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;

<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 LTS-Compatible Pipette Tips?</h2>
 LTS (LiteTouch System) pipette tips use a cylindrical collar that mates with the cylindrical shaft of Rainin LTS pipettes, as opposed to the conical taper used on standard universal-fit tips. The cylindrical-to-cylindrical interface reduces the insertion force needed to seat the tip, lowering the repetitive-strain load on the hand and wrist during high-throughput pipetting &mdash; the primary ergonomic benefit Rainin's LiteTouch design addresses.&nbsp; LTS tips are required for Rainin LTS pipettes &mdash; no other tip format seats correctly. Third-party LTS-compatible tips offer equivalent performance at a lower cost than OEM.

<h2 dir="ltr"> How to Choose LTS-Compatible Tips</h2>
 Confirm Your Pipette Has LTS Not all Rainin pipettes use LTS. Rainin Classic (original PIPET-LITE) and older Rainin models use standard conical shafts and require universal-fit tips. LTS is found on Rainin Pipet-Lite XLS+, Pipet-Lite M, and multichannel L8 and L12 LTS models. Look for 'LTS' in the model name on the pipette barrel before ordering LTS-specific tips. Filtered vs Non-Filtered Non-filtered LTS tips are appropriate for buffer, media, and reagent dispensing. Filtered LTS tips &mdash; with an aerosol-barrier element &mdash; are required for PCR, RNA, and contamination-sensitive work. See the dedicated [LTS Compatible Filter Tips](mbpinc.net/consumables/liquid-handling-products/filtered-pipette-tips/lts-compatible-filter-tips [confirmed]) page for filtered LTS options. Volume Range LTS tips span approximately 20 &micro;L through 5,000 &micro;L across single-channel and multichannel pipette ranges. Common volumes: 20 &micro;L (LTS SL L10/L20), 200 &micro;L (LTS SL L200, L300), 1,000 &micro;L (LTS SL L1000), and 5,000 &micro;L macro tips for large-volume LTS pipettors. OEM Rainin vs Third-Party Compatible Rainin OEM LTS tips are manufactured to the tightest dimensional specification for LTS instruments. Third-party LTS-compatible tips are precision-moulded to LTS cylindrical geometry and certified DNase/RNase-free; they provide equivalent performance in routine applications and are typically 20&ndash;40% lower in cost than Rainin OEM tips. For critical applications (clinical diagnostics, cGMP workflows), confirm compatibility with your quality system before switching from OEM. Packaging LTS tips are available in hinged racks (10 racks &times; 96 tips = 960 tips/box) and refill wafer inserts for compatible rack bases. Sterile and non-sterile options are available across the range. 
<h2 dir="ltr"> Specifications Context</h2>
 LTS-compatible tips are manufactured from virgin polypropylene; some formats use hydrophobic low-retention PP for reduced liquid adhesion. LTS-compatible tips use hydrophobic resin technology for low retention and are certified RNase/DNase/DNA/PCR inhibitor-free. LTS tips are available from multiple third-party suppliers at 20&ndash;40% lower cost than Rainin OEM, with equivalent documented performance.&nbsp;

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;

Single Channel Pipettors

<h2 dir="ltr">What Are Single-Channel Pipettors?</h2>
 A single-channel pipettor is the single most widely used liquid handling instrument in molecular biology, cell biology, and clinical research. It transfers precise volumes between 0.1 &micro;L and 5,000 &micro;L, one well or tube at a time, using an air-displacement piston mechanism. The piston creates a partial vacuum that aspirates liquid into a disposable tip; advancing the piston fully dispenses the liquid. A spring-loaded tip ejector releases the used tip without hand contact for contamination control. Manual models depend on finger force and offer simple, battery-free operation; electronic models add programmable aspiration/dispensing speeds, multi-dispense modes, and up to 5 custom pipetting programs.&nbsp; A set of four manual single-channel pipettors (P10, P20, P200, P1000) covers 95% of molecular biology liquid handling; add electronic models for high-throughput repetitive work.

<h2 dir="ltr"> How to Choose a Single-Channel Pipettor</h2>
 Volume Range: Build a Complete Bench Set A standard four-pipettor bench set covers P10 (1&ndash;10 &micro;L), P20 (2&ndash;20 &micro;L), P200 (20&ndash;200 &micro;L), and P1000 (100&ndash;1,000 &micro;L). For sub-microliter work (sequencing, single-cell), add a P2 (0.2&ndash;2 &micro;L). For large-volume dispensing (media prep, column loading), add a P5000 (1,000&ndash;5,000 &micro;L). Avoid selecting a volume range that places your target dispense below 20% of the maximum &mdash; accuracy degrades at the low end of any range. Manual vs Electronic Manual single-channel pipettors (Eppendorf Research Plus, Gilson PIPETMAN Classic, Rainin Pipet-Lite XLS+) are the standard for routine lab work: field-calibratable, autoclavable, and requiring no power source. Electronic single-channel pipettors (Eppendorf Research Pro, Rainin Pipet-Lite XLS+ Electronic) add: programmable aspiration/dispense speed (5 speeds), multi-dispense (repeat pipetting) mode, mix mode, dilution mode, and backlight LCD volume display. Electronic models reduce hand fatigue in workflows exceeding 200&ndash;300 tip changes per day. Tip Compatibility Three tip systems cover the market: standard conical (universal fit &mdash; fits Eppendorf Research Plus, Gilson PIPETMAN, Rainin non-LTS, Thermo, Sartorius/BioHit); Rainin LTS cylindrical (requires LTS-specific tips &mdash; lower force insertion); Eppendorf epT.I.P.S. proprietary (tightest fit for Eppendorf instruments). Select the tip system that matches your pipettor purchase and existing tip inventory before committing to a brand. Autoclavability and Chemical Resistance Manual pipettors from Eppendorf, Gilson, and Rainin have fully autoclavable lower sections (121&deg;C, 15 psi, 15 min). Electronic pipettors have autoclavable nose cones only &mdash; the electronic module cannot be autoclaved. Calibration and Service All single-channel pipettors are factory-calibrated per ISO 8655. Field recalibration tools are available for Eppendorf, Gilson, and Rainin to perform in-lab gravimetric verification without external service. 
<h2 dir="ltr"> Specifications Context </h2>
 ISO 8655 Part 2 accuracy spec for a 200 &micro;L air-displacement pipettor: &plusmn;0.8 &micro;L systematic error, &le;0.3 &micro;L random error (Eppendorf Research Plus specification at 200 &micro;L). Most manual pipettors weigh 70&ndash;120 g; electronic models weigh 150&ndash;220 g. Operating temperature range: typically 15&ndash;40&deg;C. Eppendorf Research Plus, Gilson PIPETMAN Classic, and Rainin Pipet-Lite XLS+ LTS remain the three dominant single-channel pipettor platforms in North American research labs.&nbsp;

Vacuum Filtration

<h2 dir="ltr">What are Vacuum Bottle-Top Filter Systems?</h2>
 Vacuum bottle-top filter systems are single-use, sterile filtration assemblies consisting of a graduated polystyrene funnel with an integrated membrane filter bonded to a polystyrene receiver bottle, connected by a hose-port adaptor to a house vacuum line or benchtop vacuum pump. The applied negative pressure (&minus;50 to &minus;100 kPa) draws liquid through the membrane into the receiver bottle, which is sealed after filtration for immediate use or cold-room storage.&nbsp;

<h2 dir="ltr"> How to Choose Vacuum Filtration Systems</h2>
 PES vs. PVDF Membrane for Vacuum Filtration PES membranes provide low protein binding (~1&ndash;2 &micro;g/cm&sup2;), high flow rates, and broad aqueous-solution compatibility &mdash; the standard for routine DMEM, RPMI, HBSS, PBS, and supplement-containing media sterilization. PVDF membranes have slightly lower protein binding than PES and greater chemical resistance to mild organic solvents, mild acids, and alkaline solutions. Use PVDF when filtering protein-rich solutions (FBS, antibody preparations, conditioned medium with high protein content) or when mild organic solvents are present in the filter solution. Volume Selection 250 mL systems (50 mm diameter membrane, 50 mL funnel) suit small media aliquots, supplement solutions, and transfection reagent preparations. 500 mL systems (90 mm diameter membrane, 150 mL funnel) are the routine lab workhorse for standard 500 mL media bottle preparation and FBS filtration. 1,000 mL systems (90 mm diameter membrane, 350 mL funnel) handle full-liter media preparations and large-volume buffer sterilization. All NEST systems include a pre-attached, graduated polystyrene receiver bottle in the corresponding volume. Pore Size: 0.10 &micro;m vs. 0.22 &micro;m vs. 0.45 &micro;m 0.22 &micro;m is the sterilizing grade per USP &lt;1229.2&gt; and ICH Q9: retains all bacteria and fungi; used for routine cell culture media, PBS, and buffer preparation. 0.45 &micro;m is the clarification grade: used as a pre-filtration step before 0.22 &micro;m to remove large particulates from turbid or high-biomass samples (FBS, conditioned media, cell culture supernatants, crude lysates), extending 0.22 &micro;m filter throughput by 3&ndash;5&times; on difficult samples. 0.10 &micro;m is the mycoplasma-removal grade: required when preparing media for Mycoplasma-sensitive primary cell culture or when processing serum or supplementary reagents that may harbor Mycoplasma species. Note that 0.10 &micro;m filtration is substantially slower than 0.22 &micro;m due to the tighter membrane pore structure. Practical Tips for Maximum Throughput Pre-wet the membrane by briefly passing 5&ndash;10 mL of sterile water through before the sample &mdash; this wets the hydrophilic PES or PVDF membrane and reduces initial resistance. For FBS and other viscous solutions, pre-filter through 0.45 &micro;m before the 0.22 &micro;m step. Maintain a vacuum at &minus;50 to &minus;80 kPa; excessive vacuum (&gt; &minus;100 kPa) can shear fragile membrane pores and increase non-specific protein adsorption. Do not autoclave the assembled bottle-top filter &mdash; PES and PS components are not rated for autoclave sterilization.

Syringe Filters

<h2 dir="ltr">What are Syringe Filters?</h2>
 Syringe filters are self-contained, disposable filtration units comprising a polypropylene (PP) housing enclosing a flat-sheet membrane, with a female Luer lock inlet and a male Luer lock outlet. They are attached to a standard syringe, the sample is drawn up, and pushed through the membrane by manual plunger pressure. Standard disc diameters are 4 mm, 13 mm, 25 mm, and 33 mm; membrane pore sizes are 0.22 &micro;m (sterilizing grade) and 0.45 &micro;m (clarification grade), with 0.10 &micro;m available for mycoplasma removal. Effective filtration areas: 13 mm filter &asymp; 0.92 cm&sup2;; 25 mm filter &asymp; 2.98 cm&sup2;. Globe Scientific syringe filters, a confirmed MBP brand, are available in PP housing with PES, PVDF, CA (cellulose acetate), MCE, and nylon membranes in 13 mm and 30 mm diameters, sterile (individually wrapped) and non-sterile (bulk), 0.22 &micro;m and 0.45 &micro;m. Choose syringe filters for volumes of 1&ndash;150 mL; choose vacuum bottle-top filters for volumes above 150 mL.

<h2 dir="ltr"> How to Choose Syringe Filters</h2>
 Diameter Selection by Sample Volume 13 mm syringe filters (effective area 0.92 cm&sup2;) handle up to 10&ndash;15 mL per filter before flow resistance becomes impractical. Use with 1&ndash;10 mL syringes. 25 mm syringe filters (2.98 cm&sup2;) handle 10&ndash;100 mL per filter. Use with 10&ndash;60 mL syringes. 33 mm syringe filters (approximately 5&ndash;6 cm&sup2;) handle up to 150 mL and are the largest practical syringe filter format. For volumes above 150 mL, switch to a vacuum bottle-top filter system. Matching filter diameter to sample volume prevents premature membrane clogging and excessive plunger force. Membrane Chemistry for Syringe Filters PES (Polyethersulfone): Low protein binding, high flow rate, aqueous compatibility. Standard choice for biological sample sterilization, cell culture supplement filtration (antibiotics, glutamine, growth factors), and conditioned medium aliquots. Not suitable for strong organic solvents or concentrated acids. PVDF (Polyvinylidene fluoride, hydrophilic): Low protein binding &mdash; among the lowest of all syringe filter membranes, with protein recovery rates &gt;90&ndash;99.9% documented for antibody and enzyme solutions. Compatible with mild organic solvents, weak acids, and most aqueous solutions. The first choice when filtering precious protein solutions (antibodies, enzymes, viral preparations) is where maximum protein recovery is critical. Not suitable for pure DMSO (use PTFE). Nylon (Polyamide): Low extractables, broad chemical compatibility including mixed aqueous-organic solvents, methanol, acetonitrile, and DMSO-water mixtures. Standard for HPLC mobile phase filtration and dissolution testing. Higher protein binding than PES or PVDF &mdash; avoid for biological samples where protein loss is a concern. MCE (Mixed Cellulose Ester): Low cost, aqueous applications only; moderate protein binding. Suitable for general buffer preparation, water sterilization, and non-critical sample preparation. Not compatible with organic solvents or strong acids. CA (Cellulose Acetate): Low protein binding, similar to PES. Suited for biological sample filtration and sterility testing applications. Contains surfactant treatment for wettability &mdash; check for extractable compatibility in downstream assays. PTFE (Polytetrafluoroethylene, hydrophilic): Maximum chemical resistance &mdash; compatible with pure DMSO, concentrated acids and bases, and aggressive organic solvents. The only membrane choice for 100% organic solvent filtration. For aqueous solutions, use hydrophilic PTFE (pre-wetted with methanol or IPA before aqueous filtration unless the hydrophilic version is selected). Sterile vs. Non-Sterile Syringe Filters Sterile syringe filters (individually gamma-irradiated or E-beam sterilized, individually packaged) are required for cell culture media sterilization, supplement preparation, and sample preparation for biological culture. Non-sterile bulk-packed filters (Globe Scientific non-sterile formats) are appropriate for HPLC mobile phase preparation, analytical sample clarification, and non-biological applications where sterility of the filtrate is not required.
