Biotechnology is developing rapidly in China. Biological products, as an important part of modern medicine and biotechnology, play a very important role in the prevention and treatment of diseases, protection and improvement of people's health. Biological products need to go through multiple biological processes, purification analysis technology, to get the target. Physical filtering, with its natural advantages, can creatively complete the task, is an indispensable process for biological products.
Biological products, with microorganisms, parasites, animal toxins, biological tissue as the starting material, most of the source, production process and other uncontrollable factors are too much. The types and quantities of impurities expressed by biological substances cannot be accurately predicted. The number and quantity of substances remaining in the original solution are usually controlled only by the items specified in the quality standards, while other impurities are difficult to be fully controlled. Comprehensive control is the basis of sound production.
