Vacuum Apparatus - Scientific and Laboratory Glass

 Vacuum apparatus in labs is used to generate, maintain, and manipulate pressures below the ambient atmosphere. Vacuum equipment has many uses in labs, including:

• Suction - vacuum pumps can provide suction to drive the filtration or aspiration of liquid or suspended samples.
• Solvent evaporation - vacuum pumps can control or induce solvent evaporation by reducing vapor pressure. This is used in gel dryers, rotary evaporators, ovens, and concentrators.
• Vacuum filtration -  vacuum systems can be used for vacuum filtration, solvent removal, vacuum distillations, and rotary evaporation.
• Inert gas purging - many common lab procedures require vacuum conditions, such as inert gas purging.
