CBD rotary evaporator cannabis distillation equipment


Our rotary evaporators are divided into large rotary evaporators, laboratory rotary evaporators and small rotary evaporators. They are very versatile. The extraction method of the rotary evaporator is very suitable for extracting CBD.

CBD rotary evaporator


What is a rotary evaporator?

Rotary evaporator, also called rotovap, is a commonly used equipment in laboratories. It consists of a motor, distillation flask, heating pot, condenser, etc. It is mainly used for continuous distillation of volatile solvents under reduced pressure, and is used in chemistry and chemical engineering. , Biomedicine and other fields.

The rotary evaporator can be used to recover and evaporate organic solvents. It uses a motor to drive the distillation flask to rotate. Since the distiller is constantly rotating, the zeolite can be eliminated without bumping. At the same time, due to continuous rotation, the liquid is attached to the wall of the distiller to form a layer of liquid film, which enlarges the evaporation area and accelerates the evaporation speed.

What is CBD?

CBD is an extract of medical hemp. Hemp has more than one hundred kinds of active ingredients, and CBD is one of the most medically valuable. Its advantages are: nerve protection, skin inflammation improvement, antioxidant effect, and soothing skin sensitivity and redness , Establish a protective barrier for the surface of the skin, improve the self-repairing ability of the skin, etc.; it is very helpful to restore skin health and relieve skin problems. CBD is non-toxic in non-transformed cells, does not induce changes in food intake, does not induce systemic stiffness, does not affect physiological parameters (heart rate, blood pressure and body temperature), does not affect gastrointestinal transport and does not change the spirit Sports or mental function. In recent years, low-concentration CBD has appeared in health care products, foods and skin care products.

How to use a rotary evaporator in cannabis extraction?

Step 1: Adjust the height of the rotary evaporator. The rotary evaporator can be raised or lowered manually. When in use, the knob should be controlled: if you turn the knob, the rotary evaporator will rise; if you turn it in the opposite direction, the evaporator will drop. The rotary evaporator can be raised or lowered electrically. If you press the up button, the main unit will go up; if you press the down button, the main unit will go down.

The second part: There are two external ports on the condenser, these two external ports are used to connect the condensate water. One external interface is used for water inflow, and the other external interface is used for water outflow. However, it should be noted that the lower the temperature of the condensed water, the better the condensation effect. At the same time, the upper interface also has a vacuum connection device to maintain the vacuum state.

Step 3: Before restarting the rotary evaporator, please turn the knob to the minimum value, then press the power button, and turn on the switch light. Next, slowly turn the switch on the right side to adjust to the desired temperature. Generally speaking, the larger evaporating flask rotation speed is kept at a medium-low speed, and the liquid solvent with a higher viscosity is kept at a higher rotation speed. The standard interface model of the flask is No. 24, and there are two types of bottling, 500ml and 1000ml. You can choose according to your needs during use. Under normal circumstances, the volume of the solution should not exceed 50%.

Step 4: When using a rotary evaporator, you need to release its pressure first, and then turn on its motor and evaporation flask. When the trial is over, the motor should be stopped first to prevent the distillation flask from falling off during the rotation.
