?:definition
  • Laboratory pumps designed to transfer or deliver fluids via a vacuum. These devices frequently consist of an oil-free rotary-vane-membrane pump with one or more channels and vacuum ports; they are usually made of chemically resistant (e.g., noncorrosive) plastic materials. Vacuum laboratory pumps are used to transfer aggressive vapors and gases; dedicated vacuum pumps providing specific ultimate vacuum levels (e.g., 2, 8, or 60 torricelli) and others intended for gel drying in electrophoresis procedures are also available.
