Rotary Evaporators
A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporation is most often and conveniently applied to separate “low boiling” solvents such a n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure. However, careful application also allows removal of a solvent from a sample containing a liquid compound if there is minimal co-evaporation (azeotropic behavior), and a sufficient difference in boiling points at the chosen temperature and reduced pressure.

The new SolventVap 5L to 50L series rotary evaporators are now ETL tested to UL/CSA standards (optional). This certification is required by many municipalities, and it also provides a higher standard of equipment safety and lifespan. All SolventVap come with all PTFE valves for solvent-resistant operations. Also come standard are vertical glassware and digital temperature/rotation controllers. Their optimized bath volume allows for rapid heat-up times. The condenser units are specially designed glass tubes that utilize surface area extremely efficiently. That’s why our SolventVap evaporators consistently deliver reliable and reproducible process results that are usually reserved for more costly systems.

Another important aspect of the SolventVap is the safety features, which includes dry-run protection, water bath over-temperature shut-off protection, and fuse protection.
