Utilizing Integra’s proprietary GripTip™ snap-on locking design, these large-volume 1250 µL tips eliminate typical friction-fit seating errors, ensuring they lock tightly onto the pipette shaft and never loosen, leak, or drop off mid-protocol. Outfitted with an ultra-smooth **Low-Retention surface modification** and an integrated high-density aerosol barrier, these tips are supplied pre-sterilized and arranged in 96-well configurations across a case of 5 reinforced XYZ racks of 96 tips each (480 total tips) to maintain absolute aseptic sample isolation.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProprietary GripTip™ Interlocking Collar: Features a precision-molded internal shoulder that snaps tightly over matching multi-channel shaft lobes. This mechanical connection ensures all tips sit at exactly the same vertical height across a multi-channel head, providing perfect alignment and leak-proof seals without forceful jamming.\u003c\/li\u003e\n\u003cli\u003eUltra-Hydrophobic Low-Retention Polymer: The internal polypropylene structure utilizes specialized resin technology to lower surface energy. This prevents viscous or low-surface-tension fluids (like master mixes, glycerol, and detergent-rich buffers) from binding or wetting the inner tip walls, guaranteeing high sample recovery.\u003c\/li\u003e\n\u003cli\u003eHigh-Efficiency Aerosol Protection Filter: Outfitted with an integrated hydrophobic polyethylene (PE) filter barrier. This matrix blocks airborne vapors, liquids, and aerosols from traveling up into the internal pipette barrel, protecting your equipment from corrosive sample carryover and preventing sample-to-sample cross-contamination.\u003c\/li\u003e\n\u003cli\u003eHeavy-Duty Carbon-Reinforced XYZ Racks: Racked within specialized, extra-rigid XYZ structural bases.
