Sublimation Apparatus, Vacuum, Rettberg

The vacuum sublimation apparatus made of borosilicate glass 3.3 allows you to effectively clean many chemicals and substances which, when heated, pass directly from the solid to the vapor state without first turning into a liquid and solidify again after cooling. The cleaned sublimated can be easily and completely recovered from the conical condenser at the end of the sublimation operation.
