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 1000mL Glas-Col Heating Mantle, Series inSTMin, Spherical, 600 Watts
Mantle, Heating; Chemglass; Glas-Col; Series STM; Used in distillation, fractionation processes; w/Splash guard and poncho safety shield; For high temp. operations; Upper internal operating temp.: 650 deg. C; 1000mL; 115V, 600 watts
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.
Chemglass Life Sciences 1000mL Glas-Col Heating Mantle, Series TM, Spherical, 380 Watts
Mantle, Flask; Chemglass; Glas-Col; Series TM; Spherical; Covers only bottom half of flask; Larger sizes have multiple circuits for ease of temp. ctrl when flask is less than half full; Cap.: 1000mL; 115V, 380W
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
Chemglass Life Sciences 200mL Glas-Col Heating Mantle, Series O, Hemispherical, 100 Watts
200mL Glas-Col Heating Mantle, Series O, Hemispherical, 100 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.

Multi position combo mantle, 3 place flat bottom, 500ml, to 400 degrees C maximum internal operatng temperature. 180W, 120V
Glas Col LLC Heating Mantle
Fabric hemispherical mantle for 500ml spherical flask, heats to 400 degrees C maximum internal operating temperatue, 270W, 115V CSA
Glas Col LLC Heating Mantle
Fabric heating top for 3L flask. 115V heat to 400 degrees C internal operating temperature. This mantle helps prevent vapor condensation in the upper half of a flask during distillation of high-boiling materials. The tops are designed for use with Series M, TM, or STM mantles. They protect the flask, the solutions, and the laboratory from drafts, which would disturb the reflux ration during fractionation, from flying glass of flask implosions in high vacuum distillations, from falling objects; and, from thermal strain between top and lower half of flask during high-temperature operations. With a glass-fabric construction and laced-side opening, the elliptical hole accomodates 1-, 2-, and 3-neck flasks.All 115 volt units are CSA certified.
