Heating Mantle Precautions

Apr 10, 2003 The heating mantle should fit the flask size. A heating mantle that is either too small or too big, has a poor contact with the flask, which damages the heating mantle. In addition, the temperature is very difficult to control. The lack of contact causes the heating mantle to overheat and burn out. A heating mantle that is slightly ...

being used to heat the round bottom flask. In your equipment set up (or any of the others), the heating mantle and heating controller will be replaced by an engineered (shaped) aluminium block sitting on the top of a stirrer hot plate. This is a more modern version of a heating mantle with some distinct benefits. Distillation of a Pure Liquid

General Precautions. When working with heating devices, consider the following: ... Heating Mantles. Heating mantles are commonly used for heating round-bottomed flasks, reaction kettles and related reaction vessels. These mantles enclose a heating element in a series of layers of fiberglass cloth. As long as the fiberglass coating is not worn ...

Glas-Col invented the Electric Heating Mantle in 1939 and has continued to be the industry leader for Laboratory and Industrial heating ever since. Our products are known for exceptional performance, reliability and durability. common sizes available. fabric interiors conform and protect glassware. available in both aluminum and fabric ...

Handling Precautions. Avoid accumulation of vapors and to control sources of ignition including: open flames; electrical equipment; ... Steam baths, salt and sand baths, oil and wax baths, heating mantles and hot air or nitrogen baths are preferable. Minimize the production of vapors and the associated risk of ignition by flashback. Vapors from ...

Heating Mantle. In case of heating mantle it goes about a device which is used in laboratories to heat special media in glass vessels. Due to the various sizes of the glass vessels the exact amounts of liquids can be heated. The scope of volumes of heating mantle at PCE ranges from 100 ml up to 10

Heating mantles are the most common method for heating reaction vessels in the laboratory. For more about the practical aspects of these devices, see the Heating Sources Page of our Glassware Gallery.. All heating mantles and tapes must be operated through a power control.These are not designed to be plugged directly into an electrical outlet.Chemical …

Lab heating mantles are used to uniformly heat various lab and glassware vessels. If you are looking for an accurate and easy-to-use heating solution, a lab heating mantle is a good alternative to heating baths. A lab heating mantle is even great for hard-to-fit flasks and funnels. Choose from flexible fabric or canister-style lab heating mantles.

Mar 09, 2008 Keep away from heat, sparks, and sources of ignition. The small fire in the first example would not have happened if the ignition source had been properly controlled. The major fire in the second example was ignited by the transformer which powered the heating mantle. The transformer was in the hood immediately adjacent to the distillation ...

MilliporeSigma. Economical and dependable. These mantles have a ceramic heat cavity (resistance wire completely embedded), a grounded metal housing for safer operation, a low profile that permits magnetic stirring, and can be operated at up to 550 C. May be used as an air or sand bath. All models have a 36 in.,….

Much of this cannot be avoided, and may well not be available in ignition-protected form, eg hot plates, heating mantles, stirrer controllers. Precautions are likely to include: good handling techniques to minimise spills, sills or other liquid retaining methods to minimise liquid spread, proper support for glass equipment, placing electrical ...

Why would the chemist raise the heating mantle to the reaction vessel rather than lowering the reaction vessel to the heating mantle? If the reaction becomes overheated, it is much faster to lower the lab jack and thus the heat source from the reaction mixture than it is to move the entire distillation apparatus away.
