The Glas-Col® Series STM mantle performs the same function as a Series TM heating mantle, plus operations requiring more heat.

• The STM mantle has a durable aluminum exterior and a resilient and pliable interior to cradle glassware
• Withstanding an upper internal operating temperature of 650º C, the STM mantle is very resistant to burnout
• A splash guard and poncho safety shield can be used to prevent damage from accidental spills

The higher temperature range enables operations to be performed that require more heat, such as rapid distillation of water and liquid-phase cracking in a flask, where the products are taken out of the flask through a column. Useful in distillation and fractionation processes, especially when time is important.
