Spot Plate, Porcelain, Black 12 Wells, 1 Each

The Spot Plate, Porcelain, Black 12 Wells by United Scientific is a reusable 118 x 91 mm porcelain plate with 12 wells of about 1.5 mL each. Its black surface makes white precipitates and pale color changes easier to see than on a white plate, and the porcelain resists heat and chemicals. Chemistry teaching labs use it for qualitative analysis and drop-scale reactions.
