Integra Biosciences Pipette Tips 1250 ul Griptip 20 Racks

Integra 4443 GripTip Pipette Tips – 1250 µL, Non-Sterile, Racked

The Integra 4443 is a highly specialized 1250 µL (1.25 mL) pipette tip engineered exclusively for use with Integra's advanced line of handheld manual and electronic pipettes. 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.

Technical Performance and Design

• Proprietary GripTip Snap-On Design: 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.

• Positive Stop Shoulder: Features an engineered internal shoulder that acts as a physical stop. This ensures every tip across an 8-, 12-, or 16-channel pipette is loaded at the exact same height and perfectly aligned for ultimate precision.

• Low Attachment and Ejection Forces: The GripTip geometry completely bypasses the need to "hammer" the pipette into the tip box, drastically reducing repetitive strain injury (RSI) risks during prolonged high-volume pipetting sessions.

• High-Purity Polypropylene: Molded from 100% virgin polypropylene, the smooth internal surfaces minimize unspecific fluid binding, ensuring maximum sample recovery of biological buffers and viscous reagents.
