Cold Storage Coolers & Chillers

<h2 data-section-id="16gwf6l" data-start="0" data-end="46">What Are Cold Storage Coolers and Chillers?</h2>
&nbsp;
Laboratory cold storage coolers and chillers are bench-top temperature-control systems designed to keep temperature-sensitive reagents, enzymes, antibodies, cells, and biological samples cold during active laboratory work. They maintain low temperatures&mdash;typically around 0 &deg;C or below freezing&mdash;without requiring ice, electricity (in passive systems), or immediate access to a freezer. These systems are widely used in molecular biology, PCR setup, nucleic acid extraction, enzyme handling, and cell-based assays where maintaining cold-chain conditions during pipetting and multi-step workflows is essential.
Gel-based benchtop coolers are the most common type. They are pre-frozen at approximately &ndash;20 &deg;C and use phase-change materials to maintain samples near 0 &deg;C for several hours, typically up to four hours depending on ambient conditions. This provides a clean, stable, and consistent cooling environment without melting ice or water contamination.

&nbsp;
Tube Format Compatibility
Coolers and chillers are designed around specific laboratory tube formats. Common configurations include holders for 0.2 mL PCR tubes and strips, 1.5/2.0 mL microcentrifuge tubes, 15 mL conical tubes, and 50 mL conical tubes. Some dual-sided designs combine multiple formats in a single unit, allowing simultaneous use for PCR plates on one side and microtubes on the other, improving workflow efficiency and reducing bench clutter.
Temperature Hold and Duration
Passive gel-based coolers maintain approximately 0 &deg;C for several hours after being pre-chilled at &ndash;20 &deg;C. Their performance depends on ambient temperature, workload, and sample frequency. Metal cooling blocks pre-chilled at &ndash;80 &deg;C can achieve lower temperatures temporarily but warm more quickly. For workflows requiring long-duration or continuously controlled cooling, electrically powered thermoelectric chillers provide stable setpoints over extended periods.
Ice-Free vs Ice-Based Systems
Gel-based coolers eliminate the need for ice entirely, reducing condensation, contamination risk, and constant ice replenishment during experiments. Traditional ice buckets remain a low-cost option but require continuous maintenance and can introduce water exposure risks. Ice-free systems are preferred in workflows where moisture control and consistent temperature stability are critical.
Single-Sided vs Dual-Sided Designs
Single-sided coolers are suitable for workflows using one tube format consistently. Dual-sided coolers accommodate multiple formats&mdash;such as PCR plates and microtubes&mdash;within a single unit, making them more versatile for complex molecular biology workflows. Selection depends on workspace constraints and experimental diversity.
Dry Ice Compatibility
Some insulated cold storage systems are designed for use with dry ice, maintaining extremely low temperatures around &ndash;78 &deg;C. These are used for short-term cryogenic handling, transport, or dispensing workflows where ultra-low temperature maintenance is required without active refrigeration.
&nbsp;
<h2 data-section-id="1jl751w" data-start="3892" data-end="3917">Specifications Context</h2>
&nbsp;
Modern gel-based benchtop coolers are engineered using phase-change materials that stabilize near 0 &deg;C for several hours after being pre-conditioned at &ndash;20 &deg;C. Dual-format systems have become increasingly common in molecular biology laboratories because they reduce the number of separate cooling devices required on the bench. As of 2026, these ice-free systems are widely adopted in PCR and nucleic acid workflows due to their consistency, cleanliness, and ease of use compared to traditional ice-based cooling methods.

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.

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.

Rollers & Rotators

<h2>What are tube rollers and rotators?</h2>
&nbsp;
Tube rollers and rotators are low-speed mixing instruments that provide gentle, continuous agitation of tubes and bottles through rolling or inversion motion rather than high-speed shaking. A tube roller operates by rotating horizontal rollers that the tubes or bottles rest on, causing them to roll along their long axis in place, creating slow, even mixing of the tube contents without introducing air bubbles. A rotator (end-over-end mixer) clamps tubes in a wheel or drum that rotates at 5&ndash;30 rpm, inverting the tubes repeatedly through a full circle for thorough but gentle mixing.

<h2>How to choose rollers and rotators</h2>
&nbsp;
Choose a tube roller for blood collection and clinical tube mixing
Tube rollers are the standard instrument for homogenizing anticoagulated blood collection tubes before clinical testing, operating at 5&ndash;20 rpm to ensure even mixing of blood and anticoagulant without hemolysis from excessive speed. The roller format also suits other tubes and bottles that are too long for end-over-end rotation to work effectively in the space available.
Choose a rotator for antibody-bead incubations and immunoprecipitation
End-over-end rotators invert tubes through a full 360&deg; cycle, ensuring that beads settled at the tube bottom are continuously resuspended and that the bead surface is uniformly exposed to the solution throughout the incubation. This complete inversion is essential for immunoprecipitation, pull-down assays, and antibody-coupling incubations where beads must stay in suspension for efficient binding.
Consider the tube capacity and format each instrument accommodates
Tube rollers hold a fixed number of tubes of defined diameter on the roller surface; rotator wheels typically accommodate a defined set of tube positions for specific tube formats. Confirm that the instrument handles the tube diameter, length, and quantity you work with most commonly, and that accessories are available to accommodate additional formats.
Evaluate speed range against your mixing requirement
Blood sample homogenization requires gentle speed of 5&ndash;12 rpm to avoid hemolysis, while antibody-bead incubations can use faster rotation of 10&ndash;30 rpm for more active suspension maintenance. A variable-speed rotator provides flexibility across applications; a fixed-speed roller set at the correct blood mixing speed is adequate for dedicated blood handling.
Confirm whether incubator-compatible models are needed for your workflow
Rotator and roller incubations often require 37&deg;C for antibody binding or hybridization reactions. Models designed for incubator interior use have compact profiles and materials that tolerate incubator humidity and temperature, while standard bench models are not always rated for this environment.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Tube rollers used for blood sample mixing are typically operated at a fixed or low-speed range of 5&ndash;12 rpm, a range established from clinical literature showing that this rotation speed adequately homogenizes anticoagulated blood without inducing hemolysis from mechanical stress. As of 2026, compact benchtop tube rollers that fit inside standard incubators and cold rooms without taking up significant shelf space remain popular in clinical and research labs for routine sample preparation.

Inverted Microscopes

<h2>What Are Inverted Microscopes?</h2>
&nbsp;
An inverted microscope is a compound light microscope in which the objective lens is positioned below the specimen stage, pointing upward, while the illumination system (condenser and light source) is above the stage, pointing downward. This inverted configuration allows cells growing on the inner floor of a culture dish, flask, or well plate to be observed directly through the clear plastic or glass base without removing the vessel lid and without disturbing the sterile culture. By contrast, upright microscopes require samples to be mounted on glass slides and covered with a coverslip for observation. Inverted microscopes are the universal tool for cell biology research; any workflow involving adherent mammalian cells, suspension cultures, organoids, embryos, or zebrafish in standard tissue culture vessels requires an inverted microscope for routine monitoring. Key contrast methods for live-cell observation are phase contrast (for unstained cells, the standard for assessing cell health, morphology, and confluency) and differential interference contrast (DIC, for optical sectioning). Fluorescence epi-illumination is added via a fluorescence port and filter cube turret for imaging GFP-labeled proteins, immunofluorescence-stained cells, or nuclear dyes such as DAPI. An inverted microscope is required for any workflow where cells are observed in their growth vessel (culture dishes, T-flasks, well plates, or spinner flasks). Phase contrast is non-negotiable for routine cell health monitoring; add fluorescence for reporter protein or immunofluorescence imaging.

&nbsp;
<h2>How to Choose an Inverted Microscope</h2>
&nbsp;
Routine cell culture vs. research imaging
Routine cell culture microscopes prioritize phase contrast imaging, compact footprint, ease of use, and affordability; they are workhorses placed in biosafety cabinet rooms for daily culture monitoring. Research inverted microscopes add motorized stage and focus control, multi-channel LED fluorescence, automated XY scanning for multiwell plate imaging, programmable time-lapse, and software-controlled imaging modules for confocal, TIRF, and FRET; suited to imaging-centric research labs.
Phase contrast system
Phase contrast requires a matched pair of a phase objective and annular phase ring in the condenser. Low-contrast (PhI or Ph1) phase rings pair with low-power objectives (4x, 10x) for overview; medium-contrast (PhII or Ph2) rings pair with 20x and 40x objectives for standard cell morphology; high-contrast (PhIII or Ph3) rings pair with 60x or 100x oil-immersion objectives for high-magnification phase work. Confirm that the phase ring set installed in the condenser matches the objective phase designation for each magnification in use; mismatched pairs produce halos around cells rather than flat-field phase contrast.
Fluorescence: LED vs. mercury arc lamp
LED fluorescence illumination (available as an upgrade or built-in on most current inverted microscopes) provides 50,000+ hour lamp lifetime, instant-on/off switching (eliminating the warm-up and cool-down delays of mercury lamps), channel switching in less than 100 milliseconds for rapid multi-color imaging, and no mercury disposal requirement. Mercury arc lamps (HBO 50 or HBO 100) provide higher peak UV output for DAPI and Hoechst imaging, where LED UV intensity may be limiting, but require lamp replacement every 200 to 300 hours and strict mercury waste handling. For new purchases, LED fluorescence systems are the standard recommendation.
Objective working distance and culture vessel compatibility
Inverted microscope objective working distance (the distance from the front lens to the focused specimen) must exceed the thickness of the culture vessel base. Standard tissue culture polystyrene (PS) has a base thickness of 1 to 1.2 mm; glass-bottom dishes have 0.17 mm (No. 1.5 coverglass). Objectives specified for plastic culture vessels (abbreviated ELWD or LLWD) correct for the optical aberrations introduced by thick plastic and provide adequate working distance. Standard oil-immersion objectives are designed for No. 1.5 coverglass (0.17 mm) and cannot image through standard tissue culture plastic at high quality without significant spherical aberration.
Stage and sample holder
Confirm that the inverted microscope's stage accommodates your culture vessels: standard 35 mm and 60 mm culture dishes, T-25 and T-75 flasks, 6-well, 12-well, 24-well, 96-well, and 384-well plates. Universal stage holders with adjustable guides are available for most platforms; dedicated plate holders for 96-well and 384-well plates are used for high-content imaging applications. Motorized XY stages with encoder feedback are required for automated multiwell plate scanning and time-lapse experiments.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
For time-lapse live-cell imaging, focus drift over extended runs (hours to days) is the principal challenge; motorized focus with hardware autofocus maintains focus independent of thermal drift. Camera sensor size and pixel size determine the field of view at each magnification; a larger sensor captures a wider field per image, reducing the number of positions needed to tile a full well. For drug screening and plate-based assays, confirm that the software can drive the XY stage through a defined grid pattern and export images in a format compatible with your image analysis pipeline.

Compound Microscopes

<h2>What Are Compound Microscopes?</h2>
&nbsp;
A compound microscope forms a magnified image through two sequential lens systems: the objective lens (positioned close to the specimen) provides the primary magnification; the eyepiece (ocular) lens further magnifies the image from the objective, producing a final image that the eye or camera receives. Magnification is the product of the objective magnification and the eyepiece magnification (e.g., 40x objective x 10x eyepiece = 400x total). The transmitted light illumination system (Koehler illumination) passes light from below through the thin specimen mounted on a glass slide, through the objective, and to the eyepiece. This optical configuration provides the highest resolving power of any routine light microscope type, with resolution determined by the numerical aperture (NA) of the objective and the wavelength of light used. Routine brightfield compound microscopes with 4x, 10x, 40x, and 100x (oil) objectives and 10x eyepieces cover 40x to 1000x total magnification. Phase contrast models add a phase ring in the condenser matched to each objective, enabling contrast of unstained transparent cells. Fluorescence models add an epi-fluorescence port and filter cube turret for imaging immunofluorescence-labeled sections and fluorescent markers. Choose a compound microscope for examination of specimens that have been prepared as thin slides, stained sections, or smears; it is the standard instrument for histology, clinical microbiology, hematology, and fixed-tissue fluorescence imaging.

<h2>How to Choose a Compound Microscope</h2>
&nbsp;
Brightfield vs. phase contrast vs. fluorescence
Brightfield compound microscopes are the entry-level configuration, adequate for stained tissue sections, Gram-stained bacterial smears, blood smears, and all applications where contrast comes from staining rather than optical manipulation. Phase contrast is required for observation of unstained, living, or lightly fixed cells, where inherent contrast is too low for brightfield, common in microbiology, parasitology, and cytology. Fluorescence (epi-fluorescence) is required for DAPI nuclear staining, immunofluorescence (IF) labeling, FISH assays, and fluorescent reporter protein imaging in fixed cells.
Objective quality: plan-achromat vs. plan-apochromat
Plan-achromat objectives correct for chromatic aberration at two wavelengths and are flat (plan) across the field, suitable for routine brightfield and basic fluorescence imaging. Plan-apochromat objectives correct for chromatic aberration at three or more wavelengths and provide superior color fidelity and fluorescence flatness across the full field, required for multi-channel fluorescence imaging, quantitative image analysis, and publication-quality fluorescence documentation. Plan-apochromat sets cost significantly more than plan-achromat sets; specify them when fluorescence image quality and accurate color reproduction matter.
Magnification set
A standard objective set for a research compound microscope: 4x (NA 0.10) for tissue overview; 10x (NA 0.30) for histological pattern assessment; 20x (NA 0.50) for cellular detail without immersion; 40x dry (NA 0.65 to 0.75) for detailed cell morphology; 63x or 100x oil immersion (NA 1.25 to 1.40) for highest-resolution organelle imaging and bacteria identification. For clinical microbiology, 100x oil is the standard for bacterial identification. For routine histology, 10x and 40x are the most used.
Illumination: LED vs. halogen
LED transmitted light illumination is now standard on most new compound microscopes, providing 50,000+ hour lamp life, instant-on operation, no color temperature shift over lifetime, and significantly lower power consumption than halogen. Halogen (6V 30W or 12V 100W) remains in use on older instruments and some entry-level models and requires bulb replacement every 50 to 200 hours. For new purchases, specify LED illumination.
Camera port and documentation
A trinocular head with a C-mount camera port is standard for documentation in research labs. The camera beam splitter on research-grade microscopes maintains eyepiece brightness while splitting a portion of the light to the camera; entry-level trinoculars may dim the eyepiece view when the camera port is in use. A CMOS or CCD camera is required; confirm the camera's pixel size against the objective magnification and required image resolution for your intended analysis.

<h2>Specifications Context</h2>
&nbsp;
Oil immersion objectives (63x NA 1.40, 100x NA 1.40) require immersion oil between the objective front lens and the coverslip to achieve their rated NA. Confirm that the coverslip thickness is No. 1.5 (0.17 mm); most plan-apochromat objectives are corrected for this standard thickness. Non-standard coverslip thickness introduces spherical aberration that degrades resolution and fluorescence image quality. For routine use in clinical microbiology or hematology where high-throughput slide processing is needed, wide-field eyepieces (22 mm field number) reduce the number of microscope fields needed to survey the full slide area, improving throughput.&nbsp;

Cryogenic Labels

<h2 dir="ltr"> What Are Cryogenic Labels?</h2>
 Cryogenic labels are adhesive identification labels engineered to maintain adhesion, legibility, and dimensional stability across the full temperature range encountered in biopreservation workflows: from frozen-surface application at &minus;80 &deg;C to long-term storage in liquid nitrogen at &minus;196 &deg;C, through transport on dry ice, and back to room-temperature processing. Standard office or general-purpose labels fail at &minus;20 &deg;C; cryogenic adhesives are acrylic-based formulations that remain pliable and adhesive down to &minus;196 &deg;C. Related product families include thermal labels, labeling tape, and tape dispensers for broader lab identification needs. For any biological sample stored below &minus;20 &deg;C, a cryogenic-rated label with verified adhesion specs is required to ensure sample traceability.

<h2 dir="ltr"> How to Choose Cryogenic Labels</h2>
 Storage Temperature Range Confirm whether samples will be stored in LN₂ liquid phase (&minus;196 &deg;C), LN₂ vapor phase (&minus;150 &deg;C), &minus;80 &deg;C deep-freeze, or &minus;20 &deg;C freezer. Labels rated to &minus;196 &deg;C are suitable for all tiers; labels rated only to &minus;80 &deg;C cost less but cannot be used in LN₂ tanks. Print Technology: Direct-Thermal vs. Thermal-Transfer Direct-thermal cryo labels print without a ribbon (compatible with Zebra, DYMO, Brady direct-thermal printers) and are convenient for on-demand printing in lower-volume workflows. Thermal-transfer cryo labels use a resin ribbon to achieve sharper barcodes, chemical resistance (ethanol immersion up to 15 minutes, xylene up to 30 minutes), and temperature resistance up to +100 &deg;C &mdash; required for GLP/GMP chain-of-custody documentation. Application to Frozen vs. Ambient Surfaces Standard cryo labels must be applied at room temperature before freezing. Specialized frozen-surface labels (often called CryoSTUCK or equivalent) bond directly to vials at &minus;80 &deg;C without thawing &mdash; critical for re-labeling biobanked specimens without compromising viability. Container Size and Shape Labels must match the container geometry: cryo vials and microtubes require wrap-around labels with &ge;6 mm overlap for adhesion on curved surfaces. PCR plates use sidewall or end-cap labels. Freezer boxes use flat larger-format labels. Confirm dimensions before purchasing a roll. Permanent vs. Removable Adhesive Permanent cryogenic adhesive is standard for long-term biopreservation &mdash; it will not migrate or detach under repeated freeze-thaw cycling. Removable cryo adhesives are available for temporary sample identification that may need relabeling. 
<h2 dir="ltr"> Specifications Context</h2>
 Cryogenic label polyester facestocks are typically 50&ndash;100 &micro;m thick and dimensionally stable across the &minus;196 &deg;C to +100 &deg;C range. Acrylic-based cryogenic adhesives maintain &ge;2 N/25 mm peel strength at &minus;80 &deg;C on polypropylene cryo vials (typical manufacturer-verified spec). Label rolls are supplied on 1-inch or 3-inch cores, 250&ndash;1,000 labels per roll depending on label size.&nbsp;&nbsp;

Thermal Labels

<h2 dir="ltr">What Are Laboratory Thermal Labels?</h2>
 Laboratory thermal labels are adhesive labels designed for printing by direct-thermal or thermal-transfer desktop label printers &mdash; the two print technologies used for barcode and specimen ID generation in research, clinical, and diagnostic labs. Direct-thermal labels activate a heat-sensitive coating to produce an image without ink or ribbon; thermal-transfer labels use a resin or wax ribbon to fuse ink into the label surface. Thermal labels cover a wide range of container types: cryo vials, microcentrifuge tubes, PCR strips, 15/50 mL conicals, microscope slides, and specimen collection bags. Choose thermal-transfer labels for any sample requiring chemical resistance, temperatures above +50 &deg;C, or long-term barcode legibility; choose direct-thermal for low-cost, short-to-medium-term applications.

<h2 dir="ltr"> How to Choose Laboratory Thermal Labels</h2>
 Print Technology Compatibility Confirm whether the printer is direct-thermal (no ribbon required, e.g., Zebra GK420d, DYMO LabelWriter) or thermal-transfer (ribbon required, e.g., Zebra ZT230, Datamax M-Class). The two label types are not interchangeable &mdash; a thermal-transfer label will not print correctly in a direct-thermal printer and vice versa. Temperature and Chemical Exposure Direct-thermal label coatings degrade above approximately 50&ndash;60 &deg;C and with prolonged UV exposure, limiting their use to room-temperature and short-term cold storage applications. Thermal-transfer labels with a resin ribbon produce output resistant to temperatures up to +100 &deg;C, ethanol, xylene, and sanitizing wipes &mdash; required for autoclave tracking, histology, and GLP-regulated sample management. Container and Size Match Label dimensions must match the printable area of the label and the geometry of the container. Common lab thermal label widths are 0.5&ndash;2 inches; lengths are 0.25&ndash;3 inches. Verify dimensions against the container's flat-printable surface, accounting for any wrap-around on curved vials. Roll Core and Printer Compatibility Standard roll cores are 1-inch inner diameter for compact desktop printers; 3-inch cores fit high-volume industrial label printers. Confirm the printer's maximum roll diameter and label width capability before selecting roll format. Material: Paper vs. Polyester Paper-based thermal labels cost less and are suitable for ambient-temperature, short-duration applications (reagent dating, sample intake). Polyester thermal labels are moisture-resistant, more tear-resistant, and rated for demanding environments including freezers and chemical splash &mdash; specified for long-term specimen tracking and any application where label durability is a safety or compliance requirement. 
<h2 dir="ltr"> Specifications Context</h2>
 Direct-thermal label paper weight is typically 58&ndash;80 g/m&sup2;; polyester variants are 50&ndash;100 &micro;m thick. Standard roll dimensions are 2.25 inches &times; 1.25 inches (common for specimen tubes) and 4 inches &times; 6 inches (common for shipping and larger specimen bags). Print resolution for lab barcode labels should be 300 dpi for 1D/2D barcodes on labels smaller than 1 inch &times; 0.5 inch &mdash; 203 dpi produces legible output on larger-format labels.&nbsp;
