Re-202-A Rotary Evaporator, Bo-302-A Oil Bath (5L), Glassware B Overview
The RE202A Rotary Evaporator with BO302A Oil Bath and Glassware Set B is a complete distillation system from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. This rotary evaporator pairs a 5 L oil bath rated from RT +10°C to 180°C with a vertical-condenser glassware set, delivering evaporation rates up to 23 ml/min.
Construction uses chromium-free electrogalvanized steel with a baked-on finish, anodized aluminum, and fiberglass-reinforced polybutylene terephthalate resin. A DC brushless simple-servo motor drives rotation across 5–315 rpm, while the double corrugated-tube condenser provides 0.143 m² of cooling surface. Manual spring-loaded jack lift reaches 200 mm with stepless, one-touch locking.
Operating on 100–115V, 50/60 Hz at 1 A, the system fits a 36 × 36 × 27 in footprint and weighs 90 lbs. Set inversion lets technicians mount glassware and bath on either side to suit handedness or bench layout. Country of origin is Switzerland.
Key Features
- Wide rotation range: DC brushless simple-servo motor drives 5–315 rpm with forward, reverse, and auto-inversion modes.
- Set inversion function: glassware and oil bath mount on the left or right side to match the operator's dominant hand and installation location.
- Manual slide jack: spring-loaded lift reaches a 200 mm maximum height with stepless adjustment and one-touch lock.
- Glassware Set B: standard vertical condenser is space-saving, allowing three units to fit in a standard fume hood.
- Condenser insulation kit: standard equipment suppresses condensation on the condenser surface.
- Layered safety: motor overload, over-/low-voltage, speed-sensor-error, and bath overheat protection with independent temperature upper-limit error and overcurrent fuse.
How to Choose the Right Rotary Evaporator
Selecting a rotary evaporator means matching bath capacity, temperature reach, and control style to your solvents and throughput. Use the criteria below to confirm this system fits your workflow before ordering.
- Bath capacity and temperature: the 5 L oil bath spans RT +10°C to 180°C, suited to higher-boiling solvents that exceed water-bath limits.
- Flask compatibility: evaporation flasks from 50–2000 ml and receiving flasks from 100–2000 ml accommodate small samples through batch distillations.
- Control type: digital speed display with control knob and eight brightness levels offers repeatable, readable rotation settings.
- Voltage and site power: confirm a 100–115V, 50/60 Hz circuit, since this configuration ships as the 115V model.
- Seal chemistry: FKM seals are standard; specify PTFE for ketone or ether solvents.
- Footprint: the space-saving Set B condenser lets three units share a standard fume hood.
