Serological Pipettes

<h2 dir="ltr"> What Are Serological Pipettes?</h2>
 Serological pipettes are calibrated, graduated, sterile polystyrene disposable pipettes used with a motorised pipette controller to transfer measured volumes of liquid in the 1&ndash;100 mL range. They are the primary tool for cell culture media transfer, buffer preparation, reagent dispensing in volumes above 1 mL, and serial dilutions requiring volumetric accuracy in the millilitre range. They differ from aspirating pipettes &mdash; which have no graduations and are used only for vacuum-assisted waste removal &mdash; and from microcentrifuge tubes, which are not dispensing instruments. Serological pipettes are the correct format for any measured liquid transfer &ge;1 mL in cell culture or reagent preparation; pair them with a motorised pipette controller for safe, ergonomic operation.

<h2>How to Choose Serological Pipettes</h2>
 Volume: Standard Sizes and ISO 7550 Colour Coding ISO 7550 assigns a specific colour code to each serological pipette volume: 1 mL = red; 2 mL = yellow; 5 mL = blue; 10 mL = orange; 25 mL = green; 50 mL = purple (pink/violet depending on supplier). Colour coding allows quick visual volume identification when multiple sizes are in use simultaneously in a BSC. Packaging: Individual Wrap vs Bulk Individually wrapped sterile pipettes are required for cell culture, molecular biology, and aseptic technique. Plastic/plastic peel-open packaging eliminates paper particulate from paper/plastic wrappers &mdash; important in sensitive cell culture applications and for RNA work. Bulk-packed (canister or bag) formats are cost-effective for non-sterile applications such as buffer preparation and reagent dispensing in fume hoods. Construction: 1-Piece vs 3-Piece 1 mL, 2 mL, and 5 mL serological pipettes are typically one-piece moulded polystyrene constructions. 10 mL, 25 mL, and 50 mL pipettes use 3-piece ultrasonically welded construction (Globe Scientific) for the body-to-cone and body-to-cap joints &mdash; essential for the structural integrity of larger formats under aspiration vacuum. Tip and Graduation Features Negative graduations (markings above the nominal maximum) allow volumes slightly above nominal to be read. Fine-point tips with slow drip-off improve pipetting accuracy during cell culture media transfers. Some brands offer Wobble-not-style pipettes with reduced barrel flex for easier single-hand operation. Filter Plug Material Cotton filter plugs are standard; synthetic plugs (polyethylene or polypropylene) are preferred when processing organic solvents or any media that might wick through a cotton plug.

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.

Pipette Tips

<h2 dir="ltr">What Are Pipette Tips?</h2>
 Pipette tips are disposable polypropylene cones that attach to the shaft of an air-displacement pipette, forming the liquid-contact surface for aspiration and dispensing. The seal between the tip collar and the pipette shaft is the single most important factor in volumetric accuracy; a poorly fitting tip introduces systematic volume error that causes the instrument to deviate from its calibrated specification. Tips span micro volumes (0.1&ndash;10 &micro;L) through standard (20&ndash;200 &micro;L and 100&ndash;1,000 &micro;L) to high-volume (up to 1,250 &micro;L), with variants for filtered aerosol protection, low-retention liquid release, extended reach into deep vessels, and wide-bore dispensing of viscous samples.&nbsp;

</ul>
&nbsp;
<h2 dir="ltr">How to Choose Pipette Tips</h2>
 Collar Size and Pipette Compatibility Tip collar diameter determines fit: 3.8 mm collar for &le;10 &micro;L pipettes; 6.1 mm collar for &le;200 &micro;L; approximately 7.5&ndash;8.0 mm collar for P1000 pipettes. Universal fit tips use these standard collar sizes and are compatible with Eppendorf Research, Rainin Classic (non-LTS), Thermo Finnpipette, and Sartorius/BioHit. Rainin LTS and Eppendorf epT.I.P.S. use proprietary collar geometry and require instrument-specific tips. Filtered vs Non-Filtered Aerosol-barrier filter tips contain a hydrophobic PE or cellulose plug that blocks aerosol and liquid from reaching the pipette barrel; required for PCR, qPCR, and RT-PCR setup, RNA extraction, and work with biohazardous samples. Non-filter standard tips are appropriate for buffer, media, and reagent dispensing where cross-contamination through the barrel is not a concern. Low-Retention vs Standard Polypropylene Low-retention tips are injection-moulded from hydrophobic polypropylene with reduced surface energy or coated to minimise liquid adhesion on the inner wall. They improve accuracy at &le;10 &micro;L and for dispensing viscous, protein-containing, or organic solvent samples. Standard PP tips leave small residual volumes in the tip after dispensing; this residue is negligible at 200 &micro;L but significant at 2&ndash;5 &micro;L. Extended-Length and Wide-Bore Extended-length tips (also called long tips or gel-loading tips) reach into deep 15 mL and 50 mL tubes, cryovials, and electrophoresis gel wells. Wide-bore tips have an enlarged aperture for dispensing viscous samples, cell suspensions, and tissue lysates without shearing. Packaging Format Hinged 96-tip racks are standard for manual pipetting. Reload inserts fit into reusable rack bases to reduce per-tip cost and plastic waste. Bulk bags provide the lowest cost per tip for non-sterile applications.
&nbsp;
<h2 dir="ltr">Specifications Context</h2>
 Pipette tips are certified DNase-free, RNase-free, ATP-free, human DNA-free, PCR inhibitor-free, and pyrogen-free per independent lot testing. Virgin polypropylene free of additives, antistatic agents, and dyes is the standard material. ISO 8655 compliance for the pipette system depends on tip-pipette seal quality; confirm tip compatibility with your specific pipette model.&nbsp; Sorenson Bioscience universal and filtered tips, Globe Scientific, and Nest Scientific lines are stocked by MBP Inc.&nbsp;

<h2 dir="ltr"> What Are Universal Fit Pipette Tips?</h2>
 Universal fit pipette tips use collar diameters standardised across most major air-displacement pipette brands, allowing a single tip product to seat on pipettes from multiple manufacturers. The three primary collar sizes are: 3.8 mm for &le;10 &micro;L tips, 6.1 mm for &le;200 &micro;L tips, and approximately 7.5&ndash;8.0 mm for P1000 tips. These collar sizes cover Eppendorf Research Plus, Rainin Classic (non-LTS), Thermo Finnpipette, Sartorius/BioHit, and VWR pipettes. Universal fit tips cover most lab pipettes at a lower cost per tip &mdash; the exception is Rainin LTS, which needs dedicated LTS tips.

 Volume Range: Match Tip to Pipette 10 &micro;L universal tips (3.8 mm collar) cover 0.1&ndash;10 &micro;L single-channel pipettes and the P10 range. 200 &micro;L universal tips (6.1 mm collar) cover P20, P50, P100, and P200 pipettes. 1,000 &micro;L universal tips cover P1000 pipettes and are available in standard-length and extended-length formats. 1,250 &micro;L macro universal tips accommodate high-volume dispensing steps in the 1,000&ndash;1,250 &micro;L range. Standard vs Filtered Universal Tips Standard universal tips are sufficient for buffer, media, and reagent dispensing. Filtered universal tips &mdash; with hydrophobic PE or cellulose aerosol barrier &mdash; are required for PCR setup, RNA work, and any contamination-sensitive application. Using filtered tips universally reduces contamination risk in shared pipettes at the cost of approximately 1.5&ndash;2&times; the price of standard tips. Low-Retention Universal Tips Low-retention universal tips minimise residual volume on the inner tip wall. This matters at &le;10 &micro;L, where standard tips may retain 0.2&ndash;0.5 &micro;L, creating a systematic under-delivery error. Sorenson's universal low-retention tips maintain compatibility with all major standard-collar pipettes. Packaging Format Racked (hinged 96-tip rack): standard for manual pipetting. Reload inserts: drop into reusable rack bases; 20&ndash;30% lower per-tip cost and reduced plastic. Bulk (non-sterile bag): lowest cost per tip for non-sterile buffer/media work. Sterile racked tips are required for cell culture, RNA, and clean applications. OneTouch / Ergonomic Formats OneTouch reload formats allow the full tip insert to be loaded into the pipette simultaneously, reducing repetitive-strain impact from individual tip-loading in high-throughput workflows. 
<h2 dir="ltr"> Specifications Context</h2>
 Universal fit tips are manufactured from 100% virgin polypropylene, certified DNase-free, RNase-free, ATP-free, human DNA-free, pyrogen-free, and PCR inhibitor-free per lot. Sorenson Bioscience universal tips are manufactured in a Class 100,000 cleanroom, pre-sterilised, and sold through MBP Inc. in standard racks, EcoRack reloads, and bulk formats. Universal fit tips remain the highest-volume tip category in North American research labs due to multi-brand compatibility and lower cost per tip versus pipette-specific variants.&nbsp; 
If you&rsquo;re setting up a workflow or mixing pipette brands in the same lab, it&rsquo;s usually worth sorting tip compatibility early &mdash; it removes a lot of small daily friction that adds up over time. <a href="https://mbpinc.net/contact-us">Contact the MBP team</a> to get a tailored quote!

Universal Fit Pipette Tips

<h2 dir="ltr">What Are Bulk &amp; Racked Pipette Tips?</h2>
 Racked pipette tips are pre-loaded into a 96-position hinged polypropylene rack (8 rows &times; 12 columns), matched to standard single-channel and 8-channel multichannel pipette workflows. Bulk tips are supplied as loose tips in resealable bags of 500&ndash;1,000 or more, intended for self-loading into existing rack frames or bulk-bag dispensers. For labs that discard full racks after each use, bulk bags offer a significant reduction in per-tip cost; for labs requiring sterile, pre-organised tips, hinged racks are the standard. Choose racked tips for sterile/organised workflows; choose bulk bags when sterility is not required and cost per tip is the primary driver.

<h2 dir="ltr"> How to Choose Between Bulk and Racked Formats </h2>
 Sterility Requirements Racked tips are available pre-sterilised (EO or gamma) and are individually certified DNase-free, RNase-free, ATP-free, human DNA-free, and PCR inhibitor-free per lot &mdash; required for cell culture, PCR setup, RNA work, and any sterility-sensitive application. Bulk bag tips are typically non-sterile; they can be autoclaved by the user at 121&deg;C (15 psi, 15 min) before use if sterility is needed, though autoclaving adds handling time. Throughput and Format Racked 96-tip formats support 8-channel multichannel pipetting with aligned well positions. Bulk bags are efficient for single-channel repetitive dispensing where tips are picked individually. For high-throughput multichannel workflows, the Refill Station (reload insert) format combines the alignment benefits of a rack with the lower cost of bulk supply. Volume Range 10 &micro;L tips: for P2, P10 single-channel pipettes, microvolume dispensing, sequencing gel loading. 200 &micro;L tips: the highest-volume format in most research labs &mdash; P20, P100, P200 range. 1,000 &micro;L / 1,250 &micro;L tips: for P1000 pipettes; available in standard and extended-length formats for deep-tube access. Standard-length tips suit standard Eppendorf and Falcon tubes; extended-length tips reach 15 mL and 50 mL conical tube bottoms. Autoclavable Racks Polypropylene hinged racks withstand repeated autoclave cycles at 121&deg;C without dimensional distortion. Confirm the rack material is PP (not polystyrene) before autoclaving &mdash; PS racks deform under steam sterilisation. Pack Sizes and Case Economics Standard racked packs: 96 tips/rack &times; 10 racks/box &times; 10 boxes/case = 9,600 tips/case for 200 &micro;L format. Bulk bags: 500 or 1,000 tips/bag; cases of 10 bags = 5,000&ndash;10,000 tips at significantly lower cost per tip. 
<h2 dir="ltr"> Specifications Context</h2>

Funnels

<h2>What Are Laboratory Weighing Funnels?</h2>
&nbsp;
Laboratory weighing funnels are single-use antistatic polypropylene (PP) funnels specifically designed for the weighing-and-transfer step in analytical chemistry, pharmaceutical weighing, and sample preparation workflows. Unlike standard powder funnels, weighing funnels have one flat side that allows the funnel to rest stable on a balance pan during mass measurement, and a conical stem sized to the neck of a specific volumetric flask volume. After the sample mass is recorded, the funnel inserts directly into the flask neck, and the sample is transferred by tipping or rinsing&mdash;providing quantitative, loss-free transfer into narrow-neck vessels. Available in extra small (fits microtubes and 5&ndash;20 mL flasks) through extra-extra-large (fits 1000 mL+ vessels). Antistatic weighing funnels are single-use; washing removes the antistatic treatment. Reusable funnels needing autoclave sterilization should be standard polypropylene powder funnels, not antistatic weighing funnels.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>Powder funnels with wide stems for smooth solid transfer</li>
<li>Long-stem funnels for controlled pouring into narrow containers</li>
<li>Short-stem funnels for faster liquid transfer</li>
<li>Filter funnels for use with standard filter paper</li>
<li>Chemical-resistant plastic funnels for lab compatibility</li>
<li>Disposable funnels for single-use workflows</li>
</ul>
&nbsp;
<h2>How to Choose Laboratory Weighing Funnels</h2>
&nbsp;
Match Size to Flask Neck
The critical specification for a weighing funnel is the stem outer diameter relative to the flask neck inner diameter. Extra small fits 96-well microtubes and 5&ndash;20 mL volumetric flasks; small fits 20&ndash;50 mL; medium fits 50&ndash;200 mL; large fits 200&ndash;500 mL; extra large fits 500&ndash;1000 mL. A funnel that is too wide will not insert and will spill during transfer&mdash;when in doubt, choose one size smaller.
Disposable Antistatic vs. Reusable PP
For analytical weighing of fine powders, use disposable antistatic PP funnels&mdash;the antistatic surface dissipates charge that causes powder adhesion. For bulk transfer of coarse materials or liquids where static is not an issue, standard reusable polypropylene powder funnels (autoclavable at 121&deg;C, large-bore stem) are more economical and can be sterilized between uses.
Assorted vs. Individual Packs
Assorted packs covering extra small through extra large provide flexibility when flask sizes vary across experiments and reduce the number of individual SKUs to manage. Individual packs are more economical when only one funnel size is used at high volume.
Flat-Side Stability
All antistatic weighing funnels have one flat side on the funnel body. This flat face allows the funnel to rest stably on a balance pan without rolling during the weighing step before transfer&mdash;a design feature absent on standard laboratory funnels.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Antistatic polypropylene weighing funnels achieve antistatic performance through a surface additive incorporated during molding; this is a surface treatment rather than a bulk polymer property. The flat side is designed to rest on a balance pan while keeping the stem vertical for direct transfer into volumetric flasks. As of 2026, these funnels are standard in pharmaceutical QC and analytical chemistry labs for gravimetric transfer workflows compliant with USP procedures.

Biohazard Bags

<h2 dir="ltr">What are Biohazard Bags?</h2>
 Biohazard bags are polyethylene pouches printed with the universal biohazard symbol and standardized warning text, used to contain, transport, and dispose of biological specimens and infectious waste in clinical, diagnostic, and research laboratory settings. They are manufactured in two functionally distinct categories: specimen transport bags (thin-walled LDPE, zipper-closure, with document pouch) for routing patient specimens from collection point to laboratory; and autoclave/waste bags (heavy-gauge polypropylene, heat-sealable) for containing infectious solid waste before steam sterilization at 121&ndash;136 &deg;C. Choose a specimen transport bag for courier or inter-department specimen routing; choose an autoclave bag for infectious solid waste destined for steam sterilization.

<h2 dir="ltr"> How to Choose Biohazard Bags</h2>
 Specimen Transport vs. Waste/Autoclave Function Specimen transport bags (Globe Scientific catalog 4923&ndash;4950) are LDPE, zipper-locked, with a separate document pouch for the requisition form and a tear zone for rapid opening at the receiving lab. They are not rated for autoclaving. Autoclave bags (PP, 0.05 mm, 12&times;26 in. or 24&times;32 in.) withstand 121&ndash;136 &deg;C sterilization cycles and comply with OSHA 29 CFR 1910.1030 markings for biohazardous waste disposal. Size Selection for Specimen Transport Globe Scientific offers 6&times;9 in. (for blood tubes, urine cups, small specimens), 8&times;10 in. (for multiple tubes or swab collections), and 12&times;15 in. (for large containers, pathology specimens). The 6&times;9 in. bag with absorbent pad (catalog 4924) is the most common format for clinical specimen routing; the pad absorbs up to 10 mL of liquid in the event of tube breakage. Absorbent Pad Requirement IATA Dangerous Goods Regulations and the UN3373 Biological Substance Category B shipping requirements mandate an absorbent material sufficient to absorb the total liquid volume of the primary container. The 6&times;9 in. with absorbent pad format meets this requirement for standard tube shipments. Confirm pad absorbency against your primary container volume before use in P650 mailing kits. STAT vs. Standard Globe Scientific STAT bags (catalog 4950) are red-tinted 6&times;9 in. bags with a document pouch and tear zone &mdash; the red color alerts laboratory staff to prioritize the specimen. Use STAT bags for critical or time-sensitive specimens that bypass standard routing. Closure Type Zipper-closure bags allow repeated access and are used where the specimen may need to be resealed for courier transit. Glue-closure (tamper-evident seal) bags prevent re-opening and are preferred for chain-of-custody specimens (forensics, drug testing) and any application where tamper evidence is required.
<h2 dir="ltr"> Specifications Context</h2>
 Globe Scientific specimen transport bags are manufactured from LDPE with a printed biohazard symbol and special handling checkboxes. The 6&times;9 in. standard format (catalog 4923) and STAT format (4950) hold cases of 1,000 bags (100/pack &times; 10 packs). The 8&times;10 in. (4926) and 12&times;15 in. (4929) formats are cases of 1,000 and 500, respectively. Autoclave bags used for infectious solid waste must comply with OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), which requires fluorescent orange or orange-red color-coding or a biohazard symbol on all containers holding regulated waste. Globe Scientific biohazard bags are manufactured under ISO 9001:2015 quality management standards. Bags are non-sterile; sterile transport systems for specimens requiring sterility assurance should use appropriately certified collection vessels inside the bag.
