Rotary Evaporator (Main Unit) Digital With Vacuum Regulator Overview
The Rotary Evaporator (Main Unit) Digital With Vacuum Regulator (model REV202M) is a benchtop rotary evaporator from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. Rotation spans 5–315 rpm with evaporation throughput up to 23 ml/min, supporting evaporation flasks from 50 to 2000 ml and receiving flasks from 100 to 2000 ml.
Engineering centers on a DC brushless servo motor driving forward, reverse, and auto-inversion modes. A double corrugated condenser provides 0.143 m² of cooling surface, while the manual spring-loaded jack raises glassware to 200 mm with stepless, one-touch locking. FKM seals ship as standard; PTFE seals are recommended for ketone and ether solvents.
Operation runs across a 5–35°C ambient range on a 100–115V, 50/60 Hz, 1 A supply. Net weight is roughly 10.5 kg, keeping the unit manageable on a standard bench. Manufactured in China, the system integrates a VR-102S vacuum controller with a 2.3-inch color LCD and a 0–1013 hPa setting range.
Key Features
- Digital rotation control: 5–315 rpm with a control knob, digital speed display (8 brightness levels), and forward, reverse, and auto-inversion modes driven by a DC brushless servo motor.
- Integrated VR-102S vacuum controller: 2.3-inch color LCD, 0–1013 hPa setting range, and manual, gradient, and auto modes with hold, auto-leak, and auto-clean functions.
- Manual spring-loaded lift: raises glassware to a 200 mm maximum height with stepless adjustment and one-touch locking.
- Double corrugated condenser: delivers 0.143 m² of cooling surface for efficient solvent recovery.
- Configurable set inversion: glassware and bath mount on either the left or right side to suit bench layout.
- Layered safety: motor overload, over-/low-voltage, and speed-sensor-error protection, plus controller pressure-sensor, leak, and high-pressure error detection with auto-leak on fault.
How to Choose the Right Rotary Evaporator
Selecting a rotary evaporator comes down to matching distillation volume, solvent chemistry, and bench power to your daily workflow. Review these axes .
- Capacity: confirm flask compatibility against your batch sizes — this unit accepts 50–2000 ml evaporation flasks and 100–2000 ml receiving flasks, with an optional reducer for smaller flasks.
- Rotation range: a 5–315 rpm range with forward, reverse, and auto-inversion modes covers gentle concentration through faster evaporation up to 23 ml/min.
- Control type: digital speed control and an integrated vacuum controller add repeatability through manual, gradient, and auto pressure profiles versus manual-only setups.
- Voltage: choose the 115V (REV202M) or 220V (REV212M) build to match your facility power and avoid step-up transformers.
- Solvent compatibility: standard FKM seals suit most work, while PTFE seals are advised for ketone and ether solvents.
- Footprint and lift: a roughly 10.5 kg unit with a 200 mm manual jack fits standard benches and simplifies flask changes.
