Porcelain Desiccator Plate, Plate Diam. 190 mm, No. of Holes, 7, Coorstek (CAT#: STEM-GLE-0730-LKN)

Chemical porcelain has an average coefficient of expansion from 20°C to 200°C is 3.56 x 10-6, gradually increasing to 4.69 x 10-6 at 1000°C. Note: To prevent thermal stress cracks on porcelain ware it is strongly recommended a heating/cooling rate not to exceed 200°C/hour.
30 mm diam. holes on the desiccator plate can hold crucibles, bottles, or vials. Has a glazed top surface, with feet 16 mm H, for stability.
