If the magnetic coupling to the stir bar is lost for any reason, the stir speed…, …Heating and stirring functions are independently controlled by 2 separate knobs. The mantles should never be connected directly to the outlet, but first to a "Variac" (blue piece of equipment in Figure 1.51b) which then connects to the outlet and delivers variable voltage to the mantle. The mantles are cup-shaped and designed for different sizes of round bottomed flask (Figure 1.51a). Choose from flexible fabric or canister-style lab heating mantles. Mantle can be used in a wide range of ambient…, Related Products: Soxhlet Extraction Apparatus, …round bottom flask of 250ml, 500ml or 1000ml capacity to be stirred and heated up to an element temperature of 450°C through precise electronic control, giving an accurate measure of temperature and stirring. It comes with a detachable cord, as shown in the photo below below on the left. A heating mantle, or isomantle, is a piece of laboratory equipment used to apply heat to containers, as an alternative to other forms of heated bath. This type of heating mantle is … Heating Mantles. Because of the problems stated above for the fabric-style heating mantles, the organic chemistry teaching labs have mostly replaced them with rigid heating mantles. The two types of heating mantles used in the organic chemistry teaching labs are shown below. Original content © University of Colorado at Boulder, Department of Chemistry and Biochemistry.

Sand baths provide uniform heating for any size small container, due to the much higher surface contact. There are many instances when heat is needed in a laboratory practical, it is needed to reflux reaction mixtures, to distil liquids as well as help to dissolve solids in recrystallisations. Choose from spherical and lower hemisphere heating mantles with 850°F maximum temperature capacities and molded fiberglass liners that can fit snugly on round-bottom flasks. (1) 1 product ratings - 2000ml Heating Mantle with Magnetic Stirrer 98-II-B Series 450℃ Max 450W 110V Lisa Nichols (Butte Community College). The mantles are cup-shaped and designed for different sizes of round bottomed flask (Figure 1.51a). Choose from flexible fabric or canister-style lab heating mantles. Safety note: the main hazard with heating mantles is that flammable organic liquids spilled on the surface of a hot mantle do have the possibility of ignition. You have selected the maximum number of items to compare. By controlling the delivered voltage, Variacs are used to regulate the temperature of a heating mantle. Our products are known for exceptional performance, reliability and durability. If you are looking for an accurate and easy-to-use heating solution, a lab heating mantle is a good alternative to heating baths. If a mantle does not fit a round bottomed flask perfectly, sand can be added to ensure good thermal contact (Figure 1.51c). Replace messy oil baths, heating mantles, avoid spills and make your chemistry safer, cleaner and faster It is accepted that oil baths and heating mantles are no longer the preferred choice of chemists to heat … The mantles are cup-shaped and designed for different sizes of round bottomed flask (Figure 1.51a).
