低吸附移液器吸头

Rainin低吸附枪头可用于粘性液体和低表面张力液体

A low retention pipette tip works well with viscous and low-surface-tension liquids. Viscous (e.g., glycerol) and low-surface-tension liquids (e.g., isopropyl alcohol) adhere to the inside of standard pipette tips, increasing experimental uncertainty. The unique Rainin molding process creates tips with a highly repellent coating – a “superhydrophobic” surface over the entire tip. This prevents any adhesion between samples and the polypropylene tip surface, facilitating enhanced fluid movement.

Low Retention Tips: New PFAS-Free Option

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.

Advantages of Low Retention Pipette Tips

Advanced Repellent Surface

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.

Ideal for Difficult Liquids

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.

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 the retained sample after dispensing, Rainin LR Tips eliminate a major source of pipetting inaccuracy.

FinePoint Tips for Pipetting Accuracy

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.

Not All Low Retention Tips are Created Equal

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.
