Apr 07 2022nbsp018332The mantle will remain warm even after turning off the Variac and therefore flasks have to be removed from the mantle in order to cool Figure 152 ab Distillation using a heating mantle c Cooling of a flask after heatingSafety note the main hazard with heating mantles is that flammable organic liquids spilled on the.

As long as the fiberglass coating is not worn or broken and as long as no water or other chemicals are spilled into the mantle heating mantles pose no shock hazardAlways use a heating mantle with a variable autotransformer to control the input voltage.

Being used to heat the round bottom flaskIn 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 plateThis is a more modern version of a heating mantle with some distinct benefits.

Environmental Health and Safety Heating Mantles As long as the layers of fiberglass cloth remain intact the heating mantle will pose no shock hazardAlways use with a variable autotransformer to control the input voltage.

Examples include vacuum pumps electrophoresis devices stir plates hot plates heating mantles centrifuges UV lamps refrigerators and freezersThis equipment can pose a serious hazard if not properly maintained or improperly usedIn addition an electrical hazard could damage expensive equipment or wipe out years of research.

Except for the cord mantles are not generally repairableIf the fiberglass is brittle or cracked or if any wires are exposed discard the heating mantleNever immerse a heating mantle in water or other liquids or place these in the mantle and always use a properly grounded outlet.

For controlled mantles heating control is provided by a builtin solid state simmerstat or an Egostat energy regulator Size 4 mantles onlyFor uncontrolled mantles a range ofSubstances being heated and ensure all hazards eExplosion implosion or the release of toxic or flammable gases that might arise have been suitably.

GlasCol invented the Electric Heating Mantle in 1939 and has continued to be the industry leader for Laboratory and Industrial heating ever sinceOur products are known for exceptional performance reliability and durabilityFabric interiors conform and protect glasswareAvailable in both aluminum and fabric.

Hazards associated with the use of oil baths include hot temperatures and fireHot oil can cause severe skin burnsAccidental additions of water to a hot oil bath can cause serious splatteringMineral oil has an obnoxious smell at the elevated temperaturesReaction flasks immersed in an oil bath can become dangerous slippery.

Heating Mantle Hazard Ochem 1 lab final Flashcards QuizletAnother melting point trial of the same solid is then carried outIn the second trial the temperature is increased rapidly to 370 C and then the rate of heating is decreasedThe first drop of liquid in the sample appears at 467 C the sample is completely liquid at 48.

Heating mantle or in a water oil bath over a heating plate not touching the heating equipment to avoid overheating during the distillationAll the glass jointware should be properly adjusted avoiding any vapour leakage and the condenser must be properly fixedAfter everything set up – figure SM 2.

As long as the layers of fiberglass cloth remain intact the heating mantle will pose no shock hazardAlways use with a variable autotransformer to control the input voltageDo not exceed the input voltage recommended by the mantle manufacturerHigher voltages will cause it to overheat melt the fiberglass insulation and.

In contrast to fuses and circuit breakers a GFCI is a specialized outlet with a builtin breakerThese devices are designed to prevent shock in the event an electrical device comes in contact with waterIf the equipment were to contact with water the breaker inside the GFCI would trip automatically switching off the currentAll power outlets that could be exposed to wet conditions such as near a sink or where a leak or spillage could occur should be equipped with GFCIs.

In contrast to other heating devices such as hotplates or Bunsen burners glassware containers may be placed in direct contact with the heating mantle without substantially increasing the risk of the glassware shattering because the heating element of a heating mantle is insulated from the container so as to prevent excessive temperature gradients.

Initial heating of the unit will cause materials used in the manufacturing process to vaporize awayThis is normal and will take around 30 minutes to completely finishIt is recommended to heat the unit up while under a fume hood or in a ventilated environmentAfter the initial heating and burn off of materials the unit should not smoke.

Use a heating mantle to heat setting its height so that the mantle can be dropped down when cooling is desiredImmerse the receiving flask in ice water to minimize the escape of vapors into the labTurn on the water for the condenser and start heating the reaction vessel.

Jul 05 2017nbsp018332The common heating devices used in labs are bunsen burners hot air ovens hot plates heating mantles muffle furnaces hot oil baths and microwave digestion systemsThe selection of a device depends on the application in handHeating exposes you to burns and boils resulting from contact with hot surfaces boiling liquids vapours or flames.

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 Dangerous Substances and Explosive Atmospheres Regulations 2002 require a risk assessment of the fire and explosion hazards at a much wider range of workplaces including laboratories of all kindsHeating mantles stirrer controllersPrecautions are likely to include good handling techniques to minimise spills sills or other liquid.

These mantles enclose a heating element in a series of layers of fiberglass clothAs long as the fiberglass coating is not worn or broken and as long as no water or other chemicals are spilled into the mantle heating mantles pose no shock hazardAlways use a heating mantle with a variable autotransformer to control the input voltage.

Time to remove the heat and apply external coolingThe setup should allow for fast removal of heatA lab jack under the heating mantle is a good way to accomplish thisHazardous gases vapors dusts or fumes – whenever they are likely to be evolved an appropriate sized local exhaust system or laboratory hood must be used.
