Variac Heating Mantle

Heating Mantles Facilities Management.

A heating mantle can easily generate enough heat to vaporize most organic materials and will melt a flask if used on full powerAlways plug the heating mantle into a grounded variable voltage transformer or percentage timer control which runs at full power but cycles on and off to control the heat.

Heating Mantle With Variac.

A heating mantle which is plugged into the Variac rests on an iron ring below the distilling flaskIf youre using a stir bar then place a magnetic stirrer underneath the heating mantleLeave enough room below the iron ring so that the heating mantle can be dropped away from the distilling flask if necessary.

A Variac is a fancy type of transformer it controls the amount of electricity flowing to an applianceThey are used in the organic chem teaching labs to control heating mantles never use a heating mantle without a Variac Variacs are quite heavyIf they are dropped on the floor or the lab bench they will break.

Dec 30 2012nbsp018332The heating mantle will burn out rapidlyIt is imperative that it is plugged into a variac power controlThe size of the heating mantle has to match the size of the flaskHeating mantles that are too big or too small do not provide a good heat transfer the heating mantle will overheat and burn out quickly.

The two types of heating mantles used in the organic chemistry teaching labs are shown belowThey are shown plugged into a Variac in the back of the photo since heating mantles are NEVER plugged directly into the outletThe heating mantle on the left is covered with fabricIt comes with a detachable cord as shown in the photo below below on the left.

Variac autotransformers are designed for use at frequencies between 350 and 1200 cycles per second cps on 120voltHeattransfer characteristics exist between the coil and base and between the base and panel.
