About us
Kefilbao Filter Technology (Suzhou) Co., Ltd. is a high-tech company specializing in bag filters and folding filter elements, integrating product research and development, production, and sales.

SPSTCS sterilizing Grade Filter Polyethersulfone Cartridges are 100% integrity tested, it is constructed of double-layer hydrophilic asymmetric polyethersulfone membrane. It offers broad chemical compatibility, high flow rates at low pressure drops, and low extractables.
Polyethersulfone is particularly suited for the filtration of products that contain substances that adsorb to the media, The lower binding characteristics of polyethersulfone make it a good choice for filtration of valuable protein solutions such as vaccines and biologicals.
