Integra 6505 Pipette Tip 12.5 ul GripTip Sterile Low Retention 5 Racks with 384 Tips Each - Total of 1920 Tips

Integra Biosciences® GripTip™ 12.5 µL Low-Retention Sterile Filtered Pipette Tips, XYZ Racks (6505) – Case of 1,920 Tips

The Integra Biosciences® 6505 is a high-performance liquid handling consumable engineered for high-density multichannel pipetting, manual micro-volume transfers, and automated workstation operations. Featuring Integra’s proprietary GripTip™ snap-on connection design, these ultra-low-volume 12.5 µL tips eliminate typical friction-fit inconsistencies by mechanically locking onto the pipette shaft to prevent shifting, loosening, or accidental drop-offs. Combined with a premium **Low-Retention surface modification** and an integrated aerosol barrier filter, these tips are supplied pre-sterilized and arranged in high-density 384-well configurations across a case of 5 reinforced XYZ racks of 384 tips each (1,920 total tips) to ensure absolute aseptic delivery during fine liquid protocols.

Technical Performance & Design

• Proprietary GripTip™ Interlocking Collar: Engineered with a custom molded shoulder ring that snaps tightly over matching multi-channel shaft lobes. This ensures every tip across the array is seated at an identical vertical height, eliminating uneven pick-ups and establishing a leak-proof seal without excessive force.
• Ultra-Hydrophobic Low-Retention Modification: The interior polypropylene surface is chemically altered to minimize surface energy. This repels low-surface-tension fluids, detergents, master mixes, and viscous enzymes, ensuring maximum sample recovery and high microliter reproducibility.
• High-Efficiency Aerosol Protection Filter: Outfitted with a premium porous polyethylene (PE) filter matrix that intercepts aerosolized drops, vapors, and liquid carryover, shielding internal pipette cylinders from bio-contamination and corrosive carryover.
• Heavy-Duty Carbon-Reinforced XYZ Racks: Racked inside a specialized, extra-rigid XYZ structural base configuration. This extra structural reinforcement absorbs the cumulative downward pressure of high-density multi-channel or automated pipetting heads without flexing or shifting.

Key Benefits & Applications

• Next-Generation Sequencing (NGS) Setup: Essential for dispensing ultra-low-volume primer pools, index adapters, and library master mixes, where minor droplet retention skewing alters relative concentration metrics.
• Quantitative PCR Master Mix Loading: Provides clean fluid detachment and aerosol defense when running qPCR or digital PCR runs, protecting delicate reaction loops from false-positive background amplification.
• Automated Plate Array Staging: The structural stability of the heavy-duty XYZ rack matches exact mechanical axes of high-throughput liquid handlers like the Integra ASSIST PLUS, preventing alignment faults during automated tip loading.
• High-Density Proteomic Transfers: Optimizes handling of protein arrays and detergent-heavy assay fluids (containing Triton X-100 or Tween-20) by reducing surface binding friction within the barrel tip.
