Re-212-A Rotary Evaporator, Bm-312-A Oil Bath (5L), Glassware B Overview
The Re-212-A Rotary Evaporator, Bm-312-A Oil Bath (5L), Glassware B pairs the Yamato Scientific RE212A main unit with a 5 L oil bath and vertical-condenser Glassware Set B. Distillation runs from room temperature to a 180°C bath ceiling at speeds of 5 to 315 rpm. LabSupplies.com supplies this complete system as an authorized Yamato Scientific dealer.
Exterior panels use chromium-free electrogalvanized steel with a baked-on finish, anodized aluminum, and fiberglass-reinforced polybutylene terephthalate resin. A DC brushless servo motor drives rotation, while the double corrugated-tube condenser delivers 0.143 m² of cooling surface. Manual spring-loaded jack lifts the flask up to 200 mm with stepless adjustment and one-touch lock.
Power draws 200–230V single-phase at 50/60 Hz through a round terminal without a plug. Footprint measures 36 × 36 × 27 inches, and the packed system weighs 90 lbs. Manufactured in Switzerland, the unit includes motor overload, over-/low-voltage, and speed-sensor-error protection as standard.
Key Features
- Set inversion: glassware and oil bath mount on either side, left or right, to suit a technician's dominant hand and the installation location.
- Rotation control: forward, reverse, and auto-inversion modes with a digital speed display and control knob offering 8 brightness levels.
- Slide jack lift: manual spring-loaded mechanism raises the flask to a 200 mm maximum height with stepless, one-touch locking.
- Condenser insulation kit: supplied as standard to suppress condensation on the condenser surface.
- Evaporation throughput: capacity up to 23 ml/min, accepting evaporation flasks from 50 to 2000 ml and receiving flasks from 100 to 2000 ml.
- Solvent-ready sealing: FKM vacuum seal fitted as standard, with PTFE recommended for ketone and ether solvents.
How to Choose the Right Rotary Evaporator
Matching a rotary evaporator to your workflow comes down to bath capacity, temperature reach, control style, and site power. Weigh each axis against the solvents and flask sizes your lab runs most.
- Bath capacity and flask range: a 5 L oil bath supports evaporation flasks from 50 to 2000 ml, so confirm your typical batch volume fits the working range.
- Temperature range: this oil bath spans RT +10°C to 180°C, covering higher-boiling solvents that a water bath cannot reach.
- Control type: a digital speed display with auto-inversion suits labs that want repeatable, hands-off operation across forward and reverse cycles.
- Voltage and power: verify your bench supports 200–230V single-phase, 50/60 Hz before ordering, since the terminal ships without a plug.
- Footprint: Glassware Set B is space-saving — three units fit in a standard fume hood — so plan around the 36 × 36 × 27 inch envelope.
- Solvent compatibility: choose the PTFE vacuum seal upgrade when distilling ketones or ethers; FKM covers general-purpose use.

Frequently Asked Questions
What temperature range does the BO312A oil bath cover?
The BO312A oil bath operates from RT +10°C up to 180°C with ±2.0°C accuracy. This higher ceiling supports solvents and applications beyond the reach of a water bath.
What bath capacity and flask sizes does this system accept?
The oil bath holds approximately 5 L (Φ240 × H119 mm). It accepts evaporation flasks from 50 to 2000 ml and receiving flasks from 100 to 2000 ml, with an optional reducer for smaller flasks.
What voltage and power supply does the RE212A require?
This configuration runs on 200–230V single-phase, 50/60 Hz at 1 A. The supply uses a round terminal and ships without a plug, so confirm your bench power before installation.
What rotation speed and modes are available?
Rotation runs from 5 to 315 rpm via a DC brushless servo motor. Forward, reverse, and auto-inversion modes are selectable, with speed set through a digital display and control knob.
Which vacuum seal is recommended for aggressive solvents?
FKM is the standard vacuum seal for general-purpose distillation. Yamato recommends a PTFE seal when working with ketone or ether solvents for improved chemical compatibility.
What is included in Glassware Set B?
Glassware Set B provides a standard vertical condenser with a double corrugated-tube design offering 0.143 m² of cooling surface. The vertical layout is space-saving, allowing three units to fit in a standard fume hood.
