Single-layer Cartridge Filter (PES 0.2μm)
Product Introduction
Alioth Alipore® DHF Single-layer Cartridge Filter is a 0.2μm single-layer polyethersulfone (PES) filter that can efficiently retain bacteria (LRV > 6) and particulate contaminants. It has wide chemical compatibility and low leaching level, thus suitable for the bioburden control and pre-filtration of various fluids. It can provide more effective protection at different stages of bioprocess, prolonging the service life of sterilizing filters and safeguarding other processing systems. This filter is produced in a controlled environment, and its manufacturing process conforms to ISO9001 quality system standards. Each cartridge filter undergoes an integrity testing during the process of manufacturing.
