The capsule integrates a hydrophobic PTFE membrane with a high temperature resistant housing, enabling filtration in systems where in-line steam sterilization is required.\n\u003c\/p\u003e\n\n\u003ch3\u003eTechnical overview\u003c\/h3\u003e\n\u003cp\u003e\nSIP-capable capsule filters allow sterile gas filtration without the need for stainless steel filter housings and cartridge assemblies. The filter capsule can be sterilized directly within the process system using steam-in-place procedures.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThe robust housing construction supports repeated steam sterilization cycles while maintaining mechanical stability and filtration integrity. These filters are commonly used for sterile air supply and tank vent filtration in biopharmaceutical processes. :contentReference[oaicite:1]{index=1}\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eOperating principle\u003c\/h2\u003e\n\n\u003cp\u003e\nDuring operation, the gas stream enters the capsule through the inlet connection and passes through the hydrophobic PTFE membrane.
