A ceramic plate with small wells or depressions built into it, often used for qualitative analysis.

The wells (or spots) are used to perform reactions on a very small amount of materials. These were extensively used in the past for chemical reactions to determine mineral or drug content (for example the treatment of a small amount of solid with an acid to view the bubbles of Carbon dioxide that are given off).

The plate is usually white in color to make the formation of colors easier to see. Some plates are black to make the formation of white precipitates easy to view.

Some labs now use plastic plate for the same purpose.
