PCR Tube Racks

<h2 dir="ltr"> What Are PCR Tubes?</h2>
 PCR tubes are single-use, thin-wall polypropylene reaction vessels engineered for rapid, uniform heat transfer between the thermal cycler block and the PCR reaction. Wall thickness is typically 0.25&ndash;0.35 mm &mdash; thinner than standard microcentrifuge tubes &mdash; allowing the cycler's heating/cooling ramp rates to reach the sample faster and with greater uniformity. Use 0.2 mL tubes for standard cyclers and 0.1 mL tubes for fast-block or Rotor-Gene instruments.

<h2 dir="ltr"> How to Choose PCR Tubes</h2>
 Block Format: Standard vs Fast (Low-Profile) Standard 0.2 mL tubes are compatible with tall-block cyclers, including the Bio-Rad T100, Eppendorf Mastercycler EP, and Thermo Scientific SimpliAmp. Low-profile 0.1 mL tubes are required for fast-block instruments &mdash; Applied Biosystems StepOnePlus, Bio-Rad CFX96 Fast, and QIAGEN/Corbett Rotor-Gene &mdash; where the shallower well geometry accelerates thermal equilibration. Strip vs Individual Tube Format Individual tubes offer flexibility for small reaction sets and allow colour-coding by sample. 8-strip tubes speed up multichannel pipetting and reduce handling time when processing 8 or 16 samples per run. Corbett-style 4-strip tubes are the correct choice when running the QIAGEN Rotor-Gene instrument; standard 8-strip tubes do not fit its 72-well circular rotor. Cap Style Attached dome caps are sufficient for endpoint PCR. Attached flat caps or separately purchased optical caps are required for real-time qPCR fluorescence detection through the cap; dome caps attenuate fluorescence signal and should not be used with probe-based or SYBR-based qPCR when reading through the lid. Purity and Certification Specify tubes certified DNase-free, RNase-free, human DNA-free, and PCR inhibitor-free; independent lot-level testing is the quality standard. Tubes manufactured in cleanroom conditions (e.g., Class 100,000 equivalent) minimise particulate contamination risk. 
<h2 dir="ltr"> Specifications Context</h2>
 PCR tubes are manufactured from virgin polypropylene free of additives, dyes, and antistatic agents that could interfere with enzyme activity. Ultra-thin walls (0.25&ndash;0.35 mm) and transparent clarity facilitate visual inspection of the reaction volume. As of 2026, manufacturers including Axygen (Corning), SSI Bio, and Globe Scientific supply Corbett-compatible 4-strip formats widely distributed through North American channels. For tube rack accessories compatible with individual 0.2 mL and 0.5 mL tubes, see the PCR Tube Racks section within this category.

Storage Boxes & Racks

<h2 data-section-id="1hv97bw" data-start="0" data-end="47">What Are Laboratory Storage Boxes and Racks?</h2>
&nbsp;
Laboratory storage boxes and racks are essential organizational systems used to store, organize, and protect cryogenic vials, microcentrifuge tubes, centrifuge tubes, and microscope slides across freezers, cold rooms, and benchtop environments. Storage boxes are typically lidded, grid-based containers used for long-term sample organization in ultra-low temperature conditions, while racks are open-frame supports used for active handling during laboratory workflows such as pipetting, vortexing, and reaction setup.
Cryogenic storage boxes are commonly designed to hold 81 vials (9&times;9 format) or 100 vials (10&times;10 format), and are compatible with storage conditions ranging from &ndash;196 &deg;C in liquid nitrogen vapor phase to +121 &deg;C for autoclave sterilization (depending on material). Tube racks, on the other hand, provide stable upright positioning of tubes during active benchwork and are not primarily intended for long-term freezer storage.

<h2 data-section-id="flyrii" data-start="1159" data-end="1199">How to Choose Storage Boxes and Racks</h2>
&nbsp;
Vial Format and Capacity
The first selection criterion is compatibility with tube size and grid layout. The most common format is the 81-place (9&times;9) box designed for 1.0&ndash;2.0 mL cryovials. Smaller or specialized formats may accommodate 5 mL tubes or different vial diameters depending on grid spacing. Proper matching ensures secure fit, easy retrieval, and consistent sample organization in high-density storage systems.
Temperature Range
Material selection determines allowable storage conditions. Polycarbonate cryogenic boxes are the most versatile, supporting temperatures from liquid nitrogen levels (&ndash;196 &deg;C) through &ndash;80 &deg;C freezer storage and up to autoclave sterilization at +121 &deg;C. Cardboard freezer boxes with moisture-resistant coating are designed for economical freezer storage and can withstand ultra-low temperatures, but they are not suitable for autoclaving or long-term moisture exposure.
Tube Rack Materials and Use
Polypropylene racks are widely used because they are autoclavable and chemically resistant, making them suitable for sterile workflows. ABS and polystyrene racks provide lower-cost alternatives for general laboratory bench use but are not designed for autoclave conditions. For freezer organization, stainless steel racks are often used to hold multiple cryoboxes within &ndash;80 &deg;C upright freezer systems, improving accessibility and spatial organization.
Slide Storage Boxes
Microscope slide storage boxes are designed to protect standard 25 &times; 75 mm slides. They are available in 25-, 50-, and 100-slide capacities. Polypropylene versions are autoclavable and suitable for sterilized workflows, while fiberboard or ABS versions are typically used for room-temperature archival storage and transport.
Color Coding and Sample Identification
Color-coded storage boxes are widely used in biobanking and high-throughput laboratories to quickly differentiate sample groups without opening boxes or reading labels at freezer temperatures. Common systems include multiple lid colors paired with alphanumeric grids inside the box, enabling precise sample tracking and retrieval in large inventories.
&nbsp;
<h2 data-section-id="1jl751w" data-start="4067" data-end="4092">Specifications Context</h2>
&nbsp;
Modern polycarbonate cryogenic storage boxes are engineered for extreme temperature stability, typically rated from &ndash;196 &deg;C to +121 &deg;C, allowing use across liquid nitrogen vapor phase storage, &ndash;80 &deg;C freezers, and autoclave sterilization cycles. Cardboard freezer boxes are coated to resist moisture ingress and are optimized for cost-efficient high-density storage in ultra-low temperature environments.
The 81-place (9&times;9 grid) polycarbonate cryobox remains the standard format in most biorepositories and clinical research facilities due to its compatibility with SBS footprint freezer systems and automated inventory tracking workflows. These systems are widely used in genomics, cell banking, and pharmaceutical research environments.

<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. SP Bel-Art 96-well PCR racks and equivalent formats from Heathrow Scientific and Globe Scientific are widely distributed in North American research labs.&nbsp;

<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.

Microscope Accessories

<h2>What Are Microscope Accessories?</h2>
&nbsp;
Microscope accessories are supplementary components that configure, upgrade, or expand the function of a base microscope beyond its standard out-of-the-box specification. They fall into several categories: imaging accessories (cameras, camera adapters, camera relay lenses) for digital image capture and video documentation; optical accessories (additional or replacement objective lenses, eyepieces, auxiliary objectives for stereo microscopes) that change magnification or improve optical quality; fluorescence accessories (filter cube sets, LED fluorescence modules, mercury lamp adapters, UV/visible filter wheels) for adding or expanding fluorescence capability; stage accessories (multiwell plate holders, slide holders, cross-roller stages, motorized XY stage inserts, focus drives) that expand sample handling; illumination accessories (fiber optic illuminators, ring lights, polarizers, dark-field condensers) for alternative contrast methods; and maintenance and consumable accessories (immersion oil, lens paper, slide cleaning kits, replacement illuminator bulbs). Because accessory designs are instrument-specific (not all cameras, objectives, or stage inserts are universally compatible), identify the microscope model and manufacturer before ordering any accessory. Always identify the exact microscope model and manufacturer before ordering any accessory; thread standards, bayonet mounts, tube lengths, and connector formats vary significantly between brands and generations.

&nbsp;
<h2>How to Choose Microscope Accessories</h2>
&nbsp;
Digital cameras and adapters
Microscope cameras attach to the trinocular port (or monocular camera port on some models) via a C-mount camera adapter with an integrated relay lens. The relay lens magnification (typically 0.35x, 0.5x, or 1x) determines the effective field of view on the camera sensor. Choose a CMOS camera with 5 to 20 megapixels for brightfield documentation and routine fluorescence; scientific CMOS (sCMOS) or cooled CCD cameras for low-light fluorescence quantification. Confirm the camera software is compatible with the microscope's control software (if motorized).
Objective lenses
Replacement or additional objectives must match the microscope's objective thread standard and tube length (160 mm finite or infinity-corrected). Never mix finite-optics and infinity-corrected objectives on the same nosepiece; the image-forming properties are incompatible. Plan-apochromat objectives in the same brand family as the microscope are the safest choice for optical performance and parfocality with the existing objective set.
Fluorescence filter cube sets
Fluorescence filter cubes contain an excitation bandpass filter, a dichroic mirror, and an emission bandpass filter, which are the three components that define which fluorescent dye or protein is imaged. Common filter sets: DAPI (Ex 360/40, Di 400LP, Em 460/50); FITC/GFP (Ex 470/40, Di 495LP, Em 525/50); TRITC/mCherry (Ex 550/25, Di 565LP, Em 605/70); Cy5 (Ex 620/60, Di 660LP, Em 700/75). Confirm the cube block type (Olympus U-MF2, Nikon B-2A, Zeiss 38HE, or other) matches the filter cube turret of the specific microscope model.
Stage inserts and sample holders
Stage inserts expand sample compatibility: multiwell plate holders (96-well, 384-well, 6-well) for high-content imaging; glass-bottom dish holders for live-cell imaging with oil-immersion objectives; slide holder adapters for larger or smaller slide formats; and universal stage inserts for non-standard containers. Confirm the stage insert dimensions match the microscope's mechanical stage cutout and that the height profile is compatible with the condenser working distance for transmitted illumination.
LED fluorescence modules
LED fluorescence modules replace or augment mercury arc lamps in the fluorescence port of existing microscopes, providing individual LED channels for DAPI, GFP, TRITC, and Cy5 excitation. LED upgrades are available as bolt-on add-ons for many research-grade inverted and upright microscopes and significantly extend the fluorescence illumination service life from 200 to 300 hours (mercury) to 50,000+ hours (LED). Confirm the LED module's mounting standard and control interface (USB, TTL, or software-triggered) is compatible with the microscope.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Immersion oil for oil-immersion microscopy must match the refractive index for which the objective is designed; standard immersion oil has a refractive index of 1.515 at 23 degrees C (per ASTM and DIN standards). Using oils with different refractive indices introduces spherical aberration. Viscosity matters for the application: low-viscosity oils (Type A, 150 mPas) spread easily and are used for fast scanning; high-viscosity oils (Type B, 1250 mPas) resist creep at elevated stage temperatures. Clean all residual immersion oil from objectives immediately after each use with lens tissue dampened with appropriate lens cleaning solution; dried immersion oil is difficult to remove and can permanently damage the objective coating.&nbsp;

Cryogenic Vials

<h2>What Are Cryogenic Vials?</h2>
&nbsp;
Cryogenic vials are specialized screw-cap laboratory containers manufactured from cryogenic-grade virgin polypropylene (PP) and designed to withstand extreme temperatures ranging from &minus;196&deg;C in liquid nitrogen storage to +121&deg;C during steam autoclaving. They serve as the primary storage vessel for biological materials requiring long-term preservation, including cell lines, serum, plasma, blood samples, DNA, RNA, microbial cultures, and other biospecimens. Common vial capacities include 1.2 mL, 1.5 mL, 1.8 mL, 2 mL, 3 mL, and 5 mL, with the 2 mL format being the most widely used standard for cell culture and biobanking applications. Most cryogenic vials feature leak-resistant screw caps with silicone sealing gaskets and dedicated writing areas for sample identification. For storage in liquid nitrogen, it is important to use vials specifically certified for cryogenic applications, as standard laboratory tubes are not designed to tolerate temperatures as low as &minus;196&deg;C.

<h2>How to Choose Cryogenic Vials</h2>
&nbsp;
Thread Type: Internal vs. External
Thread design influences both contamination control and workflow compatibility. Internal-thread vials position the sealing mechanism inside the neck of the vial, reducing the external surface area exposed to contaminants and making them a common choice for cell culture and biosafety-sensitive applications. External-thread vials place the threads on the outside of the vial neck, maximizing internal storage volume and improving compatibility with automated capping, decapping, and robotic handling systems. Laboratories using automated biobanking workflows often prefer external-thread formats.
Volume Selection
Vial capacity should match the intended sample type and storage requirements. The 1.8&ndash;2.0 mL size is commonly used for cell lines, serum aliquots, and general biospecimen storage because it fits standard cryogenic storage boxes. Smaller 1.2 mL formats support high-density storage of limited-volume samples, while larger 3&ndash;5 mL vials are suitable for tissue specimens, bacterial glycerol stocks, and applications requiring larger sample volumes.
Sterility and Purity Certification
For cell culture, molecular biology, and clinical research applications, cryogenic vials should be supplied with certifications confirming they are RNase-free, DNase-free, non-pyrogenic, and endotoxin-free. Many laboratories also prefer gamma-sterilized vials, which reduce contamination risk and eliminate the need for additional sterilization before use. Traceable lot documentation and certificates of conformity are often required in regulated environments.
Self-Standing vs. Round Bottom Designs
Self-standing cryogenic vials feature a molded base that allows them to remain upright on laboratory benches without additional support, reducing the risk of spills during sample handling. Round-bottom designs are compatible with a broader range of storage racks and cryogenic systems but generally require a rack or holder during bench-top use. The choice largely depends on laboratory workflow and storage equipment.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Cryogenic vials are typically manufactured from high-purity polypropylene because of its excellent durability and resistance to ultra-low temperatures. Products intended for liquid nitrogen immersion should carry explicit certification for liquid-phase storage, as some vials are approved only for vapor-phase applications. Vial dimensions, particularly outer diameter, determine compatibility with freezer boxes, racks, and automated storage systems, so measurements should be confirmed before mixing products from different manufacturers. Modern biobanking facilities increasingly use externally threaded, 2D-barcoded cryogenic vials integrated with laboratory information management systems (LIMS) to improve inventory tracking, sample traceability, and large-scale repository management.

Test Tubes

<h2 dir="ltr">What are Test Tubes?</h2>
 Test tubes for laboratory use are open-ended, cylindrical glass or plastic tubes used to hold, mix, incubate, and heat liquid and solid samples across a broad range of applications: bacteriological culture, tissue culture, clinical chemistry, serological assays, immunology, and general sample processing. Choose borosilicate glass for reusable, high-temperature, or chemically demanding applications; choose polystyrene disposable 12&times;75 mm tubes for flow cytometry and colorimetric assays; choose polypropylene capped tubes for microbial culture with anaerobic or gas-generating organisms.

<h2 dir="ltr">How to Choose Test Tubes</h2>
 Material: Glass vs. Polypropylene vs. Polystyrene Borosilicate glass 3.3 (ASTM E438 Type I, Class B) test tubes withstand direct flame, autoclave sterilization at 121 &deg;C, and most solvents, acids, and bases. They are reusable and autoclavable, making them cost-effective over high-volume laboratory runs. Polystyrene (PS) disposable tubes offer outstanding optical clarity for flow cytometry (FACS), cell counting, and OD-based colorimetric assays, but cannot be autoclaved and should not be used with aromatic solvents or strong acids. Polypropylene (PP) tubes are chemically resistant, autoclavable, and available with screw caps for anaerobic culture or gas-generating reactions. Rimmed vs. Rimless Rimless test tubes (fire-polished ends) allow easier insertion of rubber or silicone stoppers and are preferred for plugging with cotton wool for microbial culture. Rimmed tubes have a flared lip that facilitates pouring and is compatible with spring-metal tube closures. Confirm your closure type before ordering in bulk. Size and Volume The most common test tube dimensions in clinical and research labs: 12&times;75 mm: ~5 mL capacity; standard for flow cytometry, FACS, serology 13&times;100 mm: ~10 mL; general culture and chemistry 16&times;100 mm: ~14 mL; culture and chemistry 16&times;125 mm: ~17 mL; microbiological culture 18&times;150 mm: ~25 mL; larger-volume digests and culture Wall thickness of 1.2 mm (light wall, borosilicate 3.3) is the standard for general lab use; heavy-wall versions are used for digestions and applications involving vacuum or pressure. Sterile vs. Non-Sterile Sterile borosilicate glass culture tubes (individually wrapped or bulk-sterilized) are required for microbial culture, cell culture, and any application where contamination would invalidate the result. Non-sterile tubes are adequate for chemistry, spectroscopy, and other abiotic applications. Disposable PS tubes from Corning (PYREX&trade;) and Globe Scientific are supplied sterile or non-sterile; confirm the specification on the lot certificate. 
<h2 dir="ltr"> Specifications Context</h2>
 Borosilicate glass 3.3 test tubes have a linear thermal expansion coefficient of 3.3 &times; 10⁻⁶ K⁻&sup1;, providing resistance to thermal shock from room temperature to 300 &deg;C (direct flame) and from 0 to 121 &deg;C (autoclave cycles). Light-wall tubes (1.2 mm uniform wall thickness) provide the standard for general laboratory use; heavy-wall variants (2.0 mm) are used for digestion vessels and pressurized applications. Corning PYREX&trade; disposable round-bottom rimless glass tubes for tissue culture conform to ASTM standards and are the reference format for bacteriological serology and cell wash procedures.

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;
