About this item
Porcelain crucible complete with lid. Glazed both inside and outside, with the exception of the outside lower bottom and rim.
Porcelain crucibles are widely used in the chemistry laboratory
The average coefficient of expansion from 20 to 200°C is 3.56 x 10-5 gradually increasing to 4.69 x 10-5 at 1000°C. To prevent thermal stress cracks on porcelain ware, do not exceed a heating/cooling rate of 200°C per hour.
They offer excellent resistance to all reagents except hydrofluoric acid, and are highly resistant to thermal shock while having a very low coefficient of expansion.
