Description
Technical Parameters
Rotovap extraction is a commonly used separation and concentration technology, which is usually used to extract or concentrate the target substance from the solution. It is based on the principle of liquid evaporation and gas condensation.
In rotary evaporation extraction, the liquid solution to be treated is placed in an evaporator and evaporated by heating. It usually have efficient evaporation surfaces, such as round bottom flasks and rotary driving devices, which can quickly increase the evaporation surface area and promote the evaporation of solutions. At the same time, through an appropriate vacuum system, the ambient pressure is reduced at a lower temperature, which makes the volatile components in the solution easy to evaporate.
With the evaporation of the solvent, the target substance is gradually concentrated and deposited on the bottom of the container. The evaporated solvent will form steam, which will be cooled by the condenser and become liquid. In this way, the solvent can be recycled, and the target substance can be separated and extracted.

Product Introduction
Rotovap extraction is a kind of material extraction method widely used in chemistry, biology, pharmacy and other fields. Its basic principle is to volatilize substances under low pressure by means of rotary heating, so as to realize rapid evaporation and concentration.
The evaporator is mainly composed of control system, heating system, rotary motor, etc., which can significantly concentrate and dry samples. In the process of extraction, it is very important to choose appropriate solvent and solution concentration, and to control evaporation speed and temperature reasonably.
Besides the basic rotary evaporation extraction equipment, there are other common extraction methods, such as centrifugal extraction, ultrasonic extraction and heating extraction. Centrifugal extraction mainly uses high-speed centrifugation to separate the solid and liquid in the sample, and then concentrates the liquid part with product. Ultrasonic extraction can not only ensure the integrity of sample components, but also has the advantages of no pollution, high speed and high efficiency. Heating extraction is to heat the sample in a product to make it volatilize the required components, which is usually suitable for the extraction of some viscous or high-boiling substances.

Product Knowledge
Step-by-step feeding rotary evaporation method in rotovap extraction is a commonly used experimental method. Its main feature is that a variety of solvents with different properties can be added to the sample step by step, so as to realize the gradual purification and concentration of the sample.
In the specific experimental operation, this method is usually realized by gradually adding different kinds of solvents into the evaporator. This method can effectively reduce the difficulty of experimental operation, improve the accuracy and reliability of the experiment.
The application range of step-by-step feeding rotary evaporation method is also very wide, which is mainly suitable for experimental operations in various fields such as chemistry, biology and pharmacy, such as separating and purifying various organic compounds and preparing high-purity drugs. Through the step-by-step feeding rotary evaporation method, different components in the sample can be separated step by step, and the required components can be purified, thus realizing efficient sample processing and preparation.
It should be noted that in the step-by-step feeding method, solvents with different properties need to be added step by step, and the amount and order of addition should be controlled to avoid affecting the experimental effect and safety. In addition, the parameters such as temperature and pressure should be controlled during the experiment to ensure the stability and safety of the experimental operation.

02
Filtration:
Using the solubility difference of substances, the impurities insoluble in water are separated from the aqueous solution, so as to realize the separation and purification of substances.
03
Sublimation method:
By using the characteristics of sublimation of some substances when heated, the sublimate is condensed and collected by controlling the conditions such as temperature and pressure, so as to realize the separation and purification of substances.
04
Extraction:
Using the difference of solubility of substances in two or more solvents, the mixture is dissolved and extracted in different solvents successively, so as to realize the separation and purification of substances.
05
Dissolution method:
Using the characteristic that some substances can be dissolved in some solvents, the substances to be purified are added to the solvent for dissolution, and then the impurities insoluble in the solvent are filtered out, so as to realize the separation and purification of substances.
06
Addition method:
The impurities are converted into the required substances, and the impurities are converted into the required substances by adding some reagents or chemical reactions, so as to realize the separation and purification of substances.
07
Absorption method:
Using the characteristics that some substances can be absorbed by specific drugs, the mixed gas can be absorbed by specific drugs, thus realizing gas separation and purification.
08
Transformation method:
It is difficult to separate the two substances directly, and it is easy to separate them by adding drugs, and then reduce them back. For example, when removing two liquid mixtures that are difficult to separate directly, a reagent can be added to convert one of the liquids into a solid or gas, so as to realize the separation and purification of the two liquids.
