    en.wikipedia.org/wiki/Reagent_bottle

    A reagent bottle is a type of laboratory glassware. The term "reagent" refers to a substance that is part of a chemical reaction (or an ingredient of which), and "media" is the plural form of "medium" which refers to the liquid or gas which a reaction happens within, or is a processing chemical tool such as (for example) a flux.

    Reagent bottles are containers with narrow openings generally used to store reagents or samples. Small bottles are called vials. Jars are cylindrical containers with wide openings that may be sealed. Bell jars are used to contain vacuums.

  4. Blue bottle experiment - Wikipedia

    en.wikipedia.org/wiki/Blue_bottle_experiment

    Blue bottle reaction video. The blue bottle experiment is a color-changing redox chemical reaction. An aqueous solution containing glucose, sodium hydroxide, methylene blue is prepared in a closed bottle containing some air. Upon standing, it spontaneously turns from blue to colorless due to reduction of methylene blue by the alkaline glucose ...

  5. Laboratory flask - Wikipedia

    en.wikipedia.org/wiki/Laboratory_flask

    Reagent flasks are usually flat-bottomed flasks, which can thus be conveniently placed on the table or in a cabinet. These flasks cannot withstand too much pressure or temperature differences, due to the stresses which arise in a flat bottom; these flasks are usually made of weaker glass than reaction flasks.

    en.wikipedia.org/wiki/Round-bottom_flask

    Flat-bottomed flask: A flask with similar uses as the round-bottom flask, but with a flat bottom that allows it to stand on a level surface.; Florence flask: A flask similar to the flat-bottomed flask that has round bodies and either a round bottom or a flat bottom so that one can stand the flask on a level surface.

    en.wikipedia.org/wiki/Winkler_titration

    A Winkler bottle is a piece of laboratory glassware specifically made for carrying out the Winkler test. These bottles have conical tops and a close fitting stopper to aid in the exclusion of air bubbles when the top is sealed.

  8. Cuvette - Wikipedia

    en.wikipedia.org/wiki/Cuvette

    Cuvettes to be used in circular dichroism [5] experiments should never be mechanically stressed, as the stress will induce birefringence [6] in the quartz and affect measurements. Analyses are performed by using a conventional scanning spectrophotometer and the usual laboratory cuvette (special vial) that fits into the sample cavity of the ...

  9. Wash bottle - Wikipedia

    en.wikipedia.org/wiki/Wash_bottle

    A wash bottle is a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks. Wash bottles are sealed with a screw-top lid. When hand pressure is applied to the bottle, the liquid inside becomes pressurized and is forced out of the nozzle into a narrow stream of liquid.
