PL The Micro Test Plate, also known as a Spot Plate, is a laboratory tool used for performing small-scale chemical reactions and qualitative analysis. It is typically made of porcelain or durable plastic and features multiple small wells (cavities) where tiny amounts of chemicals can be tested simultaneously. This design helps in saving reagents and allows easy comparison of different reactions in a single plate. The plate is chemical-resistant, easy to clean, and ideal for use in school, college, and research laboratories for micro-level experiments and observation of color changes or precipitate formation.
