The Low-Pressure Flat Membrane Filtration Laboratory Machine is used for process experiments, such as concentration, separation, purification, clarification, and sterilization of feed liquids. Machine and test cell size etc can be customized according to experimental requirements. It can be replaced with microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, reverse osmosis membranes, and seawater/brackish water desalination membranes. It is suitable for the test and research of a variety of flat sheet membrane and the filtration of a small amount of feed liquid. It is widely used in Food and Beverage, Bio-pharm, plant extraction, cosmetics, chemical, Blood product, environmental protection and other fields.
