0.45μm 47mm PES Filter Membrane Discs Non-Sterile For Microbiological Analysis

An air stop filter membrane is a highly hydrophilic PES disc membrane used in infusion therapy. It is typically placed at the bottom of a drip chamber. The instant wetting ability of an air stop filter membrane activates the membrane as an intusion flux filter once it contacts fluids. This means that when the membrane comes into contact with a fluid, it immediately starts to work as a filter, preventing fine particles or air from entering the patient's bloodstream. Pore size of our air stop filter membrane ranges from 0.1um to 5um, which effectively retains particles larger than related pore size and prevent the entry of air into the patient's bloodstream, most importantly, when the drip container runs out of drug solutions, the surface tension of liquid within the porous structure of wet membrane automatically stops the flow, and forms a fluid protection surface to protect the downstream infusion line from air entry. This ensures that the infusion therapy is safe and effective and helps to reduce the risk of complications such as air embolism, which can be life-threatening. Air stop filter membranes are commonly used in hospitals and other healthcare applications.

The auto air stop filter membranes offered by XINNA are non-sterile, but they can be autoclaved and gamma sterilized to meet specific requirements. As a manufacturer of membrane filters, we can customize the pore size and diameters to suit your needs and provide tailor-made samples for approval in a very short period of time.
