Continuous distillation

DESCRIPTION

Permits the separation of the components of a liquid mixture due to differences in their boiling points. The liquid is heated to produce a vapour leaving behind a residue. The vapour is condensed before it is collected.

The material used can tolerate corrosive substances.

This unit can be used for batch or continuous distillation. It can operate at atmospheric pressure or under reduced pressure.

A user manual and technical documentation are provided.

Option : computerized control
