Insulate and help prevent vapor condensation.

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

This mantle does not heat but insulates and helps prevent vapor condensation in the upper half of a flask during distillation of high boiling materials. Our insulating tops are Series M, TM, or STM heating mantles. They protect the flask, the solutions and the laboratory.
