Integra Pipette Tip 12.5 ul Extended Length Sterile Filtered 5 Racks with 384 Tips Each

Integra Biosciences GripTip 12.5 µL Extended Length Filtered Pipette Tips – 44 mm Extra Long Reach, XYZ Rack Format, Pre-Sterilized, Hydrophobic Filter, Low-Force Positive Snap-On Seal (MPN: 6405)

The Integra Biosciences 6405 GripTip system is a high-precision, automation-ready liquid handling consumable engineered explicitly to eliminate tip loosening, misalignment, and aerosol contamination during low-volume micro-pipetting workflows. Injection-molded from medical-grade virgin polypropylene, these 12.5 µL Extended Length (44 mm) tips feature an elongated geometry designed to reach deep into 1.5 mL microcentrifuge tubes, 96/384-well deep plates, and narrow storage vessels without bringing the pipettor shaft into contact with tube walls. Built with Integra’s patented GripTip snap-on shoulder mechanism, these tips lock securely onto the pipette fitting rim with minimal loading force, guaranteeing that every tip sits at an identical, perfectly level height for flawless touch-offs. Outfitted with a high-efficiency 100% pure hydrophobic filter, these pre-sterilized tips block radioactive, corrosive, or infectious aerosol carryover from penetrating the internal shaft of handheld or automated liquid handling systems.

Technical Performance and Structural Design

• Patented GripTip Snap-On Locking Rim: Designed with an engineered internal shoulder that snaps firmly over the multi-channel fitting rim. This mechanism prevents tips from loosening, dripping, or falling off, ensuring precise, unvarying tip height across 384-well plates.

• 44 mm Extended Length Geometry: The lengthened slender profile allows effortless access to the bottom of 1.5 mL tubes, deep-well microplates, and tall narrow blocks without scraping the pipette nose cone against vessel walls, preventing cross-contamination.

• Integrated Hydrophobic Aerosol Filter: Features a high-density, inert polyethylene filter barrier. The filter stops liquid overfill and aerosolized vapors from passing into the pipette shaft, protecting both the instrument internals and downstream samples from cross-contamination.

• High-Rigidity XYZ Rack Format: Supplied in reinforced, high-density XYZ racks designed to withstand the physical forces of automated multi-channel loading without flexing or bowing during automated or manual tip pickup cycles.
