Application of circulating water vacuum pump and low temperature coolant circulating pump in molecular distillation experiment

The principle of molecular distillation:

Molecular distillation, also known as short-path distillation, is a liquid-liquid separation technique carried out under high vacuum (10-1~101Pa). The utility model has the advantages of low distillation temperature, high vacuum degree of the system, short heating time of the material, high degree of separation, and the like, and the separation process is irreversible, and there is no boiling bubbling phenomenon. It is especially suitable for separating high boiling point, heat sensitive and easily oxidizable substances.

The composition of the molecular distillation equipment:

A complete molecular distillation unit consists mainly of feed systems, molecular distillers, heating systems, cooling systems, vacuum systems and control systems. In order to ensure the degree of vacuum, a two-stage pump is generally used in combination, and a liquid nitrogen cold trap is used to protect the vacuum pump.

Circulating water pump vacuum system of soul <br> <br> I produced the circulating water pump distillation experiments can provide a vacuum environment for the molecule. It is an important part of molecular distillation equipment. This product recycles water, saves water resources, solves the problem of insufficient water resources in some places, and is resistant to acid, alkali and solvent corrosion.

For the cooling system <br> <br> molecular distillation apparatus refers to an apparatus for cooling environment to provide molecular distillation equipment, such as: DL-400, DLSB series cryogenic coolant circulation pump. The lower the temperature, the smaller the cooling capacity. When you choose a cooling product, please select the product model with the matching temperature range and cooling capacity according to the required temperature range and experimental heat generation.
