Hamilton CO-RE II Pipette Tip 1000 ul Filter Conductive 40 Racks Total 3840 Tips

Hamilton 1000 µL Filtered Conductive CO-RE II Automated Pipette Tips, Racked (235905) – Case of 40 Racks (3,840 Tips)

The Hamilton 1000 µL Filtered Conductive CO-RE II Pipette Tips (235905) are high-precision automated liquid handling consumables designed exclusively for Hamilton Microlab STAR, VANTAGE, and NIMBUS liquid handling platforms equipped with 1000 µL CO-RE liquid channels or 96-Multi-Probe Heads. Engineered with Hamilton’s proprietary Compressed O-Ring Expansion (CO-RE II) technology, these tips feature a re-engineered tip crown that establishes an airtight, lock-and-key seal with low loading and ejection forces, significantly reducing mechanical stress on the liquid handling arms and extending system service intervals. Molded from high-grade conductive polypropylene impregnated with carbon black, these tips enable real-time Capacitive Liquid Level Sensing (cLLs) for high-accuracy tracking of liquid interfaces, even when aspirating low-volume or foaming samples. Supplied as a full case of 40 racks containing 96 tips each (3,840 tips total), this product provides maximum throughput, liquid handling fidelity, and contamination protection for high-volume automated workflows.

Technical Performance & Key Attributes

• CO-RE II Sealing Technology: Precision-molded tip crown interfaces seamlessly with Hamilton O-ring channels, delivering consistent coaxial alignment, zero tip tilting, and reduced tip attachment/ejection wear.
• Conductive Polypropylene Matrix: Carbon-impregnated resin permits high-sensitivity capacitive liquid level detection (cLLS), allowing pipetting channels to submerge to minimal depths and minimize exterior tip immersion contamination.
• Integrated Aerosol Filter Barrier: Premium hydrophobic polyethylene filter blocks liquid splash-over and aerosol transport, protecting high-density liquid handling heads from internal channel contamination.
• High Volumetric Precision & Accuracy: Extended tip geometry ensures precise aspirating and dispensing kinetics across the entire 10 µL to 1000 µL operating range.
• Automation-Grade Rack Housing: Rigid, heavy-duty 96-position racks are engineered to withstand automated robotic gripping and high axial tip pickup forces without frame flexing.
