What is spot plate.?

A spot plate is a shallow, flat-bottomed dish made of glass or plastic, typically used in chemistry experiments to hold small amounts of liquid samples or reagents. It has several shallow wells or depressions on its surface, usually arranged in a regular pattern such as a grid or circular layout. These wells allow multiple samples to be arranged and observed simultaneously, making it a useful tool for performing simple qualitative tests or reactions. Spot plates are commonly used in titration experiments, acid-base reactions, and colorimetric assays. They are inexpensive, easy to clean, and can be reused many times.
