China High-performance SIP/CIP Capsule Filter Manufacturer

MS factory manufactures SIP/CIP Capsule Filter products specifically designed for pharmaceutical and biotech manufacturing processes that require sterilization in place (SIP) and cleaning in place (CIP) capabilities. In modern pharmaceutical and biotech production, equipment must be sterilized and cleaned in place without disassembly to maintain sterility, reduce contamination risk, and maximize production efficiency. Our capsule filters use a robust plastic housing that maintains high strength and integrity under harsh sterilization conditions, with multiple membrane options including PTFE, PES, and Nylon to match specific application requirements for sterile air and liquid filtration.

Every SIP/CIP Capsule Filter from MS factory is purpose designed for steaming in place sterilization, with a standard filter sealed in a robust plastic housing that remains high strength and integral at harsh application conditions. The filters are available in multiple membrane choices and ratings to accommodate different process requirements, with sanitary flange connections that support easy integration into pharmaceutical and biotech process equipment. The on line connection to automatic integrity testers supports routine integrity verification without disassembly, which is essential for batch release documentation and regulatory compliance in pharmaceutical manufacturing. With cost effective operation, easy connection, and reliable performance under repeated SIP and CIP cycles, our capsule filters provide a dependable filtration solution for sterile pharmaceutical and biotech manufacturing.

Understanding SIP and CIP in Pharmaceutical Manufacturing

Sterilization in place (SIP). 

Involves circulating steam through equipment at elevated temperature and pressure for a defined period to achieve sterility, typically at 121 degree C or higher. Eliminates the need for equipment disassembly and reassembly between batches, reducing labor costs, minimizing contamination risk, and increasing production throughput.

Cleaning in place (CIP). 

Involves circulating cleaning solutions through equipment to remove product residue and contaminants between batches, without disassembly.

Filtration equipment requirements. 

Must be specifically designed to withstand harsh conditions of repeated sterilization and cleaning cycles, including elevated temperatures, pressure cycling, and exposure to cleaning chemicals.

Robust housing design. 

The SIP capable capsule filter uses a robust plastic housing that maintains high strength and integrity under repeated steaming in place cycles, with reliable sealing that maintains integrity under SIP conditions.

Product Configuration and Membrane Selection

These capsule filters are available with multiple membrane options to match specific application requirements for sterile air and liquid filtration in pharmaceutical and biotech manufacturing.

Product Configuration

• PTFE membrane 

SIP capsule filters are ideal for gas and venting applications where hydrophobic behavior and broad chemical compatibility are required, commonly used for sterile air filtration, tank venting, and fermentation air feed.

• PES membrane 

SIP capsule filters are preferred for liquid filtration applications where low protein binding and high flow rates are important, commonly used for sterile filtration of cell culture media, parenteral solutions, and biological products.

• Nylon membrane 

SIP capsule filters provide naturally hydrophilic behavior with strong flow characteristics in aqueous services, suitable for general liquid filtration applications where chemical compatibility and consistent performance are required.

Membrane Selection

Pore size selection depends on specific application requirements, with 0.2 micron being the standard rating for sterile filtration applications that require validated microbial retention. Housing sizes include 5 inch (159 mm) and 2.5 inch (84 mm) nominal dimensions to match different flow rate and footprint requirements. Connection styles include sanitary flange connections that support easy integration into pharmaceutical and biotech process equipment with reliable sealing and cleanability.

Key Design Features for SIP and CIP Applications

Robust plastic housing. 

Maintains high strength and integrity under harsh application conditions including repeated steaming in place cycles, elevated temperatures, and pressure cycling.

Reliable sealing. 

Standard filter sealed in housing using reliable sealing methods that maintain integrity under SIP conditions, preventing bypass and ensuring consistent filtration performance.

Sanitary flange connections. 

Support easy connection with process equipment, providing reliable sealing and cleanability that meets pharmaceutical and biotech hygiene requirements.

On line integrity tester connection. 

Supports routine integrity verification without filter disassembly, allowing operators to verify filter integrity before and after use for batch release documentation and regulatory compliance.

Cost effective operation. 

Compared to stainless steel filter housings, reduces capital and operating costs while maintaining performance and reliability required for sterile manufacturing.

Multiple membrane choices. 

PTFE, PES, and Nylon options with various pore size ratings provide flexibility to match specific application requirements.

Applications

SIP/CIP capsule filters are used across sterile filtration of air and liquid in pharmaceutical and biological product manufacturing, sterile air filtration for fermenters and bioreactors, tank and vessel venting in sterile manufacturing areas, sterile filtration of cell culture media and buffers, sterile filtration of parenteral solutions and biological products, and process gas filtration in aseptic manufacturing environments. In each application, the filter provides reliable sterile filtration with the ability to be sterilized and cleaned in place without disassembly, which is essential for maintaining sterility, reducing contamination risk, and maximizing production efficiency.

Beyond sterile filtration, these capsule filters are also used in applications that require repeated sterilization and cleaning cycles between batches, such as multi product manufacturing facilities where equipment must be thoroughly cleaned and sterilized between product campaigns. The robust housing and reliable sealing support repeated SIP and CIP cycles without loss of performance or integrity. Whether you need a sterile air filter for a fermenter that requires daily SIP cycles or a sterile liquid filter for a parenteral filling line that requires CIP between batches, MS factory can provide a reliable and cost effective SIP/CIP capsule filter solution with factory direct pricing and technical support.
