The role that cold trap plays in rotary evaporator equipment

The function of cold trap A cold trap is a device that prevents vapor or liquid from entering the measuring instrument from the system or from the measuring instrument into the system. Generally, the cold trap is used to prevent oil vapor from returning to the application equipment in the vacuum environment, which can cause […]

Why rotary evaporator distillation is more widely used

Why rotary evaporator distillation is more widely used Rotary evaporator becomes more and more popular since it was invented. Because it dose have several advantages better than other distillation equipment, the contrast is as follows: Speed -the rotary evaporator distillation is faster. The rotary evaporator is electronically controlled to rotate the flask at a constant speed, […]

Rotary evaporator for extraction

Rotary evaporator for extraction There are all kinds of extraction equipment in many fields, for example, closed loop extractor, falling film evaporator, rotary evaporator, wiped film evaporator and so on. All these extraction equipment are to extract substances from mixtures efficiently, but their structures are different. Rotary evaporator is one of the most efficient extraction equipment, […]

Rotary evaporator extraction method

Rotary evaporator extraction method Rotary evaporator extracts and concentrates substances from mixtures by heating and evaporating sample materials according to the different boiling points of substances within mixtures. The basic principle of a rotary evaporator is the vacuum distillation of the distillation flask under continuous rotation. Many people still wonder the very specific details of rotary […]

The boiling points of rotary evaporator ’s extracted substances

Rotary evaporator is famous for its wide uses in many fields. It can be applied for the extraction and concentration of substances in chemical labs, people’s daily life at kitchen to concentrate juices or food, make up and perfume, industrial uses and other uses. Rotary evaporator is very resource-saving and has a very high efficiency. […]

Rotary evaporator vs short path distillation

Rotary evaporator and short path distillation are both the equipment to extract or concentrate substances, which are widely used in many fields and high-efficiency. Rotary evaporator and short path distillation have the same function, but rotary evaporator can only process one single material while short path distillation can process two or three materials. Besides that, […]

Food made by rotary evaporator

Food made by rotary evaporator Rotary evaporator is widely used in many fields, including chemical field, biochemical field, make up and perfume field, industrial field and other fields. Besides, rotary evaporator is used in people’s daily life at home for cooking. Therefore, rotary evaporator has been used beyond industrial and chemical field for a long […]

Why do people choose to extract cbd by rotary evaporator 

Rotary evaporator extracts cbd through extraction method. Because the main methods used to extract active ingredients (usually organic compounds) from plants include steam distillation, pressing and extraction. The distillation method is suitable for substances with high volatility, and the pressing method is suitable for the extraction of eschar materials which are liquid at normal temperature. […]

Rotary evaporator disadvantages

Rotary evaporator is mainly used for concentration, crystallization, drying, separation and coal recovery in the pharmaceutical, chemical and biopharmaceutical industries. The principle is as follows: the rotating bottle rotates at a constant speed under vacuum condition and heating condition at a constant temperature, and the material forms a large-area film on the bottle wall and evaporates efficiently. The […]

How does a rotary evaporator remove solvent

How does a rotary evaporator remove solvent The rotary evaporator is mainly used to continuously distill a large amount of volatile solvents under reduced pressure, such as extraction by distillate and a receiving liquid for chromatographic separation.The basic principle of a rotary evaporator is to evaporate sample materials with evaporation flask’s continuous rotation. The process is as follows: Turn […]
