supernatant can be introduced and removed through the tube port without opening the vessel. This closed-system operation eliminates the open-pour steps that create contamination risk in multi-layer roller bottle workflows and enables BSL-2 containment of pathogen-bearing cultures without biosafety cabinet&ndash;dependent open-handling. Wide-mouth caps allow direct media pouring for non-closed workflows. TC Treatment and Cell Compatibility All NEST BioFactory&trade; layers are TC-treated by vacuum plasma using the same surface treatment process as NEST cell culture T-flasks. NEST has published VERO cell culture data showing that cell morphology, adherence, and growth kinetics in the BioFactory are equivalent to those in standard T-flasks &mdash; cell attachment density, proliferation rate, and morphology are not altered by the scale-up. This linear scalability is the primary engineering advantage of multi-layer vessels over microcarrier bioreactors and packed-bed systems for adherent cell&ndash;derived products requiring 2D culture validation. Ultrasonic Welding and Particle Generation The BioFactory layers are joined by ultrasonic welding without chemical adhesives or extrinsic ingredients. NEST's welding line design minimizes particle generation at the weld joints, an important quality attribute for pharmaceutical production contexts where subvisible particle counts in harvest media must meet compendial limits. Automation and GMP Compatibility NEST BioFactory&trade; systems are compatible with automated media handling equipment. Multiple BioFactory units can be connected in series through the tubing ports for further scale-out. The double-bagged sterile packaging format supports GMP cleanroom entry requirements. NEST provides validation documentation packages (sterilization data, extractable/leachable certificates, biocompatibility reports) supporting GMP authorization for industrial cell culture production. 
<h2 dir="ltr"> Specifications Context</h2>
 NEST BioFactory&trade; Systems are manufactured from USP Class VI polystyrene in a Class 10,000 (ISO 7) dedicated cleanroom. All culture surfaces are TC-treated by vacuum plasma. Temperature range: approximately &minus;86 &deg;C to +64 &deg;C. E-beam sterilized to SAL 10⁻⁶; non-pyrogenic; double-bagged sterile packaging.

Cell Culture Inserts

<h2 dir="ltr">What are Cell Culture Inserts?</h2>
 Cell culture inserts (also called Transwell inserts or permeable supports) are sterile, single-use polystyrene well inserts with a permeable membrane floor that suspend cells above the bottom of a standard multi-well plate, creating separate apical (upper, inside insert) and basolateral (lower, outside insert in the well below) compartments. The membrane allows diffusion of media, nutrients, metabolites, and signaling molecules between the two compartments while physically separating the two cell populations.&nbsp;Choose PET membranes for imaging and clear-bottom visualization; choose PC membranes for superior cell attachment; choose pore size based on whether cells need to migrate through the membrane (&ge;3 &micro;m) or be retained on it (0.4 &micro;m and 1 &micro;m).

<h2 dir="ltr">How to Choose Cell Culture Inserts</h2>
 PET vs. PC Membrane PET (polyethylene terephthalate) membranes are optically transparent, allowing direct visualization of cells growing on the membrane by standard phase-contrast and fluorescence microscopy without removing the insert. PET is the first choice when imaging cells on the membrane is part of the experimental readout (tight-junction immunofluorescence, GFP localization, wound-healing on the membrane). PC (polycarbonate) membranes provide superior cell attachment due to their higher surface energy &mdash; often used for primary epithelial, endothelial, and intestinal cells that are difficult to culture on PET. PC membranes are opaque, blocking transmitted light microscopy through the membrane. Pore Size by Application 0.4 &micro;m pore inserts prevent cell migration and cell-cell contact between apical and basolateral compartments while allowing free diffusion of molecules &lt;0.4 &micro;m (nutrients, cytokines, small molecules, metabolites). Standard for epithelial barrier function assays (TEER measurement, permeability assays), secretion studies (measuring cytokine secretion from the basolateral side), and any co-culture where cell-cell contact must be prevented. 1 &micro;m pore inserts similarly prevent cell migration but allow slightly larger molecule diffusion &mdash; used for exosome transport studies. 3 &micro;m pore inserts allow poorly migratory cells (some endothelial, fibroblast lines) to migrate through. 8 &micro;m pore inserts support tumor cell migration, invasion, chemotaxis, and hematotaxis assays &mdash; the standard pore size for Boyden chamber&ndash;style migration and invasion assays. Plate Format and Insert Configuration NEST Scientific inserts are pre-packed in multi-well plates: 6-well plate format (6 inserts per plate), 12-well plate format (12 inserts per plate), 24-well plate format (12 inserts per plate). Inserts are centered in wells by their flange geometry, preventing the membrane from touching the well sides and creating a wicking path. The apical-basolateral gap (distance from membrane floor to well bottom) is designed to allow media access to the basolateral face and pipette access to the lower chamber for sampling. TC-Treated vs. Non-Treated Membrane TC-treated membrane inserts promote adherent mammalian cell monolayer formation on the insert membrane. Non-treated membrane inserts (some PC formats) are used for migration and invasion assays where cells in the apical chamber must actively migrate through the membrane pore to reach the basolateral side &mdash; a non-treated surface reduces passive cell adhesion that would produce false-positive migration signals. Transferability NEST Scientific cell culture inserts can be transferred from one plate to a fresh plate for media changes, cumulative secretion studies, and time-course experiments &mdash; a key advantage over the non-insert well format. Transfer the insert using sterile forceps or the insert flange. 
<h2 dir="ltr"> Specifications Context</h2>
 NEST Scientific cell culture inserts are manufactured from polystyrene with PET or PC membranes in TC-treated (vacuum plasma, contact angle &lt;10&deg;) or non-treated formats. Inserts are packed in individually sealed, peelable Tyvek film and blister packaging for sterility assurance &mdash; one plate per pack, sterile. E-beam sterilized to SAL 10⁻⁶; DNase/RNase-free and non-pyrogenic per lot. The insert flange geometry is designed to center the insert in the well, preventing membrane-wall contact and wicking. NEST Scientific cell culture inserts in PET and PC membranes across the four pore sizes (0.4, 1, 3, 8 &micro;m) and three plate formats (6-, 12-, 24-well) are available from MBP.

<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;

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.

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.

&nbsp;
<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.

<h2 data-section-id="1f93yys" data-start="914" data-end="963">How to Choose From All Centrifuge Tube Formats</h2>
&nbsp;
Volume and Rotor Compatibility
Selecting the correct tube size is essential for safe and efficient centrifugation. Microtubes ranging from 0.5&ndash;2 mL are designed for microcentrifuges, while 5&ndash;10 mL midi tubes fit compatible benchtop centrifuge rotors. Larger 15 mL and 50 mL conical tubes are commonly used in clinical and research centrifuges. Always verify rotor compatibility before introducing a new tube format into your workflow.
Sterility Requirements
For sensitive applications such as RNA extraction, cell culture, and clinical diagnostics, sterile tubes certified free of RNase, DNase, and pyrogens are recommended. Non-sterile tubes can provide a cost-effective solution for routine DNA analysis, protein assays, and general sample storage where sterility is not critical.
Material Selection
Polypropylene tubes offer excellent durability, can be autoclaved at 121 &deg;C, and resist many laboratory chemicals and solvents. Polystyrene tubes provide superior transparency, making it easier to monitor liquid levels and sample contents, although they are less resistant to heat and solvents.
Packaging and Inventory Planning
Microtubes are commonly available in pack sizes ranging from 500 to 1,000 units, while 15 mL and 50 mL conical tubes are often supplied in cases of 500. Laboratories with consistent usage may benefit from establishing recurring purchase orders to ensure uninterrupted supply.

<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.
