Reflux Heating Mantle

Reflux Heating Mantle

2. For casein or gelatin, carefully heat the mixture under reflux for 35 minutes using a heating mantle or a very small flame. For hair or silk, heat the mixture under reflux for 50 minutes. 3. After the reflux period is completed, the hydrolysate must be decolorized. Add about 0.5 g of decolorizing carbon to the hot hydrolysate and swirl the ...

A heating mantle is laboratory equipment used to heat the liquids in the flask using electricity. The first heating mantle was invented in 1972 by Michael Kort Rijk and Paul Leonard Johnson, two scientific researchers of England . The heating mantle is also known as isomantle or heating jacket is designed for advanced laboratory usage.

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.

Oct 03, 2021 When heating liquids above 100 C, this is the approach to use. For these temperatures, heating mantles are the ideal option, as long as the flask is the right size to suit the mantle. Heat is transferred from the hotplate to the reaction vessel via the sand. They take a long time to heat up and cool down, which is a negative.
