Non-stirring Heating Mantles
Non-stirring heating mantles, also known as heating mantles or flask mantles, are a common laboratory alternative to hot plates, heating baths and Bunsen burners. Used to evenly heat fluids while limiting the risk of glassware shattering, heating mantles are tailored to fit specific sizes and shapes of flasks or funnels. These heating mantles do not use a magnetic stirrer and come in both single flask and multi-flask options.
In contrast to oil or water baths or other methods of applying heat to glass vessels, heating mantles generate no liquid residue that can drip off the flask.
As with electrical versions, heating mantles are helpful when the vessel needs slow or extended heating. Their flexible shape and structure (with the heating wire enclosed in a padded covering) helps distribute heat over the mantle surface for more uniform temperatures.
Most heating mantles have a soft or flexible shell that can be adapted to different glassware shapes and specific applications. They also help reduce the chances of breakage. Flexible heating mantle construction includes slip-in and zip-up options, either of which can be used with a basket ring stand.
Common heating mantle styles include:
- Spherical: For round-bottom flasks or reaction kettles
- Lower hemispherical: Half-sized; for round flasks, and where a view of the liquid is desired
- Upper hemispherical: Half-sized; for the upper part of the vessel being heated
- Cylindrical: With and without bottom drain openings for reaction vessels and kettles
- Elliptical or “mantle tops” help prevent vapor condensation on the upper part of the vessel during distillation procedures
Heating mantles require a heating mantle controller (sold separately), because they do not include temperature control mechanisms. Some controllers can be used with more than one heating mantle.

Chemglass Life Sciences 100mL Glas-Col Heating Mantle, Series O, Hemispherical, 80 Watts
100mL Glas-Col Heating Mantle, Series O, Hemispherical, 80 Watts. The Glas-Col Series O mantle is a hemispherical style, meaning it covers only the bottom half of the flask. This allows full view of contents. The mantle accommodates single and multi-flasks. It should be used with the Series O supports. All mantles are 115 Volts and are supplied with a separable 4 foot, 2 wire cord and locking connector. For Series O supports see CG-10010 or CG-10012.
Cole-Parmer HM-200-MP3-500-115 Extraction Heater, 3 Positions, 500 mL; 115 VAC
Regulating the heat on these multiposition extraction mantles is simple using the built-in solid-state electronic controls. Built for versatility, the units accept round-bottom flasks ranging from 100 to 1000 mL. Each mantle position has an independent heater, allowing liquids with different boiling points to be heated alongside each other, up to a maximum element temperature range of 450C. Each independent heater has its own control dial, on/off switch, and indicator light. If applicable, the light also indicates power supplied to stirring function. The lower part of the unit containing the control equipment is safely separated from the upper heating elements by a well-ventilated air space. A quartz heating element is housed in a thermally insulated cartridge for easy replacement, extending the life of the heater. Powder-coated aluminum surfaces and polypropylene top cover ensure good chemical resistance and easy cleanup.

Chemglass Life Sciences 500mL Glas-Col Heating Mantle, Series M, Spherical, 270 Watts
500mL Glas-Col Heating Mantle, Series M, Spherical, 270 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.
