Rotary Evaporator (Main Unit) Digital Overview
The Rotary Evaporator (Main Unit) Digital from Yamato Scientific (model RE202A) is a digital, manual-lift rotary evaporator built for solvent recovery and sample concentration. Evaporation capacity reaches up to 23 ml/min across a rotation speed range of 5–315 rpm. LabSupplies.com supplies this unit as an authorized Yamato Scientific dealer.
A DC brushless servo motor drives forward, reverse, and auto-inversion modes for thorough mixing. Cooling runs through a double corrugated condenser tube providing 0.143 m² of surface area. Glassware and bath mount on either side, letting technicians configure left- or right-hand operation. FKM vacuum sealing ships standard, with PTFE recommended for ketone and ether solvents.
This model runs on 100–115V, 50/60 Hz at 1 A, while the RE212A variant covers 220V sites. Manual spring-loaded lift offers 200 mm of stepless travel with one-touch locking. Net weight is roughly 10.0 kg. Manufactured in China, the unit operates in 5–35°C ambient conditions.
Key Features
- Speed control: 5–315 rpm with a digital display and control knob, plus 8 selectable brightness levels.
- Rotation modes: forward, reverse, and auto-inversion driven by a DC brushless servo motor.
- Evaporation capacity: up to 23 ml/min, with compatible evaporation flasks from 50–2000 ml and receiving flasks from 100–2000 ml.
- Manual lift: spring-loaded jack with 200 mm maximum height, stepless adjustment, and one-touch lock.
- Condenser: double corrugated tube delivering 0.143 m² of cooling surface.
- Safety functions: motor overload, over-/low-voltage and speed-sensor-error protection, plus AC adapter short-circuit, overcurrent, and overvoltage protection.
How to Choose the Right Rotary Evaporator
Selecting a rotary evaporator starts with the solvents you process and the throughput your workflow demands. Match the speed range, condenser surface, and seal material to your chemistry .
- Evaporation capacity: up to 23 ml/min here suits routine concentration; verify it meets your batch volume needs.
- Flask compatibility: support for 50–2000 ml evaporation flasks and 100–2000 ml receiving flasks determines run size.
- Control type: a digital display with rotation modes (forward, reverse, auto-inversion) improves repeatability over basic analog units.
- Seal material: FKM is standard, but PTFE is recommended for ketone and ether solvents — confirm your solvent list.
- Voltage: choose RE202A for 115V sites or RE212A for 220V sites to match your bench power.
- Footprint and weight: at roughly 10.0 kg with a 200 mm manual lift, plan bench clearance and condenser access.

Frequently Asked Questions
What ambient temperature range does the RE202A operate in?
The RE202A operates in a 5–35°C ambient temperature range. Keep the unit within these conditions for stable performance during solvent recovery and concentration.
What is the evaporation capacity and rotation speed range?
Evaporation capacity reaches up to 23 ml/min. Rotation speed is adjustable from 5 to 315 rpm using the digital display and control knob, with forward, reverse, and auto-inversion modes.
What flask sizes are compatible with this rotary evaporator?
Compatible evaporation flasks range from 50 to 2000 ml, and receiving flasks from 100 to 2000 ml. An optional reducer accommodates smaller evaporation flasks.
Does the RE202A run on a standard 115V circuit?
Yes. The RE202A runs on 100–115V, 50/60 Hz at 1 A and ships with a plug. For 220V sites, select the RE212A variant instead.
What seal material is used, and is it suitable for ether solvents?
FKM vacuum sealing is standard. For ketone or ether solvents, Yamato recommends a PTFE seal to maintain vacuum integrity and chemical resistance.
What is the difference between the RE202A and RE212A?
The only difference is supply voltage. The RE202A is the 115V model and the RE212A is the 220V model; both share the same specifications, capacity, and features.
