For all Hei-VAP Expert Control/Hei-VAP Ultimate Control models.
Three-stage diaphragm pump is made from chemical-resistant materials. High suction capacity of 1,7 m³/h for fastest evacuation. Achieves an ultimate vacuum of 2 mbar. Even if the gas ballast valve is open an excellent ultimate vacuum is reached when working with easily condenserable vapors. This makes distilling high boiling point solvents such as DMF or DMSO possible at low bath temperatures. Can be combined with a condenser.
