Dialysis membrane is a separation membrane driven by concentration difference. According to the particle size of the separated solute, the dialysis membrane is required to have appropriate micropores with uniform pore size. Filtration is a method to separate solid substances insoluble in liquid from liquid. According to the properties of each component in the mixture, different methods such as atmospheric filtration, decompression filtration or thermal filtration can be adopted. According to different methods and objects, the equipment used is also different. STEMart offers a variety of membrane types, filter diameters and membrane porosity to meet almost all applications.

Lab Dialysis
We provide cellulose ester (CE) regenerated cellulose (RC) products. Cellulose ester (CE) can be used in a variety of MWCO to provide better molecular separation for more challenging and critical dialysis applications. Regenerated cellulose (RC) has better chemical compatibility, pH and temperature tolerance.
There are many sizes, MWCO (100 – 500, 500-1000, 1000, 2000, 3500, 3500 – 5000, 5000, 6000-8000, 8000, 8000-10000, 10000, 12000-14000, 14000, 15000, 10000-200001000000, 20000, 25000, 300000, 50000, 1000000) and formats available for laboratory scale dialysis and large-capacity process scale dialysis. See the Dialysis Membranes, Dialysis Systems and Dialysis Accessories for more products.
