What is a spotting tile used for in science?

A spotting tile is a flat, usually ceramic or glass surface used in laboratory settings to conduct small-scale experiments or tests. It allows scientists to mix, observe, and analyze chemical reactions or biological samples in controlled conditions. Typically, spotting tiles have multiple wells or depressions for holding different substances, facilitating simultaneous experimentation. They are commonly used in chemistry and Biology for tasks such as spotting reagents or testing color changes.
