How Does the Rotary Evaporator Work? – Extraction Magazine

Dec 18, 2018 · A rotary evaporator, or "rotovap" in lab jargon, is an instrument used in a chemistry lab to remove a volatile solvent from a liquid mixture. In a cannabis setting, the most common use for it is to remove ethanol from a winterized extract.

Rotary Evaporation to Remove Solvent | Protocol

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.

What is a Rotovap used for? - Lab Instrument Manufacturer

A rotary evaporator (Rotovap) is a piece of machinery or equipment used in the creation of some cannabis concentrates. A rotary evaporator evaporates and recovers pricey ethanol from ethanol-extracted concentrates. Rotary evaporators are one of the key steps in creating butane hash oil (BHO) and other cannabis concentrates.

AN INNOVATIVE APPROACH TO ROTARY EVAPORATOR DESIGN

the rotovap to cool the solvent distillate," says Richmond Sarpong, professor of organic chemistry at the University of California, Berkeley, who entered graduate school in 1995. Water aspirators, attached to a fast-running tap, generated the vacuum. The rotovap user would also continually run tap water through the condenser for cooling.

Any Rotovap Tips? : chemistry

the reason you spin on a rotovap is to increase the surface area exposed when evaporating, and disrupt the surface such that it doesn't bump. I rotovap at a speed fast enough to ensure the liquid in the flask is swirling, and that an even thin layer is exposed to the vacuum on each rotation. this varies based on flask size, and liquid viscosity. and in later stages how much compound I expect .
