Upper Hemisphere Heating Mantles

Prevent Vapor Condensation in the Upper Half of Flasks!

Upper hemisphere heating mantles are laboratory heaters designed to wrap around the upper half of glass flasks to prevent vapor condensation. The opening of our upper hemisphere heating mantles can accommodate 1, 2 or 3 neck flasks on a ring stand. These heaters feature a fiberglass cloth outer shell and multi-stranded resistance wire for increased durability and flexibility. We carry heating mantles in a range of size and voltage options. These heating mantles require a temperature controller for safe operation, not included.
