What is a heating mantle used for?
Heating mantles are used for heating or tempering organic liquids placed in reaction kettles, round-bottomed flasks, or relevant reaction vessels required for the boiling, evaporation, distillation, or extraction process.
What are the apparatus for heating?
Heating Devices. 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.
How does a heating mantle differ from a hot plate?
The capacity for heating mantles usually tops out at approximately 1,000mL, while hotplate stirrers can heat significantly larger volumes from 5,000mL (5L) up to about 20,000mL (20L). Because hotplates feature a flat top pan, they can be easier to clean.
Why is it important to elevate the heat source?
Raising your heat source allows you to quickly remove it in case of violent boiling or fire. If you need to cool your pot quickly, you can simply lower the jack. Without the jack, you would have to slide the hot mantle or hot plate out or lift the hot pot and risk a burn.
Why is a heating mantle better?
Advantages of using a heating mantle: Because heating mantles offer more heat contact to the glassware, they heat up more quickly and more evenly less with tendency to generate hotspots.
How do you maintain a heating mantle?
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. To prolong the life of your heating mantle, clean up spills (solid or liquid) right away.
How is a heating mantle different than a hot plate?
The capacity for heating mantles usually tops out at approximately 1,000mL, while hotplate stirrers can heat significantly larger volumes from 5,000mL (5L) up to about 20,000mL (20L). Hotplate stirrers can only be used with flat bottom glassware.
How do you treat a heating mantle?
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. To prolong the life of your heating mantle, clean up spills (solid or liquid) right away.
How hot do heating mantles get?
842 °F
Temperatures of up to +450 °C (842 °F) are possible. The heat-up time is very short which enables laboratory professionals to start their work soon. Another advantage of using a heating mantle is that the heat is distributed very evenly, which means that the danger of hotspots on the flask is eliminated.
Why is a heating mantle used instead of a hot plate for the distillation?
Heating mantles are used in place of Bunsen burners or hot plates when the sample is an organic liquid. Organic liquids have a tendency to burst into flames when exposed to direct heat, or release flammable organic vapors are heavier than air, which can explode when contacting open flames or heating coils.
