AseptiPrime KS-γ capsule filters use mdi PES membrane in gamma compatible polypropylene housing. No adhesives or glue are used in the manufacturing process and all bonding is done by heat welding.The products are deeply validated for use in biopharmaceutical applications.

AseptiPrime KS-γ are manufactured in class 10,000 clean rooms and ISO 9001 certified facilities. Packaging is done in double polybags for direct irradiation by gamma or for convenience of taking AseptiPrime KS-γ in clean areas for making disposable assemblies for subsequent sterilization.
