The MTST RE-201D is a rotary evaporator built for solvent recovery and distillation tasks. It pairs a 2 L evaporating flask with a 1 L receiving flask and a 1200 W heated water/oil bath, giving operators control over evaporation conditions across a wide temperature range.

The unit uses high borosilicate glassware and PTFE with fluoro-rubber sealing to handle reduced-pressure operation. Stepless rotation speed and a motorized lifting mechanism support repeatable, hands-on process control.

It is intended for extraction and processing labs that need to recover solvent from crude extract or concentrate dissolved material under vacuum.

How It Works

A motor rotates the evaporating flask while it is partially submerged in the heated bath. Reduced pressure from a vacuum source lowers the solvent boiling point, and vapor is drawn to a condenser cooled by a recirculating chiller, where it condenses and collects in the receiving flask.

Key Features

• 2 L evaporating flask and 1 L receiving flask in high borosilicate glass
• 1200 W heated bath with a temperature range of RT to 399°C and ±1°C accuracy
• Stepless rotation from 0 to 120 rpm driven by a 40 W motor
• Motorized lifting over a 0–150 mm range
• PTFE and fluoro-rubber sealing for vacuum operation down to <133 Pa (1 Torr)
• Bath chamber sized Φ24 × 15 cm
• Optional evaporation rate of at least 1 L/h (H2O)

Applications

• Recovering solvent from cannabis crude extract under vacuum
• Concentrating dissolved samples in extraction workflows
