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.

 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;
