RE-202-A Rotary Evaporator, BM-302-A Water Bath (5L), Glassware B Overview
Set B uses a space-saving vertical condenser, letting three units fit inside a standard fume hood. A double corrugated-tube condenser delivers 0.143 m² of cooling surface, while the DC brushless simple-servo motor drives rotation from 5 to 315 rpm. Evaporation reaches up to 23 ml/min, and an auto-inversion mode runs forward or reverse cycling.
Key Features
- Manual spring-loaded jack: stepless height adjustment to a 200 mm maximum lift with one-touch lock for fast flask raising and lowering.
- Digital speed control: rotation from 5 to 315 rpm shown on a display with control knob and eight brightness levels.
- Three rotation modes: forward, reverse, and auto-inversion cover varied distillation and bumping-prevention needs.
- Condenser insulation kit: supplied as standard to suppress condensation forming on the condenser surface.
How to Choose the Right Rotary Evaporator
Selecting a rotary evaporator means matching bath temperature, flask capacity, and site power to your solvent workload. Use the criteria below to confirm this RE202A system fits your process.
- Bath temperature range: the BM302A water bath covers RT +10°C to 90°C with ±1.0°C accuracy, suitable for water-compatible solvent recovery; high-boiling solvents may need an oil bath.
- Flask capacity: the system accepts evaporation flasks of 50–2000 ml and receiving flasks of 100–2000 ml, so confirm your typical batch volume falls in range.
- Voltage and site power: this unit is 100–115V, 50/60 Hz; verify your bench circuit before installation.
- Footprint: Glassware Set B's vertical condenser is space-saving, letting three units share a standard fume hood.
- Solvent chemistry: the FKM vacuum seal is standard, with a PTFE seal recommended for ketone or ether solvents.
