High Borosilicate Vacuum Short Path Distillation for Lab 5L

Short Path Distillation Equipment Description

The short path distillation refers to a kind of evaporation and distillation equipment. As a type of thermodynamic separation technology, the equipment can evaporate components with low boiling points by utilizing that the boiling point of each component in the mixed liquid or liquid-solid mixture is different, and then condense the material to separate the whole components. 

Short Path Distillation Equipment Principle

The material should add from the top of evaporator and continuously spread to the heating surface through the material covered on rotor. Then, the scratch film is capable of scratching the material into a thin and flowing liquid film. During this process, the light molecular exceeded the heating surface form the condense liquid on inside condenser without any collision. Then, the molecular flows along the condenser tube, and discharge through the discharge tube on the bottom of evaporator. The residue liquid (heavy molecule) is collected on the circular channel under the heating zone, and flows through the discharge tube on one side.

Short Path Distillation Equipment Structure

The column cylinder is equipped with outside heating mantle, rotor and inside condenser. The fixing frame of rotor is precisely equipped with scratch film and anti-splash device. The inside condenser is placed in the center of evaporator, and the rotor should rotor between column cylinder and condenser.
