Bottle-top filters are used in research laboratories for sterilization or laboratory fluid clarification. The attachments are ideal for use with cell culture and serum-containing media, and asymmetrical hydrophilic membrane styles provide high flow rates. Suitable for tissue culture applications, these filters provide low protein binding and low extractables. Reusable models offer convenience and cumulative cost savings over time, with cleaning performed via autoclaving. Plastic construction imbues these filters with reliable durability.
