The Yamato RE-212-CW2A is a complete 220 V rotary-evaporator system from Yamato's RE202/212 · REV202M/212M digital platform, configured with Set C glassware and a Water bath BM-312-A (5 L). A DC brushless (simple servo) motor turns the flask across 5–315 rpm (encoder dial, digital display) with forward/reverse/auto inversion; the double-corrugated-tube condenser (0.143 m²) handles up to 23 mL/min. An external aspirator or vacuum pump provides vacuum; the VR102S controller is optional.
