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 efficient for screening and analyzing samples. These plates are commonly used for tasks such as cell culture, enzyme assays, and drug testing. They are compatible with automated systems and can be used with various instruments, including microplate readers, which measure the absorbance or fluorescence of samples in each well.
