Product information

A small amount of reagent is dropped into the cavity with a dropper to allow the reaction to take place. If the product is colored precipitation, white Spotting plate is used, and if the product is white or light yellow precipitation, black Spotting plate should be used. Sometimes according to the color of the color plate referred to as white porcelain plate, black porcelain plate.

According to the specifications, it should have a white background with a whiteness greater than 95, no fluorescence, no obvious directional reflection, and can be made of either paper or plastic. In colorimetry, it serves as both a container and a white background, while also providing some shade from the influence of other light in the environment.

Product Details

High Temperature Resistance
