LB medium bottle and LB agar plate Plate medium agar LB. Lysogeny broth (LB) is a nutritionally rich medium primarily used for the growth of bacteria. Its creator, Giuseppe Bertani, intended LB to stand for lysogeny broth, [1] but LB has also come to colloquially mean Luria broth, Lennox broth, life broth or Luria–Bertani medium. [2]
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.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

De Man–Rogosa–Sharpe agar, often abbreviated to MRS, is a selective culture medium designed to favour the luxuriant growth of Lactobacilli for lab study. Developed in 1960, this medium was named for its inventors, Johannes Cornelis de Man [ Wikidata ] , Morrison Rogosa [ Wikidata ] , and Margaret Elisabeth Sharpe [ Wikidata ] .
A chemistry test tube typically has a flat bottom, a round bottom, or a conical bottom. Some test tubes are made to accept a ground glass stopper or a screw cap . They are often provided with a small ground glass or white glaze area near the top for labelling with a pencil.
The idea of a Langmuir–Blodgett (LB) film was first proven feasible in 1917 when Irving Langmuir (Langmuir, 1917) showed that single water-surface monolayers could be transferred to solid substrates. 18 years later, Katharine Blodgett made an important scientific advance when she discovered that several of these single monolayer films could be stacked on top of one another to make multilayer ...
Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook ( colloq. lab notebook or lab book ) is a primary record of research . Researchers use a lab notebook to document their hypotheses , experiments and initial analysis or interpretation of these experiments.
