Rainin STACKED 1000UL LQR LOWRET PSTRL 768/8

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.

Sterilised by gamma irradiation — a method that completely inactivates the biological activity of micro-organisms without leaving chemical residues.

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).
