A company provides filter vents made with proprietary Tetratex expanded-PTFE membranes for a variety of medical device applications, such as devices requiring acoustic and protective vents, drainage bags, IV-administration sets, ostomy bags, urine bags, and device packaging. The vents are hydrophobic, toxicity-tested to USP Class VI standards, clean and nonshedding, chemically inert, and thermally stable. They feature high particulate and bacterial removal rates and high rates of airflow, and are designed to minimize extractables. Oleophobic and acoustically transparent materials are optionally available. Equipped with design and filtration-material expertise, the manufacturer offers custom systems that are easily integrated into the customer’s device or application.
