A simple evaporator for flasks under reduced pressure was designed which needed no rotating joint. It moves in a rotary oscillation at an angle of about 110°, and an outlet is connected with a condenser by a rubber tube. The angle of rotation can be increased by combining the oscillator with a pair of gears, but the simplest one may be useful for usual purpose of evaporation with minimum foaming or bumping in the flasks when it is oscillated about 150 times per minute.
