The difference between several distillation equipment

The commonly used distillation equipments include rotary evaporators, falling film evaporators, molecular distillation, and wiped film molecular distillation equipment.The main differences are:

1.Rotary evaporator: the lower the pressure, the lower the boiling point. It is best that the boiling point difference between the two substances is large, the boiling point is similar, and it is not easy to separate. The decompression can lower the boiling point and use less heat.

2.Falling film evaporator:Strong evaporation capacity, energy saving, low operating cost,It is widely used in the evaporation and concentration of water or organic solvent solutions in the pharmaceutical, food, chemical, light industry and other industries, and can be widely used in the waste liquid treatment of the above industries, especially for heat sensitive materials.The device can be operated continuously under vacuum and low temperature conditions;

3.Molecular distillation:
Suitable for substances with a high boiling point,Very efficient, compared to a rotary evaporator, a short heating time, a distillation method operating under high vacuum, separating the liquid mixture;

4.Wiped film molecular distillation:
More efficient than rotary evaporators, separating volatile and non-volatile materials, and the process is very gentle; performance is significantly better than flash equipment, falling film distiller, rotary evaporator and other devices.
