Integra Biosciences Pipette Tips 125 ul GripTip 10 Racks of 384 Tips

Integra Biosciences 4423 GripTip Pipette Tips – 125 µL, Non-Sterile, 384-Tip Racks

The Integra 4423 is a specialized 125 µL pipette tip engineered exclusively for use with Integra's advanced line of 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 fall off during vigorous liquid transfers or multi-dispense side-well touch-offs. Packaged in sturdy, high-density racks (5 racks of 384 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 a multichannel pipette is loaded at the exact same height and perfectly aligned for ultimate precision.

• 384-Tip High-Density Format: The 384-well rack configuration is specifically designed to interface seamlessly with 16-channel Integra pipettes, allowing for ultra-efficient transfers into 384-well microplates without wasting rack space.

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

Product Specifications

Key Benefits & Applications

• High-Throughput Workflows: The 384-tip format dramatically increases pipetting efficiency for researchers performing intensive serial dilutions, PCR setups, and automated assays into 384-well plates.

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

• Strict Analytical Purity: Manufactured under stringent VIAPURE standards, guaranteeing the tips are safe for sensitive molecular biology assays and genomic extractions without the added cost of pre-sterilization.

• 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 multi-plate processing.
