Achieve accurate results from precious samples with new Hydrophobic Low Retention tips. While many low retention tips use “forever chemical” additives, these tips are PFAS-free like most Genuine Rainin tips. A novel non-leaching additive creates a hydrophobic surface without per- and polyfluoroalkyl substance (PFAS) “forever chemicals. With the same excellent performance and quality as all Genuine Rainin low retention tips, switching is easy.
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 LR tips provide greater peace of mind and better data fidelity when pipetting.
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.
FinePoint tips taper to a fine orifice diameter. Their slender design, in combination with thin, flexible walls, creates an exceptionally supple tip that assists in sample touch-off. The narrow orifice aperture and thin wall surrounding the orifice provides minimal surface area for residual sample to adhere to during sample dispensing.
More common manufacturing methods, such as dipping or tumbling tips in a fluoropolymer bath, can produce tips with incomplete and uneven coatings that can adversely affect pipetting accuracy. In addition, tips made with "diamond polished" molds – often touted as low retention – do nothing to prevent samples from reacting with the polypropylene and binding to the tip surface.
