Challenge Pore® PES Low-Protein-Binding Sterile Filters from China - Reliable Suppliers & Factory Quality

,

The Challenge IM Capsule Filters are designed by leading China suppliers to meet the stringent requirements of the biopharmaceutical industry. Our filters cover five essential series: clarification, pre-filtration & sterilizing-grade, sterile, mycoplasma removal, and gas filtration, ensuring particle retention from 0.1 to 30 μm. This comprehensive range supports every stage of the biopharmaceutical process, from cell culture clarification to final product sterilization.

,

Manufactured in our state-of-the-art factory, these filters are capable of withstanding high-temperature steam sterilization and gamma irradiation, making them compatible with a wide array of commonly used biopharmaceutical solvents. All molded parts and sealing components are free from colorants and adhere to Class VI and ISO 10993 biocompatibility standards, thereby minimizing leachables and extractables for hygienic processing.

,

To guarantee quality, each filter undergoes dual integrity testing during manufacturing, employing two independent test methods to achieve a 100% factory pass rate. Our filters comply with ISO 9001 quality management and GMP standards. Additionally, they have successfully passed USP endotoxin, USP / biocompatibility, and USP extractables tests, with no risk of animal-derived TSE/BSE.

,

All products are validated by multiple internationally recognized agencies, including SGS and NF, offering fully verified and reliable filtration solutions tailored for the biopharmaceutical process. Trust Challenge IM Capsule Filters, your reliable choice from China suppliers, for unmatched quality and performance.
