This miniature crucible product is mainly manufactured from 99% high-purity alumina material with precision. It is specially designed for various thermal analysis instruments such as TGA, DSC, and DTA. The high-purity alumina has the properties of high temperature resistance and low thermal expansion coefficient. This enables the crucible to withstand the rapid heating and cooling of the instrument, and it is less likely to crack. As a result, the test data is more sensitive. As an experimental precision tool, it has a very small capacity and is lightweight. Its design is mainly aimed at testing small samples, in order to reduce sample consumption while still being able to fit the sample chamber size of the thermal analyzer.
