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.

Cole-Parmer EH-200-6-L 6-Well Macro-Kjeldahl Extraction Heater, 800 mL, UK; 230 VAC
These multiposition extraction heaters let you run several projects simultaneously by using either two or six individually controlled heating mantles. Each mantle has an independent heater with control dial, on/off switch, and indicator light, and operates to a maximum element temperature of 800C. A quartz heating element is housed in a thermally insulated cartridge for easy replacement, extending the life of the heater. Heaters are supplied with back-mounted brackets to hold support rods up to 1/2" (12.7 mm) in diameter. The lower part of the unit containing the control equipment is safely separated from the upper heating elelments by a well-ventilated air space. Units are double fused on the supply line and neutral for extra safety. Power cord is NOT included. Unit must be hard-wired.
Chemglass Life Sciences 100mL Glas-Col Heating Mantle, Series inSTMin, Spherical, 230 Watts
100mL Glas-Col Heating Mantle, Series STM, Spherical, 230 Watts, The Glas-Col Series STM mantle performs the same function as a Series TM heating mantle, plus operations requiring more heat. This mantle is useful in distillation and fractionation processes, especially when time is important. 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. Withstanding an upper internal operating temperature of 650 C, the STM mantle is very resistant to burnout. The STM mantle has a durable aluminum exterior and a resilient and pliable interior to cradle glassware. A splash guard and poncho safety shield can be used to prevent damage from accidental spills.

Andwin Scientific Heating mantles
Heating mantles are preferred to Bunsen burners or hot plates for organic liquids. They provide even heating (no hot spots) and maximum surface coverage for better temperature uniformity. The Series O spherical flask mantle covers only the flask's bottom half, letting you see its full contents. It should be used with the Series O supports. Fabric heating mantle, 200ml, 100w
