Round form evaporating dishes include lip. Dishes from 35ml to 250ml capacity are glazed inside and outside. Dishes 385ml and larger are glazed inside and partially outside.
Autoclavable. Withstand temperatures to 1150° C. To prevent thermal stress cracks, we strongly recommend a heating/cooling rate not exceeding 200° C per hour. United porcelain evaporating dishes offer excellent resistance to acids and alkalies except for hydrofluoric acid.
Thermal Shock Resistance - average coefficient of expansion from 20° C to 200° C is 3.56 x 10-5, gradually increasing to 4.69 x 10-5 at 1050°C. Every batch of porcelain is heat tested in our factory.
Glaze - No softening occurs up to 1000°C, and it is extremely white.
Resistance to Chemical Action - Resistance to acids and alkalies is excellent, except for hydrofluoric acid.
