Lower hemispherical heating mantle (HM)

Norske Backer's lower hemisphere heating mantles provide even heat distribution with low wattage for round-bottomed flasks. Made with an outer shell of fiberglass cloth and multi-stranded resistance wire, these heating mantles have increased durability and flexibility, and are an excellent alternative to a bunsen burner.

Temperature controller is required for safe operation of this product.

Temperatures up to 450 °C
Available in:
- 120 VAC includes 76 mm cord with NEMA L1-15R plug and a 1.2 m power cord
- 240 VAC includes 76 mm cord without plug.

Please note that the actual product color may vary from the images shown. Each heating jacket undergoes a finishing step that includes power supply, so that it can be heated briefly. This final step helps to reduce the amount of off-gassing (smoke caused by the fiberglass particles being heated) that is produced the first few times the heating jacket is heated. As a result, the heating jacket may be discolored when it arrives at our customers.
