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

Principle of molecular distillation: molecular distillation, also known as short-range distillation, is a liquid-liquid separation technology under high vacuum (10-1 ~ 101pa) It has the characteristics of low distillation temperature, high vacuum degree, short heating time and high separation degree, and the separation process is irreversible without boiling and bubbling It is especially suitable for the separation of substances with high boiling point, heat sensitivity and easy to be oxidized Composition of molecular distillation equipment: a complete set of molecular distillation equipment mainly includes feed system, molecular distiller, heating system, cooling system, vacuum system and control system In order to ensure the vacuum degree, the two-stage pump is generally used in combination, and a liquid nitrogen cold trap is set to protect the vacuum pump The soul of the vacuum system of the circulating water vacuum pump the circulating water vacuum pump produced by our company can provide the vacuum environment for the molecular distillation experiment It is an important part of molecular distillation equipment The product can recycle water, save water resources, solve the shortage of water resources in some places, and be resistant to acid, alkali and solvent corrosion Cooling system the cooling system of molecular distillation equipment refers to the equipment that can provide cooling environment for molecular distillation equipment, such as dl-400, dlsb series low temperature coolant circulating pump The lower the temperature, the smaller the cooling capacity When you choose refrigeration products, please select the product model matching the temperature range and refrigeration capacity according to the required temperature range and experimental heat, so as to achieve the best experimental effect of Zui.
