Vacuum Regulator For Re-202-A/212-A Overview
The Vacuum Regulator VR102S is a dedicated vacuum controller for Yamato Scientific rotary evaporators, engineered to hold precise pressure across a 0–1013 hPa setting range. LabSupplies.com, authorized dealer, supplies this unit for labs running distillation, solvent recovery, and concentration workflows on the RE202A and RE212A platforms.
A 2.3-inch color LCD anchors the interface, displaying pressure in five selectable units: mmHg, Torr, hPa, kPa, and mbar. Three operation modes — Manual, Gradient, and Auto — let technicians match control behavior to the solvent and the run. Auto-leak and auto-cleaning routines execute at the end of each operation.
Powered by 24V DC from a 100–240 VAC input drawing 1 A or less, the VR102S adapts to standard lab mains and weighs just 0.5 kg. Manufactured in China, it integrates with RE202A, RE212A, REV202MA, and REV212MA evaporator systems.
Key Features
- Wide vacuum control: 0–1013 hPa setting range with 0–1100 hPa measurement coverage.
- 2.3-inch color LCD: readable pressure display with selectable mmHg, Torr, hPa, kPa, and mbar units.
- Three operation modes: Manual, Gradient, and Auto control for solvent-specific runs.
- End-of-run automation: auto-leak and auto-cleaning functions execute automatically at operation end.
- Multi-layer safety: communication, pressure-sensor, memory, leak, and high-pressure error detection with auto-leak on fault.
- Model compatibility: integrates with RE202A, RE212A, REV202MA, and REV212MA evaporators.
How to Choose the Right Rotary Evaporator
Selecting a rotary evaporator setup means matching the vacuum control, evaporation flask, and power source to your solvents and throughput. A dedicated vacuum regulator like the VR102S sharpens reproducibility on the units it supports. Weigh these axes before specifying.
- Vacuum control type: Manual, Gradient, and Auto modes determine how tightly you can track boiling points across mixed-solvent runs.
- Vacuum range: confirm the setting range (0–1013 hPa here) covers the pressures your solvents demand.
- Model compatibility: verify the regulator matches your evaporator family — this unit fits RE202A, RE212A, REV202MA, and REV212MA only.
- Power supply: a 100–240 VAC input simplifies deployment across regions and standard lab circuits.
- Safety functions: leak, high-pressure, and sensor error detection protect samples and equipment during unattended runs.
- Display and units: a color LCD with multiple pressure units speeds setup and reduces conversion errors.

Frequently Asked Questions
Which rotary evaporators is the VR102S compatible with?
The VR102S is compatible with Yamato Scientific RE202A, RE212A, REV202MA, and REV212MA rotary evaporators. It is a dedicated vacuum regulator for these models and is not a universal controller.
What vacuum range does the VR102S control?
The VR102S controls vacuum across a 0–1013 hPa setting range and measures pressure from 0 to 1100 hPa. Pressure can be displayed in mmHg, Torr, hPa, kPa, or mbar.
What power supply does the VR102S require?
The VR102S operates on 24V DC supplied from a 100–240 VAC input drawing 1 A or less. This wide-input range supports standard lab mains across regions.
What control modes does the VR102S offer?
The VR102S provides three operation modes: Manual, Gradient, and Auto. These let technicians match vacuum behavior to specific solvents and run requirements.
What safety features are built into the VR102S?
The VR102S includes communication, pressure-sensor, memory, leak, and high-pressure error detection, plus an auto-leak function on fault. It also runs auto-leak and auto-cleaning at the end of each operation.
How much does the VR102S weigh and where is it made?
The VR102S has a net weight of 0.5 kg and is manufactured in China. Its compact size suits integration alongside RE202A and RE212A evaporator setups.
