Rotary Evaporators for Extraction

Rotary evaporators for extraction

It’s commonly known that the extraction refers to a process in which one or more components are extracted or separated from a mixture. There are a great variety of extraction equipment, such as closed loop extractor, falling film evaporator, rotary evaporator, wiped film evaporator and so on. All these extraction equipment can be used to extract or separate components from a mixture efficiently, but their structures vary from each other. The rotary evaporator is one of the most essential and efficient extraction equipment widely used in many fields, including chemical, biochemical, industrial fields and even at home.

The extraction function of rotary evaporators is used in many fields. In industrial field, people use rotary evaporators to extract cbd, which is the main component of mariguana. And cbd is usually used to be made into medicine in pharmaceutical field. In people’s daily life, rotary evaporators are used at home for extracting water from all kinds of juices, which makes juices have a better taste. In chemical and biochemical labs, rotary evaporators are used by professors to extract chemical substances, which will be further applied for other chemical purposes. What’s more, essential oil extraction should be completed by rotary evaporators. All in all, the extraction is the most important function of rotary evaporators.

Rotary evaporators for essential oil extraction

Besides the use in chemical, biochemical and industrial fields, even at home, rotary evaporators can be used for essential oil extraction as well. The working principle of rotary evaporators for essential oil extraction is : under the action of vacuum and rotation, the rotary evaporator extracts essential oil by subjecting the mixture to heat and removes the volatile components fast. Then the left part will be collected and made into the essential oil.

What is the principle of rotary evaporators?

The principle is that the boiling points of liquids can reduce with the decreasing pressure. As a result, the solvents are capable of being vaporized at much lower temperature than their boiling points at the normal pressure.
