Sterile filter membrane (aqueous)

This sterile filter membrane from Tianjin Jinteng is developed for aqueous-based filtration in laboratory and microbial analysis applications. Manufactured in a class 100,000 cleanroom and available with Nylon 6 or mixed cellulose ester (MCE) media, it offers pore sizes of 0.2 µm and 0.45 µm in 47 mm or 50 mm diameters. Each membrane is individually packaged and sterilized using ethylene oxide, minimizing the risk of re-contamination after sterilization. The grid-patterned variants are particularly suited for microbial detection and colony counting, while the uniform pore structure ensures reliable particle retention and consistent flow. These characteristics make it a practical choice for routine filtration, sterility testing, and microbiological analysis in research and quality control settings.
