Rotary evaporation is the process of reducing the volume of a solvent by distributing it as a thin film across the interior of a vessel at elevated temperature and reduced pressure. This promotes the rapid removal of excess solvent from less volatile samples. Most rotary evaporators have four major components: heat bath, rotor, condenser, and ... 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.

2020 Latest Rotary Evaporator – Buying Guide

Remember, when the condenser on your evaporator is 20 degrees Celsius cooler than your sample, it will condense most of the vapors leaving the evaporator. That means that a small pump with modest pumping capacity – 1 cfm or less – will provide enough pumping to manage the residual vapors that reach the pump from most benchtop evaporators. The rotary evaporator R-100 is a high-quality, entry level Rotavapor to meet the essential needs in classical laboratory applications. It is capable of a manually adjustable rotation speed of 20 to 280 rpm and equipped with an action jack lift for manual lifting of the evaporating flask. Included is…

Standard Operating Procedure - Rotary Evaporator

Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.  · A vacuum pump lowers a solvents boiling point by reducing pressure within the rotary evaporator. The water bath is deployed at 30-40 degrees with an ethanol vapor temperature 15-20 degrees C. Lower water bath temperatures prevent thermal decomposition.
