Use rotary vacuum evaporators for vacuum distillation of solvents at high or low temperatures, for vaccum drying of powders and solids, for evaporating heat-sensitive compounds, for degassing and for multiple extractions.

The pear-shaped evaporating flask is connected to a rotating glass steam duct. which runs through the drive units and into the stationary condenser. An easily inserted vacuum seal, is located in the condenser mouth.Vapors pass from the evaporator flask through the steam duct and into the condenser where they are condensed and collected in the receiving flask. An inlet feed tube at the upperend of the condenser is used for continuous feeding of liquid and to aerate the evaporator.

The rotating action of the evaporator increases the evaporation and insures even heating in the models with Microprocessor Digital Controlled Stainless Steel Boiling Water Bath.The solution to be concentrated is placed in the flasks, which rotates, mixing the solution and moving the liquid continuously upward.This action provides a large evaporating surface and in the water bath models. prevents over heating on the hot innerwall of the flask. By careful control of the speed of rotation and of the heat input, forming and bumping can be minimized. Evaporation with flask rotation speed 30-180 RPM.The flask can be removed easily by moving the motor assembly UP / DOWN by the manual / motorized mechanism by the Push of the button.

METREX Rotary Vacuum Evaporators are supplied with one liter evaporator and receiving flasks, a long steam duct, a condenser, an inlet feed tube, clamps a drive unit and a 3-wire rod with Electronic Digital Speed meter (optional). to show the speed of Evaporator Max. speed 180 RPM
