which membrane filter design

网页If the membrane does not have a substrate, it is bio-directional and either side can be used as the inlet. If it has a substrate, the substrate layer will be more coarse and ridged than the membrane side. The membrane side would be the inlet and the coarse substrate side the outlet. The solvent should enter the inlet side of the membrane first.
