Integra Biosciences 4425 Pipette Tip 125 ul Sterile Filtered 4 Racks with 384 Tips Each

Integra Biosciences 125 µL Sterile Filter GRIPTIPS 384-Tip High-Density Rack (4425) – 4 Racks (1536 Tips)

The Integra Biosciences 125 µL Sterile Filter GRIPTIPS (4425) are high-precision liquid handling consumables specifically designed for use with Integra 384-channel handheld electronic pipettes (such as VIAFLO 384 and MINI 96) as well as 16-channel and 24-channel multichannel pipettes. Manufactured from high-grade virgin polypropylene, these low-retention tips feature an integrated hydrophobic polyolefin filter barrier that prevents aerosol transfer and liquid back-flow from contaminating the pipette internal mechanisms or cross-contaminating samples. Engineered with Integra's proprietary GRIPTIP snap-on connection system, these tips snap securely onto pipette fittings with minimal loading force, guaranteeing that tips will never loosen, leak, or fall off during high-density multi-dispensing routines. Each racks contains 384 sterile tips (1536 tips total), this product delivers certified aseptic, high-throughput performance for microplate assays and molecular workflows.

Technical Performance & Key Attributes

• Positive Snap-On Lock (GRIPTIP System): Features a shoulder design that snaps over the fitting rim of Integra pipettes, providing a tactile lock that ensures uniform tip height and prevents tips from dropping or leaking.
• Hydrophobic Filter Barrier: Integrated hydrophobic pore filter blocks aerosols and liquid over-aspiration, protecting pipette shafts from biological, chemical, or radioisotope contamination.
• High-Density 384-Tip Rack Configuration: Precision-molded 384-position matrix maintains perfect tip alignment for seamless multichannel liquid dispensing into 384-well and 96-well microplates.
• Low Retention Surface Properties: Premium polypropylene formulation prevents liquid clinging and surface binding, optimizing sample recovery for enzymes, viscous liquids, and low-concentration buffers.
