  2. Laboratory water bath - Wikipedia

    en.wikipedia.org/wiki/Laboratory_water_bath

    A water bath operating at 72°C. A water bath is laboratory equipment made from a container filled with heated water. It is used to incubate samples in water at a constant temperature over a long period of time. Most water baths have a digital or an analogue interface to allow users to set a desired temperature, but some water baths have their ...

    The history of science during the Age of Enlightenment traces developments in science and technology during the Age of Reason, when Enlightenment ideas and ideals were being disseminated across Europe and North America. Generally, the period spans from the final days of the 16th- and 17th-century Scientific Revolution until roughly the 19th ...

  4. Citrate test - Wikipedia

    en.wikipedia.org/wiki/Citrate_Test

    This results in a change of the medium's color from green (neutral) to blue (alkaline). Bacterial colonies are picked up from a straight wire and inoculated into slope of Simmons citrate agar and incubated overnight at 37 °C. Inoculating from a broth culture is not recommended because the inoculum would be too heavy.

    Examples of target immobilization methods include affinity chromatography columns, [3] nitrocellulose binding assay filters, [2] and paramagnetic beads. [7] Recently, SELEX reactions have been developed where the target is whole cells, which are expanded near complete confluence and incubated with the oligonucleotide library on culture plates ...

    A shaker is a piece of laboratory equipment used to mix, blend, or agitate substances in a tube or flask by shaking them. It is mainly used in the fields of chemistry and biology. A shaker contains an oscillating board that is used to place the flasks, beakers, or test tubes. Although the magnetic stirrer has lately come to replace the shaker ...

  7. Total synthesis - Wikipedia

    en.wikipedia.org/wiki/Total_synthesis

    Total synthesis is the complete chemical synthesis of a complex molecule, often a natural product, from simple, commercially-available precursors. [1][2][3][4] It usually refers to a process not involving the aid of biological processes, which distinguishes it from semisynthesis. Syntheses may sometimes conclude at a precursor with further ...

  8. Streaking (microbiology) - Wikipedia

    en.wikipedia.org/wiki/Streaking_(microbiology)

    Streaking (microbiology) A plate which has been streaked showing the colonies thinning as the streaking moves clockwise. In microbiology, streaking is a technique used to isolate a pure strain from a single species of microorganism, often bacteria. Samples can then be taken from the resulting colonies and a microbiological culture can be grown ...
