Re-212-A Rotary Evaporator, Bm-312-A Water Bath (5L), Glassware A Overview
The Re-212-A Rotary Evaporator, Bm-312-A Water Bath (5L), Glassware A is a complete RE212A rotary evaporator system from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. This set pairs the RE212A main unit with Glassware Set A and a 5 L BM312A water bath heating to 90°C. Solvent recovery reaches up to 23 ml/min across a 5–315 rpm rotation range.
Glassware Set A uses a traditional diagonal condenser with a double corrugated tube delivering 0.143 m² of cooling surface, intended for use with an external chiller. A DC brushless servo motor drives forward, reverse, and auto-inversion modes. Manual spring-loaded jack travel reaches 200 mm with stepless, one-touch lock positioning. Set inversion lets glassware and bath mount left or right.
Power input is 200–230V single-phase, 50/60 Hz at 1 A through a round terminal without plug. The unit ships at 90 lbs with a 36 × 36 × 27 in carton footprint and originates from Switzerland. Exterior construction uses chromium-free electrogalvanized steel with baked-on finish, anodized aluminum, and glass-fiber-reinforced polybutylene terephthalate resin.
Key Features
- Glassware Set A: traditional diagonal condenser with double corrugated tube and 0.143 m² cooling surface, designed for chiller-assisted condensation.
- Rotation control: 5–315 rpm with forward, reverse, and auto-inversion modes, driven by a DC brushless simple-servo motor.
- Manual lift jack: spring-loaded mechanism with 200 mm stepless travel and one-touch lock for fast flask raising.
- Set inversion design: glassware and bath mount on either side to suit dominant hand and bench location.
- BM312A water bath: 5 L capacity (Φ240 × H119 mm), RT +10°C to 90°C, ±1.0°C accuracy, with 2A service outlet.
- Layered safety: motor overload, over/low-voltage and speed-sensor protection, plus bath overheat prevention, upper-limit error detection, and overcurrent fuse.
How to Choose the Right Rotary Evaporator
Selecting a rotary evaporator means matching solvent load, throughput, and site power to the right glassware and bath configuration. Use these axes to confirm the RE212A system fits your workflow.
- Capacity: evaporation flasks from 50–2000 ml and receiving flasks from 100–2000 ml define batch size; confirm your typical volumes fall in range.
- Bath temperature: the BM312A heats from RT +10°C to 90°C at ±1.0°C, suitable for water-bath distillation of common solvents.
- Condenser type: Glassware Set A uses a diagonal condenser meant to run with an external chiller, so factor in chiller availability.
- Voltage and power: this set requires 200–230V single-phase, 50/60 Hz; verify bench circuits match the round-terminal input.
- Footprint and handedness: set inversion allows left or right mounting, so plan bench space against the 36 × 36 × 27 in shipping size.
- Solvent chemistry: FKM vacuum seals ship standard, with PTFE recommended for ketone or ether solvents.
