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 HM-200-MP6-250-115 Extraction Heater, 6 Positions, 250 mL; 115 VAC
Regulating the heat on these multiposition extraction mantles is simple using the built-in solid-state electronic controls. The units accept round-bottom flasks ranging from 100 to 1000 mL. Select an extraction heater depending on the size of your flask. Extraction heaters feature an independent heater per mantle, allowing liquids with different boiling points to be heated alongside each other. Each heater has its own control dial and on/off indicator light, and can reach up to a maximum element temperature of 450C (842F). The control panel is safely separated from the 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.
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
Cole-Parmer SHM-250D-1000 Digi-Kit Stirring/Heating Kit, 1000 mL; 230 VAC
Designed to provide a comprehensive answer to heating and stirring fluids in various vessel formats. This product is modular in design, allowing for complete interchangeability between mantles of various sizes. When the temperature probe is fitted, the heating is controlled via the temperature feedback circuit and the actual temperature is displayed on the controller. A temperature probe may be used to gauge the temperature of the flask contents more accurately (up to 220C) Choose from three heater cartridge sizes, accommodating 100 to 250 mL, 500 mL, or 1000 mL round bottom flasks.
