Integra 6433 Pipette Tips 300 ul Viaflo Filtered 20 Racks with 96 Tips Each

Integra Biosciences® GripTip™ 300 µL Sterile Filtered Pipette Tips, Green Choice Inserts (6433) – Case of 1,920 Tips

The Integra Biosciences® 6433 is a high-performance liquid handling consumable engineered to deliver extreme volumetric precision for automated multi-channel pipetting heads and handheld electronic pipetting platforms. Featuring Integra’s proprietary GripTip™ snap-on connection mechanics, these 300 µL tips eliminate typical friction-fit seating errors by mechanically locking onto the pipette shaft to prevent shifting, loosening, or accidental drop-offs. Outfitted with an integrated high-efficiency aerosol barrier filter, these tips are supplied pre-sterilized and arranged as a bulk facility package of 20 Green Choice inserts/racks containing 96 tips each (1,920 total tips) to support high-throughput, contamination-free molecular biology workflows.

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.
• Sustainable Green Choice Refill System: Engineered as an eco-conscious, low-waste packaging configuration. These inserts reload pre-arranged, contamination-free tip blocks directly into reusable standard boxes, reducing environmental plastic packaging waste and storage footprint.
• 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.
• Precision Quantitative PCR Assays: Sterile, certified purity baselines ensure that delicate master mixes, expensive enzyme primers, and target cDNA fragments remain completely unadulterated by ambient laboratory bio-burden.
• Sustainable Footprint Refills: Designed to be paired with reusable, heavy-duty Integra tip boxes. Technicians can rapidly click the Green Choice inserts into position with one hand, minimizing the laboratory recycling volume.
• Aseptic Tissue Culture Isolation: Pre-sterilized, cleanroom-packaged design makes it perfect for delicate cellular manipulation, medium dosing, and reagent aliquoting inside sterile Class II biosafety environments.
