A Microtiter plate or microplate is a flat plate with multiple "wells" used as small test tubes. The microplate has become a standard tool in analytical research and clinical diagnostic testing laboratories. It typically has 6, 24, 96, 384 or even 1536 sample wells arranged in a 2:3 rectangular matrix. Some microplates have even been manufactured with 3456 or even 9600 wells. Each well of a microplate typically holds somewhere between a few to a few hundred microliters of liquid.

Elisa portrayed on the cover of her album Pearl Days. ... In geometry, a rectangle is defined as a quadrilateral polygon in which all four angles are right angles. ... In mathematics, a matrix (plural matrices) is a rectangular table of numbers or, more generally, a table consisting of abstract quantities that can be added and multiplied. ...


The earliest microplate was created by a Hungarian, Dr. Takatsky, who machined 6 rows of 12 "wells" in Lucite. However, common usage of the microplate began in the late 1950s when John Liner in USA had introduced a molded version. By 1990 there were more than 15 companies producing a wide range of microplates with different features. It was estimated that 125 million microplates were used in 2000 alone.


In 1996, the Society for Biomolecular Screening (SBS) began an initiative to create a standard definition of a microtiter plate. A series of standards was completed in 2003 and published by the American National Standards Institute (ANSI) on behalf of the SBS. The standards governs various characteristics of a microtiter plate including well dimensions (e.g. diameter, spacing and depth) as well as plate properties (e.g. dimensions and rigidity). The American National Standards Institute or ANSI (pronounced an-see) is a nonprofit organization that oversees the development of standards for products, services, processes and systems in the United States. ... Diameter is an AAA (authentication, authorization and accounting) protocol for applications such as network access or IP mobility. ... Graph theory is a growth area in mathematical research, and has a large specialized vocabulary. ...


A number of companies have developed robots to specifically handle SBS microplates. These robots may be liquid handlers which aspirate or dispense liquid samples from and to these plates, or "plate movers" which transport them between instruments. A robot is an electro-mechanical device that can perform autonomous or preprogrammed tasks. ...


Instrument companies have designed plate readers which can detect specific biological, chemical or physical events in samples stored in these plates. Plate readers (also know as microplate readers) are laboratory instruments designed to detect biological, chemical or physical events in samples stored in microtiter plates. ...
