We employ a unique molding process to produce tips with a uniform field of highly-repellent fluoropolymer molecules that form an impenetrable “superhydrophobic” surface. The result: liquids and molecules are suspended above the polypropylene tip surface, allowing difficult liquids to glide effortlessly in and out of the tip.
The super-repellent surface of Rainin LR tips "normalizes" the flow characteristics of fluids with diverse compositions and physical characteristics (viscosities, surface tension, density, hydrophobicity, etc.) The result: enhanced pipetting accuracy across a broader range of sample types. Rainin Low Retention Pipette Tips provide greater peace of mind and better data fidelity when pipetting.
