The Yamato RE-202-A is the 115 V rotary-evaporator main unit of Yamato's current RE202/212 · REV202M/212M digital platform — the motorized drive head with digital speed readout and manual-balance hand-lift jack, supplied without glass set or heating bath so you configure those to the application. A DC brushless (simple servo) motor turns the flask across 5–315 rpm with forward/reverse/auto-inversion on an encoder dial with digital display. Vacuum is supplied by an external aspirator or pump; the VR102S controller is optional.
