Büchi Labortechnik AG V513 Vacuum Pump

The Büchi Labortechnik AG V-513 Vacuum Pump, paired with the Buchi V-721 Vacuum Controller, is a compact vacuum system designed for laboratory distillation and evaporation work in Buchi Rotavapor configurations. The V-513 combines a diaphragm pump with the V-721 control unit to provide adjustable, monitored vacuum levels, enabling precise boiling-point control and improved heat efficiency during rotary evaporation. In common configurations, the V-513 vacuum system includes a Woulff bottle for gas-liquid separation and an emission condenser to minimize vapor escape, helping keep the work area cleaner and safer. Described in retailer listings as a complete V-513 kit with the V-721 controller, this setup is compatible with Buchi vacuum accessories and is used for applications requiring reliable, controlled vacuum in chemical laboratories and educational settings, with the V-721 controller offering straightforward adjustment and monitoring alongside the pump.
