A laboratory vacuum pump removes air or gas from a closed system to create negative pressure, supporting processes such as filtration, rotary evaporation, vacuum drying, degassing, and vacuum ovens. Oil-free vacuum pumps are preferred where sample contamination from oil vapor must be avoided, while chemical resistant vacuum pumps are built to handle corrosive vapors generated during solvent evaporation or acid digestion. Vacuum pumps help laboratories speed up filtration, remove dissolved gases from liquids, and maintain controlled low-pressure environments for sensitive samples. They are widely used across chemistry, pharmaceutical, biotechnology, and quality-control laboratories. Axibio offers oil-free and chemical resistant vacuum pumps suited to different laboratory workflows.
