  2. Test tube - Wikipedia

    en.wikipedia.org/wiki/Test_tube

    A boiling tube is a large test tube intended specifically for boiling liquids. A test tube filled with water and upturned into a water-filled beaker is often used to capture gases, e.g. in electrolysis demonstrations. A test tube with a stopper is often used for temporary storage of chemical or biological samples.

  3. Thiele tube - Wikipedia

    en.wikipedia.org/wiki/Thiele_tube

    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. The apparatus resembles a glass test tube with an attached handle.

  4. Laboratory sample tube - Wikipedia

    en.wikipedia.org/wiki/Laboratory_sample_tube

    These tubes are usually made of glass, but can also be made of plastic or metal. They vary in size and purpose. Laboratory sample tubes must not be confused with glass tubing, which can be utilized to carry fluid between laboratory equipment. Example laboratory sample tubes are listed below: Ignition tube; Test tube; Boiling tube; NMR tube

  5. Siwoloboff method - Wikipedia

    en.wikipedia.org/wiki/Siwoloboff_method

    The Siwoloboff method is used to determine the boiling point of small samples of liquid chemicals. A sample in an ignition tube (also called a fusion tube) is attached to a thermometer with a rubber band, and immersed in a Thiele tube, water bath, or other suitable medium for heating. A sealed capillary, open end pointing down, is placed in the ...

    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 ...

  8. Melting-point apparatus - Wikipedia

    en.wikipedia.org/wiki/Melting-point_apparatus

    While the outward designs of apparatuses can vary greatly, most apparatuses use a sample loaded into a sealed capillary tube (melting-point tube), which is then placed in the apparatus. 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 ...
