Sterilizing-Grade PES Filters (0.45 μm / 0.2 μm)
Alioth Alipore® ZHC filters use sterilizing-grade 0.2 µm PES membrane as the final filtration layer and construct with double-layer asymmetric PES membrane, which allow for various combinations of membrane pore sizes to meet the requirements for filtration precision in different applications. The filters are suitable for a variety of sterile filtration of process fluids. Alipore® ZHC filters are validated by strict filtration performance guarantees, with wide chemical compatibility, low protein adsorption, high flow rate and high capacity to optimize process efficiency and cost effectiveness.
