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

Mar 15 2017 One of the most popular and safest methods to heat a reaction mixture in a synthetic organic inorganic or organometallic laboratory is a heating mantle a resistively heated flexible fiberglass shell that conforms to the shape of the reaction flask.

May 03 2019 Precautions – Keep the heating mantle in dry place and ensure that there is no spillage of the solvents on to the surface or the heating yarn– In case of the spillage stop the operation of the unit by externally switching off the power to the unit and keep the unit to dryOperate the unit again only when it is completely dry.

Mistake not using an appropriate heat sourceSimilarly you’ll need the right heat source as it can make a world of difference to a reflux reactionOil baths and heating mantles can certainly get the job done but they come with big flawsAn oil bath runs a risk of burn injuries and can often result in messy spills.

The heating mantle should fit the flask sizeThe temperature will be difficult to control if the heating mantle lacks contact with the flaskThe heating mantle will overheat or burn out if left unintended for too long• Add the sand into the heating mantleMake sure the sand occupies 23 of the heating mantle.

Whenever possible researchers are encouraged to substitute oil baths with a safer alternative such as a sand bath or a heating mantle for solvent refluxdistillationMineral oil or silicone oil is typically used for oil baths in research labs for reactions that require heatingreflux temperatures up to 200 C.

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.
