A 96-well plate is a flat plastic plate 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 ideal for high-throughput screening and assays. These plates are commonly used for tasks such as enzyme-linked immunosorbent assays (ELISA), cell culture, and drug testing. They are compatible with automated systems and can be used with various instruments, including microplate readers and pipettes, to measure reactions and analyze results efficiently.
