A "96-well" plate is a flat plastic dish used in laboratories for various experiments, particularly in biology and chemistry. It contains 96 small wells arranged in an 8x12 grid, allowing researchers to conduct multiple tests simultaneously. Each well can hold a small volume of liquid, making it efficient for screening and analyzing samples. These plates are commonly used in applications like enzyme-linked immunosorbent assays (ELISA), cell culture, and DNA amplification. The design facilitates easy handling and automation, as many laboratory instruments are compatible with 96-well plates, streamlining the research process and increasing productivity.
