Cellulose nitrate membrane filters

Cellulose nitrate membranes have high mechanical strength, high flexibility, high flow rates, and low extractable levels. These features make the membrane a good choice for trace element analysis applications. However, they also exhibit high protein binding so are unsuitable for protein recovery applications.
