Frequently Asked Questions
What are the primary applications of the Challenge Pore® PES capsule filter?
Typical applications include the prefiltration of cell culture media, filtration of intermediates and bulk products, filtration of serum and blood products, and sterile filtration of final biological products.
What sterilization methods can be used with this capsule filter?
The filter is fully compatible with sterilization by high-temperature steam (at 121 °C for 30 minutes, for up to 5 cycles) or by gamma irradiation within the range of 25–40 kGy.
What materials are used in the construction of the filter?
The filter membrane is made of Hydrophilic Polyethersulfone (PES). The inner/outer cages and capsule housing are constructed from Polypropylene (PP), and the capsule vent O-ring is made from Silicone Rubber.
Does the filter meet international biosafety standards?
Yes. The filter is compliant with USP <87> Non-cytotoxic standards and meets the USP <88> Class VI plastic biocompatibility requirements. It also maintains endotoxin levels below 0.25 EU/mL.
What are the maximum operating pressure and temperature limits?
The maximum operating temperature is 80℃. The maximum differential pressure limit is 0.55 MPa at 25℃ and decreases to 0.1 MPa at 80℃.
What is the filtration accuracy of the membrane?
The filtration accuracy of the dual-layer Hydrophilic Polyethersulfone (PES) membrane is rated at 0.2 + 0.1 μm.
