Integra Biosciences Pipette Tip 1250 ul Griptip Sterile Filtered 20 Racks

Integra 4445 GripTip Pipette Tips – 1250 µL, Filtered, Sterile

The Integra Biosciences 4445 is a specialized 1250 µL (1.25 mL) pipette tip engineered exclusively for use with Integra's advanced line of manual and electronic pipettes. 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.

Technical Performance and Design

• Proprietary GripTip Snap-On Design: 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.

• 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.

• Aerosol Barrier Filter: The highly porous filter completely blocks liquid bypass and prevents volatile aerosols from entering the pipette shaft, protecting both the instrument and subsequent samples from carryover contamination.

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