Hollow fiber ultrafiltration membrane is the most mature and advanced form of ultrafiltration technology. The outer diameter of the hollow fiber is 0.4-2.0mm, and the inner diameter is 0.3-1.4 mm. The wall of the hollow fiber tube is covered with micropores, and the pore size is expressed by the molecular weight that can intercept substances, and the molecular weight can reach thousands to hundreds of thousands. Ultrafiltration process has no phase transformation, and it is operated at normal temperature, which is especially suitable for the separation of heat-sensitive substances. It has good temperature resistance, acid and alkali resistance and oxidation resistance, and can be used continuously for a long time under the conditions of below 60℃ and pH 2-11.

Ultrafiltration centrifuge tube
