For use with the Rotary Vacuum Evaporator, this unit boasts great features and is highly recommended for use in an area lacking water service or where it is difficult to obtain constant water pressure. It has a transparent lid cover that makes it possible to check the water condition in the bath. Bath structure is made to be removed and cleaned easily. Since the unit circulates the water in the aspirator at constant pressure by pump, it assures constant suction. The unit is capable of displacement levels of 16/19L/min 50/60Hz (at 6°C water temp.) and an ultimate vacuum of 30Pa/7mmHg(5°C)-4266Pa/32mmHg(30°C). The 150W induction motor provides power and the unit also has a check valve and thermal protector for safety.
