Integra Biosciences Pipette Tip 1250 ul Griptip VIAFLO Sterile Filter 20 Racks

Integra Biosciences® GripTip™ 1250 µL Sterile Filtered Pipette Tips, XYZ Racked (6445) – Pack of 1920 Tips

The Integra Biosciences® 6445 is a high-capacity, heavy-duty liquid handling consumable engineered to deliver exceptional volumetric accuracy for multi-channel handheld pipettes and automated benchtop liquid handling workstations. Utilizing Integra’s proprietary GripTip™ snap-on connection mechanics, these 1250 µL tips physically lock onto the pipette shaft to prevent wobbling, loosening, or accidental drop-offs during intensive fluid sweeps. Outfitted with an integrated hydrophobic aerosol barrier filter, these large-volume tips are supplied pre-sterilized and arranged as a premium package of 20 reinforced racks containing 96 tips each (1920 total tips) to ensure completely contamination-free molecular biology and cell culture staging operations.

Technical Performance & Design

• Proprietary GripTip™ Interlocking Collar: Features a precision-molded internal shoulder ring that snaps tightly over matching multi-channel shaft lobes. This mechanical connection ensures all tips sit at exactly the same vertical height across a multi-channel head, providing perfect alignment, uncompromised touch-offs, and leak-proof seals.
• High-Efficiency Aerosol Protection Filter: Outfitted with an integrated hydrophobic filter barrier matrix. This block prevents airborne vapors, liquids, and aerosols from traveling up into the internal pipette barrel, protecting your equipment from corrosive sample carryover and preventing sample-to-sample cross-contamination.
• XYZ Reinforced Automation Racks: Packed in specialized, ultra-rigid XYZ polymer racks engineered to withstand heavy vertical tip-loading pressures. The heavy-duty housing prevents rack deflection or flexing during robotic tip pickups, ensuring perfect multi-channel coupling.
• Strict Cleanroom Quality Control: Every lot is gamma-irradiated and strictly verified to comply with high purity baselines, ensuring the tips are completely free of detectable RNase, DNase, human DNA, endotoxins, and pyrogens.

Key Benefits & Applications

• High-Throughput Workstation Automation: Essential for loading multi-channel pipetting blocks on automated liquid handling systems like the VIAFLO 96, guaranteeing perfect structural alignment across dense multi-well arrays.
• Deep-Well Microplate Aliquoting: Extended tip profile allows clean access into 2.0 mL deep-well storage plates, block arrays, and 15 mL conical tubes without bringing the non-sterile pipette shaft into contact with the container walls.
• Cell Culture and Media Preparation: Sterile, certified purity baselines ensure that delicate mammalian cell lines, transfection reagents, and dense growth mediums remain unadulterated by ambient laboratory bio-burden.
• Accurate Master Mix Scaling: Permits rapid, safe scaling of larger master mixes and buffer reagents, providing reliable volumetric transfer with minimal fluid hang-up or droplet formation.
