Prevents vapor condensation in top half of flask during distillation.

• Protects flask during process
• Laced side opening
• Elliptical hole accomodates 1, 2 and 3 neck flasks

Our heated top mantle covers the upper half of a flask during distillation of high boiling materials. The tops are designed for use with our M, TM or STM mantles. They protect the flask from adverse conditions which would disturb the reflux ration during fractionation.
