22000mL Glas-Col Heating Mantle, Series M, Spherical, 2 @ 770 Watts. The Glas-Col Series M mantle is the most compact mantle with an aluminum shell that can heat flasks up to 72 liters. Like the series TM, this mantle has a durable aluminum housing outside and resilient glass fabric inside to support flasks and protect flask walls from thermal strain. The internal operating temperature is 450 C. Only the bottom of the flask is covered so the contents being heated are fully visible. The mantle is grounded through the aluminum housing and requires a support such as CG-11004 through CG-11008. All mantles are 115 Volt and are supplied with a detachable 4 foot, 3 wire cord.
