Re-202-A Rotary Evaporator, Bm-302-A Water Bath (5L), Glassware C Overview
The RE202CWA Rotary Evaporator System from Yamato Scientific is a complete distillation package pairing the RE202A main unit with a BM302A water bath and Glassware Set C. This 5 L system covers a rotation speed range of 5–315 rpm and an evaporation capacity up to 23 ml/min. LabSupplies.com supplies it as an authorized dealer.
Set C uses a cold-finger vertical condenser suited to volatile, low-boiling-point solvents. A double corrugated cooling tube delivers 0.143 m² of cooling surface, while the DC brushless simple-servo motor drives forward, reverse, and auto-inversion modes. Construction combines chromium-free electrogalvanized steel, anodized aluminum, and glass-fiber-reinforced PBT resin.
This configuration runs on 100–115V, 50/60 Hz at 1 A and ships in a 36 × 36 × 27 in footprint weighing roughly 90 lbs. Manufactured in Switzerland (CH), the system carries multiple protections including motor overload, over-/low-voltage, and bath overheat prevention. Plan ambient operating conditions between 5°C and 35°C.
Key Features
- Auto-inversion drive: DC brushless simple-servo motor supports forward, reverse, and automatic inversion across 5–315 rpm.
- Set inversion design: glassware and bath mount on either the left or right side to match handedness and bench layout.
- Manual spring-loaded jack: stepless flask lift to a 200 mm maximum height with one-touch locking.
- Glassware Set C: cold-finger vertical condenser engineered for volatile, low-boiling-point solvents.
- Condenser insulation kit: standard equipment that suppresses surface condensation on the condenser.
- BM302A water bath: RT +10°C to 90°C range with ±1.0°C accuracy, overheat prevention, and a 2A service outlet.
How to Choose the Right Rotary Evaporator
Selecting a rotary evaporator means matching the system to your solvents, throughput, and site power. Use these axes to confirm the RE202CWA fits your workflow .
- Capacity: the 5 L bath and 50–2000 ml flask compatibility determine batch size; size the unit to your largest routine distillation.
- Temperature range: the BM302A water bath spans RT +10°C to 90°C, suited to aqueous and low-boiling solvent recovery rather than high-boiling oil-bath work.
- Glassware type: Set C with a cold-finger vertical condenser targets volatile, low-boiling-point solvents; verify your chemistry matches the condenser style.
- Voltage: this configuration is 100–115V, 50/60 Hz, 1 A, so confirm your bench circuit before ordering.
- Footprint: the 36 × 36 × 27 in shipping envelope and 90 lb weight require adequate bench depth and access.
- Seal compatibility: FKM is standard; PTFE seals are recommended for ketone and ether solvents.
