Laboratory porcelain Spotting plates,high strength and porcelain evaporating dish,outstanding qualtity

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 unglazedPorcelain 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.
