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.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProprietary GripTip™ Interlocking Collar: Engineered with a custom molded shoulder ring that snaps tightly over matching multi-channel shaft lobes.
