Laboratory Round Bottom Flask Heating

Laboratory Round Bottom Flask Heating

A safe and efficient way to heat liquids in round-bottom flasks


HM Housed Mantle - Lab mantle

Many applications in chemistry, biology, and research laboratories involve heating liquids for research experimentation. Glass round bottom flasks are commonly used for distilling, chemical reactions, and refluxing techniques. Round bottom flasks are desirable for these operations because they have a spherical base that allows more surface area to be heated than a standard flat bottom flask. Because of the round bottom design, careful consideration must be made to stabilize the flask and keep the flask upright and safe during use.

Open flame heating can create uneven hotspots and less desirable heating performance. It can also introduce many significant safety hazards in a lab environment. Having a safe easy-to-use heater increases productivity and reliability.

Explanation of common laboratory heating techniques:

  • Distillation – Separating a component or substance from a liquid mixture by selective evaporation and condensation.
  • Chemical Reaction – A process during which one or more substances (the reactants) are converted to one or more substances (the products).
  • Refluxing – Used to supply energy to heated reactions over long periods of time, refluxing involves the condensation of vapors and the return of this condensate back into the system where it originated.


BriskHeat’s HM series metal-housed mantles are specifically designed to heat roundbottom flasks. Sizes are available ranging from 50ml to 6,000ml. The flask rests within the spherically shaped knitted fiberglass heating basket to provide stability and safety. The basket’s spherical design also allows for premium surface contact to be made around the lower-half of the flask for an even distribution of heat. The hightemperature heating capability up to 450°C (842°F) provides the versatility needed to perform a wide variety of experimentation processes. For added convenience, the mantles are available with or without a built-in temperature controller.

An accessory clamp can be mounted to the heating mantle’s housing to accommodate a frame rod used for connecting clamps, rings, etc. to the apparatus.

Additional Features:

  • Premium plastic-coated metal housing
  • Chemical resistant
  • Thermally insulated for a safe-to-touch heater
  • Grounded for enhanced electrical safety
  • Built-in 1 or 2 zone heating capability for added versatility
  • Available with or without a built-in temperature controller
