Cytiva's Whatman Puradisc line is a comprehensive syringe filter portfolio used in a variety of applications. Cytiva also offers high-performance GD/X syringe filters with a multi-layer glass fiber prefilter for filtering larger volumes of harder-to-filter samples.

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.
