PES Liquid Capsule Filter


Delivers superior throughput for broad challenging feed streams while minimize product loss in sterile filtration
- Dual layer and highly asymmetric PES membrane minimize pressure build-up while processing large volume fluids
- Structure design helps minimize dead zone which can cause loss of high value products
- Broad chemical compatibility, pH 1~14, allows use in a range of chemistries including acids and bases
- Product has been rigorously validated to product specification and industry standards with comprehensive documentation to support compliance
- Gamma capability ensures that integrators can connect these filters into any customer-specific, single-use assembly and provide it as a sterile, final assembled product
