The vacuum filtration is a device that realizes solid-separation with vacuum negative pressure as the driving force. In terms of the structure, the filtration section is arranged along the horizontal length direction, which can continuously complete filtration, washing, drying and other operations. It is mainly used for solid-liquid separation, liquid clarification, sterilizing, removing impurities and also for room temperature reaction.
Background and Rational of vacuum filtration
Traditionally, the separation is usually carried out by a conical funnel with a filter paper of different sizes, through which the liquid is pushed through the filter membrane by natural penetration and gravity. However there exist a great disadvantages. The pore size of the filter membrane will cause great resistance to the liquid, resulting in an extremely slow filtration speed.

Compared with traditional separation method, vacuum filtration can help greatly improve the filtration efficiency and save time.
