Instrument Introduction

The rotary evaporator is a kind of concentration, crystallization, drying, separation and refining instrument. The rotary flask rotates at a constant speed under vacuum conditions and constant temperature, allowing the material to form a film on the wall of the flask and evaporate efficiently. The solvent vapor is then cooled through an effective condenser and collected with a receiving flask, which is especially suitable for the concentration and purification of biological products that decompose easily at high temperatures. It is mainly used in the pharmaceutical, chemical and bio-pharmaceutical industries.

Instrument Features

¦ Advanced PTFE components sealing system, maintain high vacuum degree; Gas-liquid separation, without reflux.

¦ PTFE sealing on all connection ends, resistant to difference solvents

¦ Evaporating Flask connected by nylon nut, easily install and disassemble

¦ Evaporating Flask with wide side opening, easy for operate and clean (RE-1002, RE-2002, and RE-5003)

¦ Equipped with vacuum meter, adjust best working vacuum degree for low boiling point solvent

¦ Double condensation system ensure high receiving rate. (RE-1002, RE-2002, and RE-5003)

¦ Frequency conversion speed control, digital display, convenient and intuitive operation

¦ Electric or manual lifting bath pot, with PID intelligent temperature controller, temperature digital display with high accuracy

¦ Continue solvent discharging and feeding during evaporation process, no need to stop to re-pump the vacuum system, ensure excellent constant vacuum performance

¦ Modular design, strong scalability; standard connection, convenient for changing
