The Working Principle and Characteristics of Vacuum Filtration

Vacuum Filtration mainly puts pressure on the filtering mixture of solid and liquid material in order to pass the liquid through the filter. This technology is the practical application of Bernoulli’s Principle – Pressure Reduction and is widely applied in the production of medium and buffer materials.

It is a kind of chemical laboratory technology which could permit the higher filtration rate than normal filter process where the pressure gradient works so that the processing time could be shortened. The advantage of this filtration could provide the variable rate according to the intensity of the vacuum pumps, which is mainly applied in microbiology and laboratory procedures and refers to collect particles (bacteria, sediment etc.) from the liquid suspension.

The important performances of vacuum filtration include low binding, quick flow speed, and high throughput. In addition, it could eliminate the risk of pollution, leakage, and waste of time. Moreover, it could also improve the security and ergonomics through removing repetitive lifting and pouring.

But please notice that the excess vacuum is forbidden in case the fracture of the filter paper. The simplified working procedure and maximum filtration is the ultimate pursuit of vacuum filtration.
