  2. Plate count agar - Wikipedia

    en.wikipedia.org/wiki/Plate_count_agar

    The pour plate technique is the typical technique used to prepare plate count agars. Here, the inoculum is added to the molten agar before pouring the plate. The molten agar is cooled to about 45 degrees Celsius and is poured using a sterile method into a petri dish containing a specific diluted sample.

  3. Wilhelmy plate - Wikipedia

    en.wikipedia.org/wiki/Wilhelmy_plate

    The Wilhelmy plate consists of a thin plate usually on the order of a few square centimeters in area. The plate is often made from filter paper, glass or platinum which may be roughened to ensure complete wetting. In fact, the results of the experiment do not depend on the material used, as long as the material is wetted by the liquid. [1]

  4. Agar plate - Wikipedia

    en.wikipedia.org/wiki/Agar_plate

    The plates are incubated for 12 hours up to several days, depending on the test that is performed. Commonly used types of agar plates include: Red blood cells on an agar plate are used to diagnose infection. On the left is a positive Staphylococcus infection, on the right a positive Streptococcus culture.

  5. Polished plate glass - Wikipedia

    en.wikipedia.org/wiki/Polished_plate_glass

    Mirror plates prior to the invention had been made from blown "sheet" glass, and were consequently very limited in size. De Nehou's process of rolling molten glass poured on an iron table rendered the manufacture of very large plates possible. [2] In 1773 English polished plate (by the French process) was produced at Ravenhead.

  6. Pour point - Wikipedia

    en.wikipedia.org/wiki/Pour_point

    The sample is then cooled and inspected for pour point as per the usual pour point method. The method usually gives higher pour point because the thermal history has not been cancelled by a prolonged thermal treatment. The lower pour point is measured by first pouring the sample into a stainless steel pressure vessel. The vessel is then screwed ...

  7. Plate theory - Wikipedia

    en.wikipedia.org/wiki/Plate_theory

    The typical thickness to width ratio of a plate structure is less than 0.1. [citation needed] A plate theory takes advantage of this disparity in length scale to reduce the full three-dimensional solid mechanics problem to a two-dimensional problem. The aim of plate theory is to calculate the deformation and stresses in a plate subjected to loads.

  8. Spot plate - Wikipedia

    en.wikipedia.org/wiki/Spot_plate

    A spot plate, also called a reaction plate, color test plate, [1] or spotting tile (British English), is a laboratory tool made either from ceramics or plastics. [2] Each plate consists of many cavity-like depressions in which only small amount of reactants can be added at a time. [ 3 ]

  9. Blown plate glass - Wikipedia

    en.wikipedia.org/wiki/Blown_plate_glass

    Blown plate was made by hand-grinding broad sheet glass. As the process was labour-intensive, and expensive, blown plate was mainly used for carriages and mirrors rather than in windows for buildings. [1] Other methods for making hand-blown glass included: broad sheet, crown glass, polished plate and cylinder blown sheet. These methods of ...
