vacuum filtration setup laboratory china

Filtration chemistry Britannica.com

Centrifuges containing a bowl with a porous filter medium may be considered as filters in which gravitational force is replaced by centrifugal force many times greater than gravity. If a laboratory filtration is difficult a partial vacuum is usually applied to the container below the filter medium to increase the rate of filtration.

Using rubber tubing, the filter flask is connected to a trap, which in turn is connected to an aspirator, which provides the vacuum. After the filtrate has been collected, pass a small amount of pure solvent through the filter to wash the residue. If the weight of the residue must be obtained, heat a filter crucible in the oven to dry it.

Filtration Wikipedia

Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the appliion, either one or both of the components may be isolated. Filtration, as a physical operation is very important in chemistry for the separation of materials of different chemical composition.
