Gooch Crucibles, Porcelain with Cover

Gooch crucibles have a perforated bottom and include covers. Crucibles are glazed on inner and outer surfaces except for the outside bottom and rim. Used for determination of total suspended solids.

Autoclavable. Withstand temperatures to 1150° C. To prevent thermal stress cracks, we strongly recommend a heating/cooling rate not exceeding 200° C per hour.  Porcelain crucibles 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.
