Rotary evaporator has a key role in the pre-treatment purification of Chinese herbal medicine
The rotary evaporator is a device that uses a rotary evaporation bottle (flask). The evaporation area is placed in a water bath under reduced pressure while rotating and heating. The principle is: under vacuum conditions, constant temperature heating makes the rotating bottle rotate at a constant speed, and the material A large area film is formed on the bottle wall for evaporation. The dissolved coal vapor is cooled by the glass condenser and recovered in the collection bottle, which greatly improves the evaporation efficiency. It is especially selected for the concentration and purification of biological products that are easily decomposed and denatured at high temperatures. Rotary evaporators are widely used in scientific research and production processes in pharmaceutical, chemical, biological products and other industries. They are indispensable equipment in evaporation, concentration, crystallization, drying, separation, solvent recovery and other processes. Among them, the concentration of traditional Chinese medicine extract is a typical application of the rotary evaporator. The rotary evaporator uses a heating tank to heat and evaporate the solution, and removes part of the extractant through the condensed steam in the condenser tube, thereby increasing the solute concentration in the solution.

About cryostat reaction bath, do you know how it works?
The low-temperature constant temperature reaction bath is also called a low-temperature constant temperature tank, a low-temperature constant temperature water tank, a low-temperature bath, a low-temperature reaction bath, a low-temperature tank, a cold trap, a low-temperature constant temperature reaction tank, a low-temperature constant temperature reaction bath, etc. The structure is rectangular, and the outer shell is made of cold-rolled steel plates with good performance. The physical properties of the refrigeration device adopt foreign advanced fluorine-free refrigeration technology, coupled with a microcomputer intelligent temperature control system, which can control temperature changes with high precision to achieve a constant temperature. Low-temperature constant temperature reaction baths are widely used in petroleum, chemical industry, electronic instrumentation, physics, chemistry, bioengineering, medicine and health, life sciences, light industrial food, physical property testing and chemical analysis and other research departments, colleges and universities, enterprise quality inspection and production departments . Provide users with a liquid environment with controlled heat and cold, uniform and constant temperature when working.

As the name suggests, the double-layer glass reactor adopts a double-layer glass design. The interlayer of the glass can be connected to a high-temperature or low-temperature source to provide experimental temperature for the experimental materials inside the kettle. The advantage of this design is that the experimental materials can not be collected to pollution. The double-layer glass reactor has good sealing performance as a whole and can be used for vacuuming operations, so as to achieve the best experimental results under reduced pressure and conduct vacuum experiments. Double-layer glass reactors have been reused in petroleum, chemicals, pesticides, medicine, food and other industries due to their excellent performance. It is a common choice for completing vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation and other processes. However, the reaction materials also need to be considered in the design of the double-layer glass reactor. Under normal circumstances, the requirements for the reaction materials are as follows:

Double-layer glass reactor manufacturers distillation principle analysis
Distillation uses the difference in volatility of the components in a mixed liquid to partially evaporate the mixed liquid, and then partially condenses the vapor to separate the contained components. It is a unit operation of mass transfer separation and can be used in oil refining, chemical industry, light industry and other industries.
