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.
A few Babcock bottles are on the counter, just below center. A Babcock bottle is a clear glass flask with a long graduated neck, used in the Babcock test to evaluate the cream contents of milk. [1] It is also called a Babcock milk test bottle, milk test bottle, cream test bottle, and other similar names. [2] [3] [4] [5]
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

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.
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 ...
used for simultaneous solid and liquid cultures in many bottles Centrifuge: to separate supernatant & pellet Cragie tube: see link: Desiccator: to dry things Durham's tube: used to detect gas production in sugar fermentation media; the tube is placed in an inverted fashion so that gases produced get trapped in it and do not float away to the ...
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 .
