  2. Condenser (laboratory) - Wikipedia

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

    The two hoses connected to the condenser circulate water through the space between the inner and outer walls. 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 ...

  3. Liebig condenser - Wikipedia

    en.wikipedia.org/wiki/Liebig_condenser

    Water (or some other fluid) is constantly circulated in the jacket to carry away the heat of vaporization released by the condensing vapor, keeping the tube below the liquid's boiling point. The condensed liquid drips out of the lower end of the inner tube. The Liebig condenser can also be used in reflux or Soxhlet extraction operations ...

  4. Alcohol burner - Wikipedia

    en.wikipedia.org/wiki/Alcohol_burner

    An alcohol burner or spirit lamp is a piece of laboratory equipment used to produce an open flame. ... A small amount of liquid is boiling above the alcohol burner.

  5. Thiele tube - Wikipedia

    en.wikipedia.org/wiki/Thiele_tube

    A Thiele tube can be used to measure the boiling point of a liquid by the Siwoloboff method. A sample in a fusion tube is attached to a thermometer with a rubber band, and immersed in the tube. A sealed capillary, open end pointing down, is placed in the fusion tube. The Thiele tube is heated; dissolved gases evolve from the sample first.

  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 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.

  8. Ebulliometer - Wikipedia

    en.wikipedia.org/wiki/Ebulliometer

    Ebulliometer of Świętosławski. In physics, an ebulliometer (from Latin ēbullīre 'to boil') is an instrument designed to accurately measure the boiling point of liquids by measuring the temperature of the vapor–liquid equilibrium either isobarically (at constant pressure) or isothermally (at constant temperature).
