Characteristics Of The Dialyzer's Dialysis Membrane

Includes the membrane's effective area, thickness, density, pore size, surface water content and hydrophilicity.
1. The smaller the thickness and the larger the pore size, the easier it is for the solute to pass through the dialysis membrane.
2. The ultrastructure of the membrane pore channel is relatively regular, with low resistance, which is conducive to molecular permeation.
3. The product of the average pore size and the pore density determines the effective area of ​​the membrane, so the membrane area indicated on the dialyzer cannot directly reflect the effective area of ​​the membrane.
4. The charge and hydrophilicity of the membrane have a certain effect on the permeation of different solutes, so some dialysis membranes are made of a combination of different materials to improve the permeability and biocompatibility of the dialysis membrane to the solute.
