Description of Water Sterilization Prefiltration
WECHENFIB PES-Syringe Sterilization Filter have good hydrophilicity, low protein adsorption, high chemical and thermal stability, strong acid and alkali resistance (pH 1-13) solution stability, high mechanical strength and low dissolution rate. It can be sterilized by autoclaving (30min/121℃) and ethylene oxide, etc. It is suitable for water-based solution filtration and biological sample preparation.
