This white plastic spotting plate (cavity plate) has 12 depressions or cavities, each about 20 mm in diameter at the top.
Use this plastic spotting plate to perform multiple chemical reactions on very small amounts of materials. The white spot plate is especially useful to observe color change reactions. Plastic is durable and is resistant to most corrosive chemicals, but must be kept away from heat. It is also easy to clean and inexpensive if you intend to dispose them after use.
Cavity plates are suitable for observing color reactions and temporary storage of small specimens and solutions. These cavity plates are used extensively in semi-micro chemistry. They are in white color, the depressions are 22mm in diameter and 8mm deep.
