Ultrafiltration: Flat Sheet Membranes


Synder offers flat sheet Ultrafiltration membranes for all membrane types that are currently available. Standard sizes are 12″ x 12″ and 1m x 1m, but custom sizes and flat sheet rolls are also available upon request. Flat sheet membranes are commonly purchased for small-scale lab testing to determine which cut-off is most appropriate for each given application, as they are easy to install and use with a test unit.

Ultrafiltration membranes have a molecular weight cut-off range of 1,000 to 500,000Da. These types of membranes have the ability to reject large macromolecules and proteins, and are widely applied throughout the dairy, food & beverage, biotech, and pharmaceutical industries.

In certain high solids applications, flat sheet ultrafiltration membranes provide excellent performance (membrane life vs. operating cost). Unlike hollow fiber membranes, flat sheet ultrafiltration membranes have a strong support material in which the polymeric membrane layer is rooted that increases physical durability substantially.

Synder Filtration offers a comprehensive line of both dry and wet ultrafiltration flat sheet membrane available in a wide range of molecular weight cut-offs. With product sizes ranging from one square foot to thousands of linear feet, Synder can supply UF flat sheet membranes for process research, pilot testing, spiral element winding, and for use in plate & frame membrane systems.
