Utilizing Integra's proprietary GripTip™ snap-on connection mechanics, these 300 µL tips eliminate typical friction-fit errors by locking firmly onto the pipette shaft to prevent shifting, loosening, or accidental drop-offs. Designed with an expanded Wide-Bore orifice tip geometry, this consumable dramatically reduces fluid shear forces, ensuring high sample viability during delicate cellular manipulation loops. The tips are supplied pre-sterilized and arranged in standard 96-well configurations across a case of 5 reinforced XYZ racks of 96 tips each (480 total tips).\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnlarged Wide-Bore Orifice Exit: Engineered with a significantly wider internal diameter at the dispensing tip orifice compared to standard 300 µL tips. This geometry reduces the velocity and pressure drop of liquids during aspiration, dramatically lowering mechanical shear stress on fragile cell lines and genomic macromolecules.\u003c\/li\u003e\n\u003cli\u003eProprietary 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 and leak-proof seals without forceful jamming.\u003c\/li\u003e\n\u003cli\u003eHigh-Viscosity Fluid Flow Paths: The wider aperture lowers flow resistance, making it easier to aspirate and dispense heavy, viscous liquids like glycerol, pure resins, oils, and concentrated protein mixtures without lagging or air gap contamination.\u003c\/li\u003e\n\u003cli\u003eHeavy-Duty Carbon-Reinforced XYZ Racks: Racked within specialized, extra-rigid XYZ structural bases.
