As the pressure is reduced using a vacuum pump in the rotary evaporator, the boiling point of the solvent, ethanol in this case, is lowered. Typically, the distilling flask (A) is filled to 50% volume. The water bath (B) is heated to 30-40°C. The condenser temperature (F), controlled by a recirculating chiller, is set to .
A sample from the THF bottle was later analyzed with a simple test and found to contain excessive peroxides (more than 100 mg/l). The evaporation in the rotovap concentrated the peroxides in the bottom of the glass reaction vessel and any movement of the vessel could cause the now dry and shock sensitive peroxides crystals to explode.

A rotovap typically uses a cold condenser to condense the solvent into a collection flask. But the distillation is typically done under weak vacuum as well. So the solvent sitting in the collection flask seem susceptible to re-vaporizing and getting sucked into the vacuum pump. Now I have a cold trap in front of my pump that should be cold .

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.

Apr 24, 2020 · A chemical reactor refers to the process vessels use to perform a chemical reaction. Reactors usually vary in size and, thus, are never the same. An example of this is the kiln that is used to produce lime from limestone, which may be 25 metres high and can hold materials above 400 tonnes.
