"Batch" distillation with padding

DESCRIPTION

Permits the separation of the components of a liquid mixture because of differences in boiling points. The mixture is heated vaporizing some of the components and leaving a residue behind. The vapours are then condensed and collected.

Material used tolerates corrosive substances.

This unit is made for batch rectification at atmospheric pressure or reduced pressure.

A user manual and technical documentation are provided.
