High Mycoplasma Retention Challenge Pore® PES Hydrophilic Filters from China Suppliers and Factory for Biopharmaceuticals

,

Introducing the Challenge IM Capsule Filters, designed to meet the stringent requirements of the biopharmaceutical industry. Our filters encompass 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 advanced filters are ideal for various applications, from cell culture clarification to final product sterilization. Manufactured in our state-of-the-art factory in China, we ensure high-quality standards and compliance with Class VI and ISO 10993 biocompatibility standards. All molded parts and sealing components are devoid of colorants, thereby minimizing leachables and extractables, which guarantees hygienic processing.Each filter undergoes rigorous dual integrity testing during production, with two independent test methods ensuring a 100% factory pass rate. Our products meet ISO 9001 quality management and GMP standards and have successfully passed USP endotoxin, USP / biocompatibility, and USP extractables tests, eliminating any animal-derived TSE/BSE risks. As leading suppliers in the filtration industry, we are validated by multiple internationally recognized agencies, including SGS and NF, providing reliable and fully verified filtration solutions tailored for the biopharmaceutical process.

    Frequently Asked Questions (FAQ)

    Q1: What are the key advantages of the Challenge Pore® PES capsule filter's membrane material?
    The filter uses Hydrophilic Polyethersulfone (PES) for the membrane, which offers broad chemical compatibility (pH 1-14), high particle retention reliability, and extremely low extractables.
    Q2: What is the filtration accuracy of this capsule filter?
    The filter features a unique dual-layer design with a filtration accuracy rating of 0.2+0.1μm, ensuring reliable retention of bacteria and fine particulates.
    Q3: How can the PES capsule filter be sterilized?
    It can be safely sterilized using high-temperature steam (at 121 °C for 30 minutes, up to 5 cycles) or through gamma irradiation within a range of 25–40 kGy.
    Q4: Does the filter meet international biosafety standards?
    Yes. The filter has endotoxin levels of <0.25 EU/mL, is fully compliant with USP <87> Non-cytotoxic testing, and meets USP <88> Class VI plastic biocompatibility guidelines.
    Q5: What are the maximum operating limits for pressure and temperature?
    The maximum allowable operating temperature is 80℃. The maximum differential pressure limits are 0.55MPa at 25℃ and 0.1MPa at 80℃.
    Q6: What materials are used to construct the housing and cage parts?
    The inner cage, outer cage, and capsule housing are all constructed from durable Polypropylene (PP), while the capsule vent O-ring is made of high-quality Silicone Rubber.
