Safety Precautions Heating mantles should never be plugged directly into an outlet. A heating mantle can easily generate enough heat to vaporize most organic materials and will melt a flask if used on full power.
1.The heating mantle with a fixed housing, which is particularly suitable for the tasks when the laboratory device can be placed on a table. 2.The heating mantle, also called the heating jacket, which is used when the heating element can be firmly fixed around the round bottom flask. Precautions for Using a Electric Heating Mantle. Jan 25
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

Jun 01, 2021· Most oil baths are good for heating reactions <200 oC as they provide a more even distribution of heat and are easier to regulate. F or reactions requiring higher temperatures, heating mantles and sand or salt baths must …
1. Always use a heating mantle with a variable autotransformer to control the input voltage. Never plug them directly into a 110-V line. 2. Be careful not to exceed the input voltage recommended by the mantle manufacturer. Higher voltages will cause it to overheat, melt the fiberglass insulation and expose the bare heating element. 3.
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 …
Point the funnel away from the eyes and the naked flames, or heating mantle. 5.6.2 Observe special precautions when handling new organic substances of which the toxic hazards are unknown. 5.6.3 Protective eye goggles and gloves must be worn. 5.6.4 Always use appropriate pipette filler. Never fill pipette using the mouth.
Jul 05, 2017· The common heating devices used in labs are bunsen burners, hot air ovens, hot plates, heating mantles, muffle furnaces, hot oil baths and microwave digestion systems. The selection of a device depends on the appliion in hand. The risks posed by the common heating devices and precautions to be taken in their handling are discussed
Basic Precautions: Periodically test the function of the "off" switch on each hot plate, heating mantle, and water bath to verify that it works and the device cools off quickly when the switch is in the "off" position.

Jan 25, 2019· The following are precautions when using a heating mantle. I hope it would provide some help for everyone. The instrument should be placed on a flat and stable ground. Plug in the power and turn on the switch. The green light indies power …
Heating control is provided either by a regulator built into the heating mantle (Fig. 5.13a) or by an external controller, which is connected to the mantle by a plug. Some mantles, ''stirrer mantles'', have a built-in magnetic stirrer just like …
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 dry. Operate the unit again only when it is completely dry.
Most labs use at least one type of heating device, such as ovens, hot plates, heating mantles and tapes, oil baths, salt baths, sand baths, air baths, hot-tube furnaces, hot-air guns and microwave ovens. A nuer of general precautions need to be taken when working with heating devices in the laboratory.
The heating mantle should fit the flask size. The temperature will be difficult to control if the heating mantle lacks contact with the flask. The heating mantle will overheat or burn out if left unintended for too long. • Add the sand into the heating mantle. Make sure the sand occupies 2/3 of the heating mantle. Figure 1 Reflux Apparatus

1. Always use a heating mantle with a variable autotransformer to control the input voltage. Never plug them directly into a 110-V line. 2. Be careful not to exceed the input voltage recommended by the mantle manufacturer. Higher voltages will cause it to overheat, melt the fiberglass insulation and expose the bare heating element. 3.
leave any heating apparatus unattended during operation. AVOID SPILLAGES: Always fill the glassware / vessel away from the heating mantle. Only introduce a pre-filled, clean, wiped-dry flask into the heating mantle. If spillage does occur, disconnect unit from the power supply and follow instructions in the Servicing and Repair section.
