Featuring the proprietary GripTip system, these tips provide a flawless, secure seal that will never loosen, leak, or fall off during critical high-volume liquid handling procedures. This specific 4445 catalog number is pre-sterilized and features a built-in hydrophobic aerosol filter, providing a highly effective barrier against cross-contamination. Molded from 100% virgin polypropylene in a highly controlled cleanroom environment, they carry the VIAPURE certification, guaranteeing absolute sample purity for sensitive genomic, transcriptomic, and tissue culture workflows.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eProprietary GripTip Snap-On Design:\u003c\/b\u003e The specialized rim securely locks over the multi-lobe pipette fitting, completely eliminating the risk of tips physically detaching or leaking fluid over expensive microplates or deep-well blocks.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePositive Stop Shoulder:\u003c\/b\u003e Features an engineered internal shoulder that acts as a physical stop.
