Abstract
There are a variety of tasks in organic chemistry which require provision of a vacuum source. However, different tasks will require different levels of vacuum and more than one type of vacuum source will be needed to service all the requirements of the lab. We can split vacuum supplies loosely into two categories: low vacuum, being 1–50mmHg and high vacuum being below 1mmHg. A low vacuum source is valuable for such tasks as vacuum filtration, operation of rotary evaporators and vacuum distillation of relatively volatile liquids. High vacuum is required for serving inert gas line manifolds, vacuum distillations and drying solids by removing traces of solvent or moisture from them.
