Rainin RACKS 200UL LQR LOWRET FLTR 960/10

The low-retention coating consists of a uniform hydrophobic layer applied to the inner surface of the tip. Because aqueous liquids have a higher contact angle on this surface, adhesion is minimised and liquid ejection is maximised. This is particularly relevant for expensive or scarce samples (proteins, DNA, RNA) and liquids with low surface tension such as detergents or isopropanol.

The integrated aerosol barrier filter protects the pipette mechanism against aerosol contamination from radioactive, biological or chemical samples. The filter absorbs liquid droplets that can be released during forceful pipetting, preventing cross-contamination between samples and damage to the piston.

All Rainin BioClean Ultra pipette tips are manufactured in a Class 100,000 cleanroom with fully automated material handling (zero human contact). Each batch is tested for: human DNA (<0.32 pg), bacterial DNA (<1 pg), RNase (≤10⁻⁹ KU/µL), DNase (≤10⁻⁷ KU/µL), endotoxins (≤0.001 EU/mL), proteins (<2 ng/tip), proteases (≤500 ng/mL), PCR inhibitors (not detected) and ATP (<2×10⁻¹² mg/µL).
