Re-212-A Rotary Evaporator, Bm-312-A Water Bath (5L), Glassware B Overview
The Yamato Scientific RE212A Rotary Evaporator system is a complete distillation setup pairing the RE212 main unit with Glassware Set B and a BM312A water bath rated from RT +10°C to 90°C. LabSupplies.com, an authorized dealer, supplies this 5 L 220V configuration for solvent recovery and concentration work.
Glassware Set B uses a vertical condenser with a 0.143 m² double corrugated cooling tube, keeping the footprint compact enough that three units fit one standard fume hood. A spring-loaded manual jack delivers stepless lift to 200 mm with one-touch lock. Set inversion lets you mount glassware and bath on either side.
Power draws 200–230V single-phase, 50/60 Hz at 1 A through a round terminal. Exterior panels use chromium-free electrogalvanized steel with a baked-on finish, plus anodized aluminum and glass-fiber-reinforced polybutylene terephthalate. The unit weighs 90 lbs, ships at 36 × 36 × 27 in, and is manufactured in Switzerland.
Key Features
- Rotation control: Digital speed display with control knob, 5–315 rpm, plus forward, reverse, and auto-inversion modes.
- Evaporation capacity: Up to 23 ml/min, with a double corrugated condenser providing 0.143 m² of cooling surface.
- Manual slide jack: Spring-loaded stepless lift to 200 mm maximum with one-touch lock for fast flask exchange.
- Set inversion design: Glassware and bath mount on either the left or right to suit handedness and bench layout.
- Flask compatibility: Accepts 50–2000 ml evaporation flasks and 100–2000 ml receiving flasks; FKM seal standard, PTFE recommended for ketones and ethers.
- Layered safety: Motor overload, over/low-voltage and speed-sensor-error protection, with bath overheat prevention and an overcurrent fuse.
How to Choose the Right Rotary Evaporator
Matching a rotary evaporator to your workflow means weighing throughput, solvent chemistry, and bench constraints . Use the criteria below to confirm this RE212A system fits your lab.
- Capacity: A 5 L bath and 50–2000 ml flask range suit routine concentration and recovery batches; size the receiving flask to your distillate volume.
- Temperature range: The BM312A bath covers RT +10°C to 90°C at ±1.0°C, which determines the solvents you can drive off efficiently.
- Control type: Digital speed display with auto-inversion supports reproducible, hands-free operation across repetitive runs.
- Voltage: This configuration is wired for 200–230V single-phase, 50/60 Hz; verify your circuit before installation.
- Footprint: The space-saving vertical condenser lets three units share one standard fume hood where bench area is limited.
- Seal chemistry: FKM ships standard; specify PTFE if your protocols use ketone or ether solvents.
