Transfer Pipettes

<h2>What are disposable transfer pipettes?</h2>
&nbsp;
Disposable transfer pipettes are single-use plastic liquid-handling tools made from low-density polyethylene (LDPE). They are designed as a one-piece bulb-and-stem system used for transferring, dispensing, and handling small volumes of liquids in laboratory workflows.
They are commonly used as a safer and more convenient alternative to glass Pasteur pipettes. Being plastic and disposable, they eliminate the risk of breakage, reduce cross-contamination, and remove the need for separate rubber bulbs. The flexible bulb allows controlled aspiration and dispensing of reagents, samples, and solutions.

<li>Disposable Pasteur pipettes &ndash; for general single-use liquid handling</li>
</ul>
&nbsp;
<h2>How to choose transfer pipettes</h2>
&nbsp;
Tip style Fine-tip pipettes are used for precise work such as microplate spotting and small-volume handling. Standard tips are suitable for general transfers, while wide-bore designs are better for viscous liquids or blood samples. Longer stems help access deep containers.
Capacity and volume handling Select pipettes based on typical working volumes. Smaller pipettes are suitable for low-volume transfers, while larger ones are used for routine sample handling. The effective draw volume depends on bulb capacity and usage technique.
Graduated vs non-graduated Graduated pipettes allow approximate volume estimation and are useful in clinical and diagnostic workflows. Non-graduated pipettes are intended for general dispensing where precise measurement is not required.
Sterility requirements Sterile pipettes are used in microbiology, cell culture, and clinical applications where contamination control is essential. Non-sterile versions are suitable for general laboratory and teaching use.
Length and accessibility Long pipettes are preferred for deep vessels such as flasks and bottles, while shorter designs are used for compact tubes and small workspaces.
&nbsp;

Wide Mouth Bottles

<h2 data-section-id="dscteu" data-start="0" data-end="42">What Are Wide Mouth Laboratory Bottles?</h2>
&nbsp;
Wide-mouth laboratory bottles are storage containers designed with a broad neck opening, typically ranging from 38 mm to 63 mm in diameter, allowing easy filling, dispensing, and cleaning. Their large opening makes them ideal for handling powders, granules, viscous liquids, biological samples, and other materials that are difficult to transfer through narrow-neck containers. Globe Scientific Diamond RealSeal wide-mouth bottles are available in several materials, including HDPE, polypropylene (PP), LDPE, and PETG, each suited to different laboratory applications. HDPE bottles offer excellent chemical resistance and low-temperature performance, PP bottles provide autoclavability, LDPE bottles offer flexibility, and PETG bottles are commonly used for sterile media storage. For laboratories requiring maximum storage efficiency and sterilization capability, PP square wide-mouth bottles are often the preferred option because they are autoclavable and utilize shelf space more effectively than round bottles.

&nbsp;
Round vs. Square Design
Round wide-mouth bottles are the traditional laboratory format and fit easily into standard storage racks and holders. Their curved interior walls help reduce material retention during dispensing and cleaning. Square bottles maximize storage efficiency by reducing unused space between containers on shelves and inside refrigerators. They also provide flat surfaces for labels, making identification easier and improving label adhesion. Laboratories managing large inventories often favor square bottles for their superior space utilization.
Material and Temperature Requirements
HDPE wide-mouth bottles are suitable for general-purpose chemical, reagent, and sample storage. They offer broad chemical compatibility and can be used in low-temperature environments, including standard laboratory freezers and many ultra-low temperature applications. Polypropylene wide-mouth bottles are the preferred choice when sterilization is required, as they can be autoclaved at 121&deg;C without deformation. LDPE bottles provide flexibility and are useful when gentle squeezing or easy handling is beneficial, although they are not intended for autoclaving. PETG bottles combine excellent clarity with durability and are commonly selected for sterile media preparation and storage.
Amber Bottles for Light-Sensitive Materials
Amber wide-mouth bottles help protect photosensitive materials from UV and visible light exposure. They are commonly used for storing light-sensitive powders, chemicals, biological reagents, and pharmaceutical compounds. When long-term light protection is required, amber HDPE bottles provide an effective and economical storage solution.
Volume Selection
Smaller bottles in the 30&ndash;60 mL range are ideal for standards, reference materials, and small sample aliquots. Mid-size bottles between 125 mL and 500 mL are commonly used for working reagents, buffers, and routine laboratory materials. Larger bottles ranging from 1 L to 2 L are suitable for bulk powders, stock solutions, and frequently accessed laboratory reagents.

Wash Bottles

<h2 data-section-id="gy6c1g" data-start="0" data-end="42">What Are Laboratory Wash Mouth Bottles?</h2>
&nbsp;
Laboratory wash bottles, also known as squeeze bottles or wash mouth bottles, are flexible LDPE containers available in 250 mL, 500 mL, and 1000 mL capacities. They feature a narrow dispensing nozzle or integrated draw-tube spout that delivers a controlled stream of liquid when the bottle is squeezed by hand. The flexibility of LDPE enables this dispensing action, making it the preferred material for wash bottles. These bottles are commonly used for rinsing laboratory glassware with distilled or deionized water, dispensing solvents during sample preparation, flushing residues during titrations and extractions, and directing liquids into narrow-neck vessels. Globe Scientific wash bottles are available with color-coded polypropylene caps and GHS-labeled safety-vented options for handling volatile solvents. Safety-vented wash bottles should always be used with volatile solvents such as ethanol, methanol, isopropanol, and acetone to prevent pressure build-up caused by vapor expansion.

&nbsp;
Vented vs. Non-Vented
Non-vented wash bottles are suitable for deionized water, distilled water, and other non-volatile aqueous solutions. Safety-vented wash bottles include a pressure-relief vent in the dispensing nozzle, allowing solvent vapors to escape safely and reducing the risk of pressure accumulation. These bottles are recommended for volatile solvents such as ethanol, methanol, isopropanol, and acetone. Globe Scientific GHS-labeled wash bottles combine safety venting with pre-printed hazard labeling for improved chemical identification and compliance.
Color-Coded Cap System
Color-coded caps help prevent reagent mix-ups in busy laboratory environments. A commonly used convention is blue for water, red for ethanol, yellow for isopropanol, green for methanol, and white for custom labeling or general use. Establishing a consistent color-coding system throughout the laboratory helps improve safety and workflow efficiency.
Wide Mouth vs. Standard Design
Standard wash bottles use a narrow draw tube extending to the base of the bottle, allowing liquid dispensing while the bottle remains upright. Wide-mouth wash bottles feature a larger neck opening, making refilling from bulk containers, carboys, or reagent bottles faster and easier. Laboratories that refill bottles frequently often prefer wide-mouth designs to reduce spills and simplify handling.
Volume Selection
The 500 mL wash bottle is the most common laboratory size, providing a balance between capacity and ease of handling. A 250 mL bottle is ideal when smaller volumes are sufficient or greater dispensing control is required. For high-throughput environments where liquids are used continuously, 1000 mL bottles minimize refill frequency and improve efficiency.

Cryo Boxes

<h2>What Are Cryo Boxes?</h2>
&nbsp;
Cryo boxes are lidded, gridded storage containers designed to organize cryogenic vials, microcentrifuge tubes, and centrifuge tubes inside ultra-low temperature (ULT) freezers at &minus;80&deg;C, vapor-phase liquid nitrogen refrigerators (&minus;150 to &minus;190&deg;C), and cryogenic dewars. The two primary materials are water-resistant coated cardboard (economical, single-use) and rigid polycarbonate or polypropylene (reusable, autoclavable, transparent). Standard well configurations&mdash;25 (5&times;5), 81 (9&times;9), and 100 (10&times;10)&mdash;in 2-inch and 3-inch box heights match common cryogenic vial sizes. The alphanumeric grid on the lid helps with sample tracking in LIMS systems. Cardboard cryo boxes are vapor-phase LN2 rated only; polycarbonate is required for autoclave use or liquid-phase LN2 immersion.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
&bull; Standard cryo boxes for cryogenic vial storage &bull; Freezer storage boxes for ultra low temperature use &bull; Cardboard cryo boxes for cost effective storage &bull; Polypropylene cryo boxes for durability and reuse &bull; Grid format boxes for easy sample organization &bull; Hinged lid cryo boxes for quick access &bull; Color coded storage boxes for sample identification &bull; Cryo storage boxes for 1.5 mL and 2.0 mL vials
&nbsp;
<h2>How to Choose Cryo Boxes</h2>
&nbsp;
Material: Cardboard vs. Polycarbonate vs. Polypropylene
Cardboard cryo boxes are economical and used for long-term storage at &minus;80&deg;C or vapor-phase LN2. They are single-use and not autoclavable. Polycarbonate (PC) boxes are durable, transparent, and autoclavable at 121&deg;C, making them suitable for frequent handling. Polypropylene (PP) boxes also tolerate autoclaving and offer higher chemical resistance than PC. Choice depends on reuse frequency and sterilization needs.
Well Count and Vial Size
81-well (9&times;9) boxes fit standard 1.8&ndash;2.0 mL cryogenic vials up to ~13 mm outer diameter. 100-well (10&times;10) boxes are used for smaller 1.2&ndash;1.5 mL vials and microcentrifuge tubes up to ~12 mm OD. Always match vial diameter with box well size before ordering.
Box Height: 2-Inch vs. 3-Inch
2-inch boxes are standard for 1&ndash;2 mL cryovials and are most commonly used in biobanking. 3-inch boxes are for larger 3&ndash;5 mL vials and certain centrifuge tubes where extra depth is required.
LN2 Phase Compatibility
Both cardboard and hard-wall boxes can be used in vapor-phase LN2. Only polycarbonate or polypropylene boxes should be used for liquid-phase LN2 because cardboard can break down when submerged.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Cryo boxes are typically rated from &minus;196&deg;C to +121&deg;C depending on material. Cardboard is suitable for vapor-phase LN2 only, while hard-wall plastic boxes can handle more demanding workflows. Proper selection depends on vial size, storage temperature, and how frequently samples are accessed.

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.

</ul>
&nbsp;
<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.

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. 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;

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. Certification includes DNase-free, RNase-free, human DNA-free, and PCR inhibitor-free per independent lot testing.

Capillary Tubes

<h2 dir="ltr">What are Capillary Tubes? </h2>
 Capillary tubes for laboratory use are thin-walled, open-ended tubes&mdash;typically 75 mm long with an internal diameter of 1.1&ndash;1.2 mm&mdash;that collect microvolume blood samples (40&ndash;80 &micro;L) by capillary action from finger-stick or heel-stick punctures, directly from anticoagulated blood collection tubes, or from blood gas analyzers. They are the primary consumables for the micro-hematocrit (packed cell volume, PCV) determination: tubes are filled, sealed, centrifuged at 10,000&ndash;14,500 RPM for 5 minutes, and the ratio of packed red cells to total blood column is read against a hematocrit chart. Globe Scientific manufactures both soda lime glass and plastic (unbreakable) micro-hematocrit capillary tubes, as well as pre-calibrated borosilicate glass tubes for blood gas applications. Choose heparinized capillary tubes for direct finger-stick collection from untreated blood; choose plain (untreated) tubes when filling from an anticoagulated blood collection tube.

</ul>
<h2 dir="ltr"> How to Choose Capillary Tubes</h2>
 Plain vs. Heparinized Plain capillary tubes (blue tip, Globe Scientific) are used when filling from a pre-anticoagulated specimen (EDTA or citrate blood collection tube). Heparinized tubes prevent clotting in samples collected directly from a skin puncture: ammonium heparin&ndash;coated tubes (green tip) and sodium heparin&ndash;coated tubes (red tip) are both available. The tip color is the universal identifier &mdash; confirm the coding convention with your supplier before ordering, as some manufacturers reverse the color assignments. Glass vs. Plastic Soda lime glass capillary tubes (Globe Scientific catalog 51602&ndash;51607) provide excellent capillary action, low surface adsorption, and superior optical clarity for reading the hematocrit column. Plastic capillary tubes (catalog 51620) eliminate the sharps hazard from glass breakage during centrifugation&mdash;a significant occupational safety consideration for high-volume clinical labs processing hundreds of hematocrit determinations daily. Both formats fit standard 75 mm hematocrit centrifuges. Pre-Calibrated (Blood Gas) Tubes Pre-calibrated borosilicate glass capillary tubes (Globe Scientific catalog 51628, I.D. 0.55 mm &plusmn; 0.03 mm) are precision-ground for blood gas and co-oximetry analyzers requiring specific internal volume tolerance. These differ from standard hematocrit tubes in inner diameter; using the wrong tube in a blood gas analyzer causes instrument error codes and inaccurate analyte results. Centrifuge Compatibility All 75 mm micro-hematocrit capillary tubes are compatible with standard hematocrit centrifuges rated for 10,000&ndash;14,500 RPM. Confirm your centrifuge head accepts the tube O.D. (1.5 mm &plusmn; 0.05 mm for Globe Scientific glass tubes) before ordering in bulk.
<h2 dir="ltr"> Specifications Context</h2>
 Globe Scientific soda lime glass micro-hematocrit capillary tubes have an I.D. of 1.15 mm &plusmn; 0.05 mm, O.D. of 1.5 mm &plusmn; 0.05 mm, and a length of 75 mm &plusmn; 1 mm, with a fill volume of approximately 75 &micro;L. The standard centrifugation protocol is 10,000&ndash;14,500 RPM for 5 minutes in a dedicated hematocrit centrifuge. Normal hematocrit ranges: 38&ndash;50% for adult males, 35&ndash;47% for adult females; values outside this range, combined with elevated ESR and other CBC parameters, are used to evaluate anemia, polycythemia, and inflammatory conditions. As of 2026, Globe Scientific is an ISO 9001:2015&ndash;certified manufacturer and MBP-stocked supplier of both glass and plastic capillary tube formats.
