Rotary Evaporator

RV-B Series

The RV-B Series Rotary Evaporator employs stepless speed regulation to keep the glass rotary flask rotating at a constant speed. The material forms a large-area uniform thin film on the flask wall and is then evenly heated by an intelligent constant-temperature water bath. Under vacuum conditions, rapid evaporation occurs. The solvent vapor is condensed by a high-efficiency glass condenser and collected in a receiving flask. The rotary evaporator operates under vacuum, and all parts in contact with the material are made of high-temperature-resistant borosilicate glass and polytetrafluoroethylene (PTFE). It is particularly suitable for concentrating and purifying biological products that are prone to decomposition and denaturation at high temperatures.

Features

Main bracket made of anti-corrosion spray-coated aluminum alloy, with rational structure and high-quality materials.

Sealing system uses a combination of PTFE and imported fluororubber seals, maintaining a high vacuum.

All glass components are made of high-borosilicate glass (GG-17), resistant to high temperatures and corrosion.

Continuous feeding is possible for user convenience with a valve-type feeding tube with PTFE tubing;

A vertical double-layer serpentine coil condenser ensures a high recovery rate, with an additional feeding tube.

Water bath with digital display and intelligent constant-temperature control; Cu50 sensor provides fast and accurate temperature transmission.
