Unlike standard universal tips that require forceful hammering and rely on friction, the proprietary GripTip system utilizes a unique snap-on mechanism. The rim of the tip securely locks over the multi-lobes of the pipette fitting, guaranteeing that the tips will never leak, loosen, or physically detach, even when dispensing heavy, viscous fluids. Packaged in robust SBS-format racks (5 racks of 96 tips), these non-sterile tips are manufactured under strict cleanroom conditions. They carry the VIAPURE certification, guaranteeing they are completely free of RNase, DNase, endotoxins, and PCR inhibitors right out of the box.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eProprietary GripTip Snap-On Design:\u003c\/b\u003e The specialized rim securely locks over the pipette tip cone, completely eliminating the risk of tips physically detaching or leaking fluid over expensive microplates or deep-well blocks.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePositive Stop Shoulder:\u003c\/b\u003e Features an engineered internal shoulder that acts as a physical stop.
