White cavity spot plates are usually used for agglutination, flocculation, and precipitation. P.I.P. White Cavity Spot Plates are resistant to most of the common laboratory acids and chemicals, and have circular cavities. These plates are suitable for different tests such as VDRL test, pH tests, and quantitative chemical analysis for precipitation. They are also ideal for observing staining reactions, temporary storage of small amounts of samples or solutions and also combining samples and stains. These plates are available in two models of 10 and 12-cavity. The 12-cavity model has alphanumeric grid for easy retrieval.
