33mm PES Sterile Syringe filter with pore diameter 0.2um needle filter

Sterile Syringe Filter is a device for intercepting solid particles in liquid or gas through the principle of physical filtration. The principle of syringe filter is based on physical filtration, which intercepts impurities in the sample through the microporous structure of the filter membrane. When a liquid or gas sample is pushed through a syringe into the membrane, the membrane physically intercepts particles larger than the pore size by virtue of its tiny pore size. In addition, some filter membrane materials can also adsorb specific molecules or compounds in the sample to achieve the goal of purification.
