I. Overview of laboratory ultrafiltration/nanofiltration/reverse osmosis Model 1812 membrane separation systems

Laboratory multi-functional 1812 membrane separation system, mainly ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO) separation and purification, for the liquid with water as the solvent can be filtered, decolorized, desalted, purified, concentrated. According to the size of the molecular weight of the separated substance, the selection of the membrane, each membrane can be used alone or can be loaded with 3 kinds of the same membrane at the same time; It can separate substances ranging from 0.03μm to 100DALTON.

The multifunctional 1812 type membrane experimental equipment can be suitable for almost all 1812 membrane elements, convenient film change, we recommend the selection of standard membrane elements are imported health food grade products, with wide flow channel, pollution resistance, high temperature (80℃), long service life and other advantages, can also be selected according to customer needs strong acid, strong alkali membrane elements. The equipment has the advantages of easy cleaning, maintenance and large freedom of use. ,
