Integra Biosciences Pipette Tip 125 ul Inserts Sterile 5 Racks with 384 Tips Each

Integra Biosciences 4426 GripTip Pipette Tips – 125 µL, Green Choice Inserts, Pre-Sterilized

The Integra 4426 is a specialized 125 µL 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 liquid handling procedures. This specific 4426 catalog number is part of Integra’s "Green Choice" initiative, providing environmentally friendly, pre-sterilized tip inserts designed to be loaded directly into reusable empty 384-tip racks. Molded from 100% virgin polypropylene in a highly controlled cleanroom environment, they carry the VIAPURE certification, guaranteeing absolute sample purity and precise volumetric delivery without generating excessive plastic waste.

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.

• 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.

• Green Choice Refill System: The eco-friendly packaging utilizes lightweight plastic inserts that drastically reduce plastic waste by over 60% compared to purchasing standard racked tips, significantly lowering the carbon footprint of your laboratory.

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