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.
Agar plates may also be indicator plates, in which the organisms are not selected based on growth, but are instead distinguished by a color change in some colonies, typically caused by the action of an enzyme on some compound added to the medium. [6] The plates are incubated for 12 hours up to several days, depending on the test that is performed.
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 Petri dish (alternatively known as a Petri plate or cell-culture dish) is a shallow transparent lidded dish that biologists use to hold growth medium in which cells can be cultured, [1] [2] originally, cells of bacteria, fungi and small mosses. [3] The container is named after its inventor, German bacteriologist Julius Richard Petri.
Typically consists of a bowl, a plate with holes like a colander, and a crank with a bent metal blade which crushes the food and forces it through the holes. Funnel: Used to channel liquid or fine-grained substances into containers with a small opening. [2] A pipe with a wide, conical mouth and a narrow stem. Garlic press
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 ...
Industrial Filter press. An industrial filter press is a tool used in separation processes, specifically to separate solids and liquids.The machine stacks many filter elements and allows the filter to be easily opened to remove the filtered solids, and allows easy cleaning or replacement of the filter media.
Historic pewter, faience and glass tableware. In recent centuries, flatware is commonly made of ceramic materials such as earthenware, stoneware, bone china or porcelain.The popularity of ceramics is at least partially due to the use of glazes as these ensure the ware is impermeable, reduce the adherence of pollutants and ease washing.
