What is microtitre plate?

A microtitre plate is a flat rectangular plate made of high-quality plastic or glass that has multiple wells or indentations arranged in orderly rows and columns, usually with up to 96 wells per plate. The wells are usually conical, circular, or square-shaped, and may range in volume from a few microliters to several milliliters.

Microtitre plates are popular in modern laboratory research and diagnostics because they allow scientists to simultaneously run multiple assays or tests using small quantities of samples or reagents. Each well in the plate is usually assigned a unique identification number or letter for easy tracking and identification of the results.

Microtitre plates are designed to fit into a specialized instrument called a microtitre plate reader or plate scanner, which can measure the optical density, fluorescence, or luminescence of each well. Microtitre plates are used in a range of scientific applications, including ELISA assays, DNA sequencing, drug screening, and high-throughput screening of small molecules.
