The oil level is a little low now to compensate for expansion when heating commences. The Thiele tube, named after the German chemist Johannes Thiele, is a laboratory glassware designed to contain and heat an oil bath. Such a setup is commonly used in the determination of the melting point or boiling point of a substance.
Overheating the oil bath can result in a fire hazard, especially if mineral oil is being used. Generally, the maximum safe operating temperature of a mineral oil bath is approximately 160 °C (320 °F), the oil's flash point. Mineral oil cannot be used above 310 °C (590 °F) due to the compound's boiling point.
Heated bath schema. 1: Heated substance. 2: Heating medium. 3: Laboratory flask. 4: Bowl. 5: Gas burner. A heated bath is used in the laboratory to allow a chemical reaction to occur at an elevated temperature. [1] In contrast to traditional Bunsen burners, heated baths use liquids to transfer heat to the reaction vessel. This is achieved using ...
The sample is then heated, either by a heating block or an oil bath, and as the temperature increases, the sample is observed to determine when the phase change from solid to liquid occurs. The operator of the apparatus records the temperature range starting with the initial phase-change temperature and ending with the completed phase-change ...
A laboratory bath could refer to any of the following: Cooling bath: a laboratory device that lowers the temperature of the bath or improves heat conduction; Heated bath: a laboratory device that raises the temperature of the bath to enhance a chemical reaction; Laboratory water bath: a laboratory device that maintains the temperature of the bath
