A: Vacuum filtration, also known as “suction filtration,” is an application that uses vacuum-generating equipment, such as vacuum pumps, to accelerate the separation of solid-liquid mixtures.

The equipment used typically includes a Buchner funnel, a filtration flask, and a vacuum pump. When selecting an appropriate micro vacuum pump, two main factors should be considered:
(1) Consider the pressure resistance of the funnel and filter paper to determine the required vacuum level for the pump.
(2) Consider the power supply for the application scenario. For example, when used in the field without mains power, a low-power micro vacuum pump powered by batteries can be chosen.
Furthermore, when using a micro vacuum pump in this scenario, customers need to prevent liquids and other solid impurities from entering the pump chamber, as this can affect the pump’s service life.
