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.

The RV-5A Rotary Evaporator delivers precise, efficient solvent evaporation under reduced pressure for chemical, pharmaceutical, and research laboratory applications requiring a 5L-scale system with professional-grade temperature accuracy and operational convenience. At the core of the RV-5A is a PID temperature controller providing ±1°C bath stability across a range of RT+5°C to 99°C (water bath) or optionally to 180°C (oil bath) — ensuring reproducible evaporation conditions for consistent solvent recovery and sample concentration results. Combined with a 20–140 rpm rotation range, 8 mbar ultimate vacuum, automatic lift mechanism, PTFE and Teflon coating sealing system, and a 2 L/h maximum evaporation rate, the RV-5A is the mid-scale rotary evaporator of choice for laboratories demanding accuracy, chemical resistance, and ease of operation in a compact 860 × 410 × 1120 mm footprint.

The RV-20A Rotary Evaporator is engineered for medium-to-large scale solvent evaporation in chemical, pharmaceutical, and industrial laboratory environments where batch volume, processing throughput, and structural robustness must match the demands of pilot-scale and high-volume production-adjacent operations. With a 20L rotary flask, 10L collection bottle, 7 L/h maximum evaporation rate, and a 1.29 m² condenser area — the largest in the mid-range RV Series — the RV-20A delivers serious processing capacity backed by PID temperature precision (±1°C), 8 mbar ultimate vacuum, and an aluminum alloy bracket providing the structural strength required to support the greater mechanical loads of 20L-scale glassware and solvent volumes.

The RV-50A Rotary Evaporator is the flagship high-capacity unit of the RV Series — purpose-built for large-scale solvent evaporation, industrial chemical processing, pharmaceutical production support, and large-volume research operations where no smaller rotary evaporator format can meet the throughput and batch volume requirements. With a 50L rotary flask, 20L collection bottle, 9 L/h maximum evaporation rate, and a 1.75 m² condenser area — the largest in the RV Series — the RV-50A delivers production-adjacent processing capability backed by PID temperature precision (±1°C), 8 mbar ultimate vacuum, 5300W high-capacity heating, and an aluminum alloy bracket engineered for the structural demands of 50L-scale glassware and solvent loads.
