Challenge Pore® PES Low-Protein-Binding Filters from China Suppliers - Sterile Solutions from Factory

The Challenge IM Capsule Filters are essential for biopharmaceutical processes, offering five key series: clarification, pre-filtration & sterilizing-grade, sterile, mycoplasma removal, and gas filtration. With particle retention capabilities from 0.1 to 30 µm, these filters meet the comprehensive requirements for cell culture clarification to final product sterilization. Manufactured in China, our filters support high-temperature steam sterilization and gamma irradiation and are compatible with a wide range of biopharmaceutical solvents, All molded parts and sealing components are free from colorants and comply with Class VI and ISO 10993 biocompatibility standards, effectively minimizing leachables and extractables for hygienic processing. As a trusted supplier, each product undergoes rigorous dual integrity testing during production, utilizing two independent test methods for release, guaranteeing a 100% factory pass rate, Our filters adhere to ISO 9001 quality management and GMP standards and have successfully passed USP endotoxin, USP / biocompatibility, and USP extractables tests, ensuring no animal-derived TSE/BSE risk. Validated by multiple internationally recognized agencies such as SGS and NF, our Challenge IM Capsule Filters provide reliable and fully verified filtration solutions for the entire biopharmaceutical manufacturing process directly from our factory in China

    Frequently Asked Questions

    1. What is the chemical compatibility of the PES capsule filter?

    The Hydrophilic Polyethersulfone (PES) capsule filter offers broad chemical compatibility across a wide pH range of 1 to 14.

    2. What are the maximum operating pressure and temperature limits?

    The filter can operate at a maximum temperature of 80℃. The maximum differential pressure limits are 0.55 MPa at 25℃ and 0.1 MPa at 80℃.

    3. What materials are used to construct the capsule filter?

    The filter membrane is constructed from Hydrophilic Polyethersulfone (PES), the inner/outer cages and capsule housing are made of Polypropylene (PP), and the capsule vent O-ring is made of Silicone Rubber.

    4. Does the filter meet biosafety standards?

    Yes. The filter endotoxin levels are <0.25 EU/mL. It is compliant with USP <87> Non-cytotoxic standards and meets USP <88> Class VI plastic biocompatibility requirements.

    5. How can the PES capsule filter be sterilized?

    The capsule filter can be sterilized using high-temperature steam sterilization (at 121 °C for 30 minutes, up to 5 cycles) or through gamma irradiation within a range of 25–40 kGy.
