In terms of material purity, Mettler alumina crucibles are made from high-purity alumina powder through precision high-temperature sintering technology, with extremely low impurities such as SiO ₂, ensuring that the crucible does not undergo physical or chemical reactions with the analyzed sample at high temperatures. For example, its 900 μ L alumina crucible can withstand high temperatures of 1600 ℃ and is suitable for testing conditions such as molten metals. Special alumina crucibles can even be used stably in an environment of 1800 ℃, meeting high-precision experimental requirements such as TGA (thermogravimetric analysis).

In terms of geometric design, the Mettler alumina crucible adopts a flat bottom structure with a flatness deviation of ≤ 0.02mm at the bottom, ensuring close contact with the sensor and minimal temperature gradient. At the same time, crucibles are available in various volume specifications, ranging from 30 μ L to 900 μ L, to meet different quantity requirements. For example, small volume crucibles (such as 30 μ L) have high resolution and are suitable for detecting weak thermal effects; Large volume crucibles (such as 900 μ L) are suitable for non-uniform samples or experiments that require more diverse quantities. In addition, the crucible can be equipped with a dedicated aluminum cover or alumina cover, which can be removed through an automatic sampler to further optimize the experimental process.

In terms of thermal performance, Mettler alumina crucibles have high thermal conductivity, with rapid heat transfer between the sample and the crucible, minimal temperature difference, and uniform temperature distribution. Its dense and uniform microstructure ensures that no peaks appear during use, avoiding interference with experimental results. Meanwhile, the crucible can be reused, and after washing with water or 10% hydrochloric acid and drying, it does not affect the experimental results, significantly reducing the cost of use.
