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.
