Bio-3 Capsule Filters

The Bio-3 Capsule Filters are developed and researched for sterile filtration process with reliable and stable sterilization performance. It’s designed with external vent valve structure that can remove Gas-liquid easily and efficiently. Its built-in sterile grade hydrophilic polyethersulfone (PES) membrane has the characteristics of high flow rate, high contaminant holding capacity and excellent chemical compati-bility, ensuring its wide range of applications such as bioburden and bacteria removal in the culture medium, intermediate solution, buffers and other upstream and downstream processes. Bio-3 Capsule Filters can help shorten process time, reduce production costs and improve economic benefits.
