Integra Biosciences Pipette Tips 300 ul Griptip Non-Sterile 30 Racks

Integra Biosciences 4433 GripTip Pipette Tips – 300 µL, Non-Sterile, Racked

The Integra 4433 is a highly specialized 300 µL pipette tip engineered exclusively to interface with Integra’s advanced line of multichannel and automated 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 fall off during vigorous liquid transfers or multi-dispense side-well touch-offs. Packaged in sturdy, SBS-footprint racks (5 racks of 96 tips), these non-sterile tips are manufactured under strict cleanroom conditions. Although non-sterile, 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.

• 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 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 reagents.

Key Benefits & Applications

• High-Throughput Workflows: The industry standard for automated microplate filling, serial dilutions, and multi-channel pipetting where a single loose tip can ruin an entire analytical assay.

• Exclusive Integra Compatibility: Engineered precisely to maximize the performance of Integra's VOYAGER adjustable tip-spacing pipettes and the ASSIST PLUS automated robotic platforms.

• Strict Analytical Purity: The VIAPURE manufacturing standard guarantees the tips are safe for sensitive molecular biology assays, genomic extractions, and PCR preparations without the added cost of pre-sterilization.

• Autoclavable Racks: The robust standard racks can withstand standard steam autoclaving (121°C) if a researcher requires sterile tips for downstream tissue culture applications.
