Low Retention Tip With Advanced Repellent Surface
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 LR tips provide greater peace of mind and better data fidelity when pipetting.
Significantly Less Residual Volume
The uniform repellent fluoropolymer "field" on the surface of Rainin LR tips prevents any interaction between the sample and the polypropylene tip surface. In this short video, a propylene glycol-based food colorant demonstrates how Rainin LR low retention tips eliminate sheeting activity. By dramatically reducing retained sample after dispensing, Rainin LR Tips eliminates a major source of pipetting inaccuracy.
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. FinePoint tips discharge completely for optimal pipetting accuracy.
