"Batch" distillation demonstration

DESCRIPTION

Permits the separation of the components of a liquid mixture due to a difference in boiling points for the components of the mixture. The operation is based on the vaporization of a liquid leaving behind part of the mixture as a residue. The resulting vapour is then collected after it has been condensed.

This unit allows for an excellent demonstration of distillation.

The unit is easily moved into position.

A user manual is provided.
