A static, single use assembly. It is used in the pharmaceutical industry and contains plastic tubing, caps, retainers, stoppers, couplers, bags and filters in one package. The filters are made from polypropylene and are designed for the filtration of air (no liquid is transferred through these filters). Liquids/fluids move through the assembly which displace the air, the displaced air then passes through the filters. The filters are used to maintain a sterile environment within the assemblies by filtering particles and micro-organisms from the liquid/fluid. The micron measurement of the filters is typically 0.2µm. All parts are imported together with the filter being the essential character of the whole assembly.
