An Introduction to Self-Sealing Filters

2017-12-08 08:49:00

Sintered polyethylene filters are widely used in medical practice. Filtration involves what is being filtered, either air or liquid. In oxygen concentrators, for example, air filters make oxygen clean and fresh, suppress noise. Liquid filters, such as dissolution filters, remove particulates from the feed stream.

What if we only need air filtration, but prevent aqueous liquid from passing through the filter? For instance, in surgical waste management, waste liquid must be introduced into containers, sealed, waiting for properly treated. Disposable suction liners equipped with such filters are used in nowadays hospitals.

These filters are often called shut-off valves. At Biocomma, they are part of the portfolio of our H 2OStop® self-sealing filters.
