A 96-well plate is a flat 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 made from materials like polystyrene and can be treated for specific applications, such as cell culture or binding assays. They are often used with equipment like microplate readers to analyze the results, making them essential tools in biotechnology and pharmaceutical research.
