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.
