Membrane filtering device training device

This device is a small membrane filtration device for laboratory, which can be widely used in solution or gas material separation, concentration and purity (polymer, cells, microorganisms, viruses, water colloids, impurities, rust, bacteria, algae, etc. To. It uses a thin film with ability to separate the medium, and the membrane wall densely distributes micropores. Under a cert--n pressure, the raw solution is filtered by the side of the membrane, the solvent, and the small molecule of the small molecule, and the large molecular solution is cut off by the membrane, so as to achieve the purpose of material separation and concentration. The membrane separation process is the dynamic filtering process. The solution of the macromolecular solution is blocked by the membrane wall. As the concentrated liquid flows out of the membrane component, the membrane is not easily blocked and can be used continuously for a long time. The filtering process can be run at room temperature and low pressure, with no phase change and efficient energy saving.
