Vacuum filtration is a common laboratory equipment, in the chromatographic analysis, for the removal of the column life and the accuracy of the system detection of impurities, has an important role. In the filtration process it is the liquid degassing effect is also obvious. The equipment with different purposes of the filter membrane has been applied in the weight analysis, chromatography, colloid separation and other tests.
