2. Thiele tube - Wikipedia

   en.wikipedia.org/wiki/Thiele_tube

   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.

3. Melting-point apparatus - Wikipedia

   en.wikipedia.org/wiki/Melting-point_apparatus

   A Fisher–Johns apparatus. A melting-point apparatus is a scientific instrument used to determine the melting point of a substance. Some types of melting-point apparatuses include the Thiele tube, Fisher-Johns apparatus, Gallenkamp (Electronic) melting-point apparatus and automatic melting-point apparatus.

4. Oil bath - Wikipedia

   en.wikipedia.org/wiki/Oil_bath

   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.

5. Heated bath - Wikipedia

   en.wikipedia.org/wiki/Heated_bath

   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 a high-boiling point liquid inside a thermally conducting bath (usually made of metal).

6. Round-bottom flask - Wikipedia

   en.wikipedia.org/wiki/Round-bottom_flask

   Round-bottom flasks are often used to contain chemical reactions run by chemists, especially for reflux set-ups and laboratory-scale synthesis. [3] Boiling chips are added in distilling flasks for distillations or boiling chemical reactions to allow a nucleation site for gradual boiling. This nucleation avoids a sudden boiling surge where the ...

7. Test tube - Wikipedia

   en.wikipedia.org/wiki/Test_tube

   A boiling tube is essentially a scaled-up test tube, being about 50% larger. They are designed to be wide enough to allow substances to boil violently as opposed to a test tube, which is too narrow; a boiling liquid can explode out of the end of test tubes when they are heated, as there is no room for bubbles of gas to escape independently of ...

8. Condenser (laboratory) - Wikipedia

   en.wikipedia.org/wiki/Condenser_(laboratory)

   In chemistry, a condenser is laboratory apparatus used to condense vapors – that is, turn them into liquids – by cooling them down. [1] Condensers are routinely used in laboratory operations such as distillation, reflux, and extraction. In distillation, a mixture is heated until the more volatile components boil off, the vapors are ...
