Used for pH tests or qualitative analysis of solutions for precipitate formation

The glazed surface is resistant to most organic solvents and the white background enhances the visualization of color or solid formation.

The base of the plate is unglazed

 Porcelain spotting plates made with high purity raw material.

 Uniform quality, resistant to acid and alkalai.

 Designed to withstand sudden temperature changes without cracks or deformation.

 Glazed surface with 21 mm diameter depressions.

Economical lab porcelain spotting plates are made of high purity raw material, are uniform in quality, and are resistant to acid and alkali. They're designed to withstand sudden temperature changes without cracks, explosion, or deformation. Under normal conditions, the glazed pieces can sustain a temperature of 1050°C.

 These spotting plates are available in two sizes, 12 cavity or 6 cavity.
