  2. Hot plate - Wikipedia

    en.wikipedia.org/wiki/Hot_plate

    A hot plate or hotplate is a heated flat surface on a stove or electric cooker on which food may be cooked. [3] It comprises a heated top which is flat and usually circular, and may be made of metal, ceramic, or heat-resistant glass, with resistive wire forming a heating element fitted underneath and a thermostat to control the temperature.

  3. Evaporating dish - Wikipedia

    en.wikipedia.org/wiki/Evaporating_dish

    An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, [a] and sometimes to their melting point.Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.

  4. Magnetic stirrer - Wikipedia

    en.wikipedia.org/wiki/Magnetic_stirrer

    In synthetic chemistry, a combined magnetic stirrer/heater, equipped with a built-in temperature control mechanism and temperature probe, is commonly used with a heating bath (commonly oil, sand, or low-melting metal) or cooling bath (commonly water, ice, or an organic liquid mixed with liquid nitrogen or dry ice as coolant), allowing reactions ...

  5. Sand bath - Wikipedia

    en.wikipedia.org/wiki/Sand_bath

    A sand bath is most commonly used in conjunction with a hot plate or heating mantle. A beaker is filled with sand or metal pellets (called shot) and is placed on the plate or mantle. The reaction vessel is then partially covered by sand or pellets. The sand or shot then conducts the heat from the plate to all sides of the reaction vessel.

  6. Oil bath - Wikipedia

    en.wikipedia.org/wiki/Oil_bath

    These baths are commonly used to heat reaction mixtures more evenly than would be possible with a hot plate alone, as the entire outside of the reaction flask is heated. . Generally, silicone oil is used in modern oil baths, although mineral oil, cottonseed oil and even phosphoric acid have been used in the p

  7. Shaker (laboratory) - Wikipedia

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

    The liquids to be stirred are held in beakers, jars, or Erlenmeyer flasks that are placed over the table or, sometimes, in test tubes or vials that are nested into holes in the plate. [3] Platform shakers can also be combined with other systems like rotating mixers for small systems and have been designed to be manufactured in laboratories ...

  8. Crucible tongs - Wikipedia

    en.wikipedia.org/wiki/Crucible_tongs

    Crucible tongs are used most often with crucibles, small ceramic or metal vessels used to heat chemicals to temperatures up to 565.56 degree Celsius. [3]As a crucible will be very hot when heating it in a furnace or a Bunsen burner, one cannot hold the crucible directly.

  9. Heated bath - Wikipedia

    en.wikipedia.org/wiki/Heated_bath

    The heated bath is heated on an electric hot plate, or with a Bunsen burner. The reaction vessel (Florence flask, Erlenmeyer flask, or beaker) is immersed in the heated bath. A thermometer is usually kept in the fluid to monitor the temperature.
