LABOXACT® in use
The process in the rotary evaporator can be monitored reliably with the vacuum system LABOXACT. A closed, patented system arrangement enables gentle distillation and high recovery rates, even for low-boiling solvents. An fine-adjustment valve regulates the vacuum precisely. When the desired vacuum is reached, the fine- adjustment valve can be closed, or the pump can be switched off. If the rotary evaporator has leaks, then the fine-adjustment valve can be adjusted, allowing the pump to remove the leakage flow and maintain the boiling pressure. The safety vent valve makes it possible to interrupt evaporation at any time, by venting the rotary evaporator. Inert gas can be added via the special connection.
