China Suppliers Factory Challenge Filair® PTFE Hydrophobic Sterile Filters for High Retention & Throughput

The Challenge IM Capsule Filters are expertly designed for the biopharmaceutical industry, covering five essential series: clarification, pre-filtration & sterilizing-grade, sterile, mycoplasma removal, and gas filtration. With particle retention capabilities ranging from 0.1 to 30 μm, these filters meet comprehensive requirements from cell culture clarification to final product sterilization. Our filters are robust, supporting high-temperature steam sterilization and gamma irradiation, making them compatible with a wide variety of common biopharmaceutical solvents, Manufactured in China, our filters consist of molded parts and sealing components that are free from colorants and comply with Class VI and ISO 10993 biocompatibility standards. This minimizes leachables and extractables, ensuring hygienic processing for all applications. Each filter undergoes stringent dual integrity testing during production, with two independent test methods required for release, ensuring a 100% factory pass rate, Additionally, our filters adhere to ISO 9001 quality management and GMP standards, having successfully passed USP endotoxin, USP / biocompatibility, and USP extractables tests, with no animal-derived TSE/BSE risk. All products are validated by multiple internationally recognized agencies, such as SGS and NF, offering biopharmaceutical suppliers fully verified and reliable filtration solutions for every stage of the process. Trust in Challenge IM Capsule Filters for top-quality manufacturing from a leading China supplier dedicated to your biopharmaceutical filtration needs
