As a technique to remove solid impurities from an organic solution or to isolate an organic solid in the lab, the filtration can be divided into two types: gravity filtration and vacuum filtration.
Scientists use gravity filtration to remove solid impurities from an organic liquid. You can find the impurity a drying agent or an undesired side product or leftover reactant when the filtration is done.that means gravity filtration is the way to collect the solid product.
Generally, vacuum filtration can be used for collecting a desired solid too. Do not use vacuum filtration to filter a solid from a liquid if it is the liquid that you want for your applications. If the liquid is a low boiling, vacuum filtration is not a good choice either, because, under the reduced pressure in the vacuum flask, the low boiling solvent that boils at the temperature of 125 ℃ or lower will boil off.

Working Mechanism of Diaphragm Vacuum Pump
Same as the general volume pump, the oil-free diaphragm vacuum pump is composed of the stator, rotor, rotor, cylinder block, motor, and other main parts. The rotor with the rotating plate is eccentrically installed in the fixed cylinder. When the rotor rotates at high speed, the four radial sliding rotating vanes in the rotor slot divides the pump cavity into four workrooms. Due to the action of centrifugal force, the rotor is close to the cylinder wall, separates the stator inlet and outlet, runs over and over again, carries on the variable volume, absorbs the gas and drains out from the exhaust port, so as to achieve the purpose of pumping.
