Upper hemisphere heat mantles (HM)

Norske Backer's upper hemisphere heating mantles provide uniform and low-power heat distribution to laboratory flasks, specifically developed for round-bottomed glass flasks. With an outer sheath of fiberglass fabric and stranded resistance wire, these heating mantles offer high flexibility, durability and safety - an excellent alternative to Bunsen burners. Although designed for glass flasks, they can also be used with metal or plastic flasks, as long as proper temperature control and product selection are used.

Note: Temperature controls are necessary for safe use.
