The device presents itself in a clear design, simple and modern at the same time. The sturdy housing shows up in white, a good contrast to the black hoses. The switches and controls are located on the front, thus a comfortable operation is guaranteed.
A digital vacuum meter provides information for the current system pressure, a fine adjustment valve allows the stepless regulation of the vacuum. The safety vent valve allows evaporation to be stopped by venting the piston, and a separate on/off switch for the pump is provided.
The model is equipped with an inert gas connection, and is delivered fully assembled. You have safe control over the evaporation, even with low boiling solvents you are offered high recovery rates.
The closed system arrangement enables gentle distillation, a fine adjustment valve allows stepless regulation of the vacuum. When the desired vacuum is reached, the fine adjustment valve can be closed and the pump switched off. The unit operates extremely quietly and is maintenance-free.
