Heating Mantle

Isomantle or a heating mantle is a chunk of laboratory equipment utilized to apply heat to containers, as an option to other shapes of the heated bath. At Kumar Instruments, Heating mantles may have different forms. In 1972, the first heating mantle was invented by two scientific researchers of England by Michael Kort Rijk and Paul Leonard Johnson.

Heating mantles evenly heat liquids within funnels, flasks, containers, and other glassware. Capacities typically range from 1,000mL to 100mL. They are also obtainable in versions without or with stirring capabilities.

What is the role of the heating mantle?

Heating mantles are utilized for tempering or heating organic liquids put down irrelevant reaction vessels, reaction kettles, or round-bottomed flasks needed for the extraction, distillation, evaporation, or boiling process.

What is a heating mantle made of?

One of the safest and famous processes to heat a reaction mixture in a manmade organometallic, organic, or inorganic laboratory is a heating mantle, a resistant heated pliable fiberglass shell that follows the shape of the reaction flask.

Do you need a heating mantle?

The Scientific Instruments precisely fits the purification and boiling flask with a round bottom providing controllable and compatible heating. Using a heating mantle is a moderately secured manner for heating organic liquids. Organic liquids have a likelihood to burst when exposing out to head-on heat.

Why is a heating mantle utilized for distillation?

Heating mantles are a remarkably protected way to heat burnable or combustible organic liquids in a round-bottomed flask. The mantles are designed for different sizes of the round-bottomed flask and are mostly cup-shaped. … By controlling the delivered voltage, they are utilized to manage the temperature of a heating mantle.

Advantages of using a heating mantle: 

  • Because heating mantles offer more heat contact to the glassware, they heat up more swiftly and more evenly less with tendency to give rise to hotspots.
  • A common mantle is one of the hottest accessible laboratory heating devices as temperature range might be anything from 450°C all the way up to 0°C.
  • Do only be utilized with flat bottom glassware.

How do you use heat mantle?

To heat an item, it is fixed up within the basket of the heating mantle. Applying a heating mantle gives rise to no liquid residue to drip off the flask. Also, mantles usually scatter heat uniformly over the plane surface of the flask and show a lesser inclination to generate dangerous hotspots.

Types of Heating mantles

It is either found in rigid or fabric form. Fabric ones are generally flexible and can be shaped to fit in with a wide range of flask sizes. When it comes to rigid ones, they are developed to shape up in a particular flask size or can be plainly filled with sand to accommodate varying sizes. The sand also assists in the constant heating of the liquid.
Metal-housed mantles are convenient for laboratory settings including development and research labs. They are is made to fit flasks with capacities between 6,000 ml to 50 ml. They offer high-temperature capabilities up to 450° C. Metal-housed heating mantles have built-in controllers and are available in tabletop designs.
