The condenser temperature (F), controlled by a recirculating chiller, is set to -10°C to 0°C. Once the water bath and condenser have reached the set points, the distillation flask is rotated from 150-200 rpm. This creates a thin film on the upper surface of the glass cylinder, which increases the solution surface area and enhances the solvent .
Oct 01, 2009 · Rotary Evaporator is used to remove high boiling solvents under low pressure. Here is a demonstration on how to use rotary evaporator in CHEM 2050 Labs.
During this process, suitable vacuum system is very important. When use rotary evaporator in cbd oil extraction process, ethanol is the common solvent in cbd extracts, in order to achieve a better target, we could set the vacuum to achieve an ethanol vapor temperature of 15-20℃.

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.

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 .
Adapters permit the connection of standard laboratory dram vials directly to the vapor tube or bump trap of a rotary evaporator.Adapters have joints with tube connections in various configurations to fit any reaction system. These bent or straight adapters are fabricated from borosilicate glass to provide a leak-proof fit with other glass instruments.
Use these evaporating flasks with any rotary evaporator. Buchi™ Evaporating Flasks offer high chemical resistance against acids, alkalis and organic substances. Ideal for the distillation of solvents.
This product contains a complete setup for the rotovap: 1L evaporation flask with keck clip, 1L receiving flask with metal clamp, a vertical condenser with coil, a 5L heated bath unit, and a set of hose connectors. The motor creates a very smooth rotation, and the bath maintains a stable temperature. Both the RPM and temperature displays are .
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.

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 .

Rotary evaporator is better to use when you want to get rid from the solvent. Let's say you have a solution of some chemical in some solvent. If you want to obtain a crystal form of the chemical, you may put solution to rotary evaporator and evapo.
Connect chiller to the condenser and set to 0C (32F). Always fill a rotovap condenser from the top down (chiller output to top of the condenser, chiller input to bottom of the condenser). Connect vacuum pump to cold trap and connect cold trap to the vacuum port on rotovap. Turn on heat bath and set to 40C (113F).
