Plate readers, also known as microplate readers or microplate photometers, are instruments which are used to detect biological, chemical or physical events of samples in microtiter plates. They are widely used in research, drug discovery , [ 1 ] bioassay validation, quality control and manufacturing processes in the pharmaceutical and ...
[28] [29] ELISA can also be used in toxicology as a rapid presumptive screen for certain classes of drugs. Enzyme-linked immunosorbent assay plate. The ELISA was the first screening test widely used for HIV because of its high sensitivity.

Composite microplates, including filter bottom plates, solid phase extraction (SPE) plates, and even some advanced PCR plate designs, use multiple components and/or materials which are moulded separately and later assembled into a finished product. ELISA plates may now be assembled from twelve separate strips of eight wells, making it easier to ...

A robot arm handles an assay plate. The key labware or testing vessel of HTS is the microtiter plate, which is a small container, usually disposable and made of plastic, that features a grid of small, open divots called wells. In general, microplates for HTS have either 96, 192, 384, 1536, 3456 or 6144 wells.
