Re-212-A Rotary Evaporator, Bm-312-A Water Bath (5L), Glassware C Overview
The RE212A Rotary Evaporator with BM312A Water Bath and Glassware Set C is a complete distillation system from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. This rotary evaporator pairs a DC brushless drive with a 5 L heated water bath spanning RT +10°C to 90°C, delivering evaporation rates up to 23 ml/min across a 5–315 rpm range.
Glassware Set C uses a cold-finger vertical condenser matched to volatile, low-boiling-point solvents. Double corrugated tube condenser geometry provides 0.143 m² of cooling surface, while a standard condenser insulation kit suppresses surface condensation. A manual spring-loaded jack lifts the assembly up to 200 mm with stepless, one-touch locking.
Power input is 200–230V single-phase, 50/60 Hz, 1 A, supplied without a plug via round terminals. Exterior panels use chromium-free electrogalvanized steel with a baked-on finish plus anodized aluminum and glass-fiber-reinforced PBT resin. Shipping weight is 90 lbs with a 36 × 36 × 27 in footprint; country of origin is CH.
Key Features
- Set inversion function: glassware and bath mount on either the left or right side to suit the operator's dominant hand and bench layout.
- Rotation control: 5–315 rpm with forward, reverse, and auto-inversion modes, shown on a digital display with an 8-level brightness knob.
- Manual lift jack: spring-loaded slide mechanism raises the flask up to 200 mm with stepless, one-touch lock height adjustment.
- Glassware Set C: cold-finger vertical condenser with 0.143 m² double corrugated cooling surface, plus a standard condenser insulation kit.
- Flask compatibility: accepts 50–2000 ml evaporation flasks and 100–2000 ml receiving flasks, with an optional reducer for smaller flasks.
- Layered protection: motor overload, over/low-voltage, speed-sensor-error, and AC adapter short-circuit safeguards across the system.
How to Choose the Right Rotary Evaporator
Solvent volatility, throughput, and site power determine which rotary evaporator fits a given workflow. Match the bath, condenser, and electrical spec to your samples .
- Condenser type: a cold-finger vertical condenser, as in Glassware Set C, targets volatile and low-boiling-point solvents that escape standard coil designs.
- Bath capacity and temperature: the BM312A holds roughly 5 L and heats from RT +10°C to 90°C at ±1.0°C, sizing flasks and recovery rate accordingly.
- Rotation and evaporation rate: a 5–315 rpm range and up to 23 ml/min throughput govern how quickly batches concentrate.
- Voltage and site power: this system requires 200–230V single-phase, 50/60 Hz input wired to round terminals, so confirm available circuits.
- Seal chemistry: FKM is standard, while PTFE is recommended for ketone or ether solvents that attack standard seals.
- Footprint and inversion: the set-inversion feature lets you orient glassware and bath to fit bench space and operator handedness.
