The studies have shown that cannabisdiol (cbd) has a important medicinal value and good pharmacological function in the fields of epilepsy treatment, neuroprotection, multiple sclerosis, rheumatoid arthritis, tumor treatment and so on . Besides being used in medical field, cbd is also widely used in other fields, for example, textile, cooking, leather, essential oils, construction and so on. So how to extract cbd efficiently is very important. Extracting cbd by rotary evaporator extraction method is very popular in rotary evaporator laboratory, because rotary evaporator has a very high efficiency on extracting or concentrate substances. The rotary evaporator parts will work together to reach a high efficiency to extract cbd. So how to use rotary evaporator extract cbd from hemp correctly is very essential.
then let’s go through the operating procedure together:
1.Open the condensing part of rotary evaporator
2.Open water bath and adjust the heating temperature up to the boiling point of cbd
3.Open the vacuum pump and make circulating water within vacuum pump flow
4.Closing the button of gas outlet
5.Install the evaporation flask and adjust the height of water bath. After that, evaporation flask will rotate in a consistent continuous speed. The hemp within evaporation flask will be heated and cbd substance will get evaporated. Then the
gas-phase cbd will be transferred into condensing part to be condensed into liquid. Finally, the liquid-phase cbd will go to collecting flask and be collected in there for users convenient to get.
6.When you finish the evaporating operation, close the evaporating button, open the button of gas outlet, make the water bath down and remove evaporation flask.
7.Last but not least, you need to turn off water bath power, condensing part and vacuum pump.
The whole operating process happens under vacuum. If you have rotary evaporator questions during the process, you can look up in the rotary evaporator manual.
