Size: 19mm (3/4 inch), 25mm (1 inch), 38mm (1-1/2 inch)
Advantage
● These media are made from chemical porcelain and have excellent resistance to acids except in the case of hydrofluoric acid.
● Moisture absorption must less than half a percent.
● The porcelain’s specific gravity is 2.25-2.35g/cm3 and an average heat capacity (between 20℃ and 500℃of 0.22 cal/g.℃)
