Bundesmann apparatus is a laboratory equipment used to measure the boiling point of liquids. It is made up of a thermometer and a glass test tube. The thermometer is placed into the test tube after it has been filled with the liquid sample. The thermometer is then heated until the liquid reaches the boiling point. The boiling point of the liquid is then determined by taking note of the temperature. Bundesmann apparatus aids the scientists and researchers determining the boiling point of a liquid sample precisely and conveniently.
