semipermeable membrane
a membrane that allows the passage of some molecules but not others. Cell membranes (see cell) are semipermeable. Semipermeable membranes are used clinically in haemodialysis for patients with kidney failure.

* * *

a membrane that is freely traversed by solvent, such as water, but which permits the passage of only certain solutes.
