The RV-21A Rotary Evaporator is the compact, small-scale entry in the RV Series — engineered for academic research laboratories, small-scale chemical sample processing facilities, and analytical laboratories requiring efficient, precise solvent evaporation in a space-conscious benchtop format. Combining a DC brushless motor with a 20–300 rpm rotation speed range, 8 mbar ultimate vacuum capability, automatic lifting mechanism, and PTFE vacuum sealing — all housed in a compact structure — the RV-21A delivers reliable reduced-pressure evaporation performance for 1L rotary flask applications. With a 1000W heating bath, vertical condenser with 1.7L capacity, and 1L collection bottle, the RV-21A is purpose-built for small-batch solvent recovery, chemical sample concentration, and laboratory-scale distillation.
