Main Steps of Vacuum Filtration

Vacuum filtration is a technique which could separate the solid from the liquid. The following steps could keep everything running normally:

First of all, put the filter paper into the Buchner funnel and try to make an accurate match. If the diameter of the filter paper is too large, cut it to the proper shape by scissors.

Second, put the rubber plug on the flask opening. There should be a hole in the center of the plug so that the funnel could get into the flask closely and safely in case hitting the glass.

Third, put the funnel into the plug. Otherwise, put them together as an entity and then connect it to the flask.

Then, use the rubber tubing to connect the side nozzle and the vacuum pump.

Next, pour the mixture of the solid and liquid into the Buchner funnel through the filter paper.

Finally the solid would be extracted while the liquid would be sucked into the flask underneath by the vacuum.

This technology could also be applied in syntheses to produce the solid in the reaction or analysis including the gravimetric analysis of suspended solids.
