Challenge Pore® PES High-Flow Hydrophilic Filters - China Suppliers for Biopharmaceutical Factory Solutions

The Challenge IM Capsule Filters are a comprehensive solution for biopharmaceutical processes, featuring 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 address all steps from cell culture clarification to final product sterilization. Our filters are engineered to withstand high-temperature steam sterilization and gamma irradiation, and they are compatible with a wide array of commonly used biopharmaceutical solvents, Manufactured in our state-of-the-art factory in China, all molded parts and sealing components are devoid of colorants, complying with Class VI and ISO 10993 biocompatibility standards. This ensures minimal leachables and extractables for hygienic processing. Each filter undergoes rigorous dual integrity testing during production, utilizing two independent methods for release, ensuring a 100% factory pass rate, Our filters adhere to ISO 9001 quality management and GMP standards, having successfully passed USP endotoxin, USP / biocompatibility, and USP extractables tests, with no risk of animal-derived TSE/BSE. As reliable suppliers in the biopharmaceutical industry, we assure that all products are validated by multiple globally recognized agencies, including SGS and NF, delivering fully verified filtration solutions for all stages of biopharmaceutical processes
