Heating mantle or isomantle is a laboratory equipment used to spread heat to containers designed to distill or separate chemical fluids using heat. In the laboratory, distillation is generally used to perform fluid separation with low boiling points such as Ethanol. Ethanol has health benefits such as antiseptics, solvents of various chemicals, and more. However, the distillation process using an open fire will be perilous because the fire can break out towards organic solvent vapor. So the author innovating the heating mantle tool for distillation by using a dry heater as a heater that will heat the tube as well as monitoring the liquid temperature using the LM35 sensor with a digital timer and LCD. The study results obtained the temperature measurement results of 79 °C with an average of 79,6 °C and an error value of 0,7%. This value is still at the permissible threshold of +/−1 °C. For 2 hours 30 minutes, the timer obtained an average of 2 hours 28 minutes, and errors of 1,3 %. For ethanol amount with an average of 144 mL, after general testing, it can be concluded that heating mantle for Ethanol distillation equipped with a timer and temperature display can be appropriately used and keep on within the tolerable threshold value.
