Flat Sheet Membrane Chart
Note: This chart shows preliminary information, as GE is constantly doing research and developing new
membranes. As a result, new membranes will become available and old may be discontinued.

Within most membrane designations, several different membrane elements are available, that are differentiated by numbers after the membrane designation mentioned here.
These membranes are available in the following configurations:
1. pre-cut flat sheets for Sepa test cells
2. flat sheets of 1 ft² each (924 cm²) in 12”x12” size
3. spiral wound modules
Contact GE to know the construction size available for each polymer type.
Flat sheet membranes are not available in large quantities except under special arrangements.
