A membrane which limits the type of molecules which will pass through it is called a semi permeable membrane.

A semipermeable membrane is a membrane which can be biological or artificial, that will allow the movement of certain molecules through them by diffusion. Several factors such as pressure, concentration, temperature of the molecules on each side, and also the permeability of the membrane to each solute determine the rate of passage of the molecules.
