Crucibles serve as containers for samples during DSC and TGA measurements. They guarantee that the sensor is not contaminated during the measurement.
Crucible 30 uL, Alox, 20 pcs
Alumina 30 μL crucibles with lid.Set of 20 crucibles with lids. Alumina (aluminum oxide) crucibles are normally used for TGA measurements, above all when the TG signal, and not the SDTA signal, is important. After cleaning, these crucibles can be reused.
The smallest TGA crucible up to 1600 °C
Recommended for TGA or TGA/DSC measurements up to 1600 °C. In some cases good alternative for DSC measurements up to 640 °C.
Excellent thermal conductivity
The perfectly flat base and low mass make these crucibles good candidates for TGA/DSC measurements at temperatures above 600 °C.
Alumina crucibles can be reused
After the measurement, the alumina (Al2O3) crucibles can be regenerated. Often they are mechanically cleaned then rinsed in solution before drying.

No sample change prior to measurement
The alumina crucibles can be used in combination with special Al lids. They prevent sample changes during the waiting period before the measurement. This is of high relevance for samples that can take up water or samples that evaporate content.
Regeneration of alumina crucibles
After mechanical cleaning store, if needed, in water (or even in 10% hydrochloric acid). Oxides may form which can then be removed by rinsing. After drying, heat the crucibles to red hot to ensure that no weight loss occurs when they are used.
Several metals are critical
Al2O3 has the tendency to form spinels with Fe2+, Ni2+, Cu2+ and others, particularly at temperatures above 1000 °C. In addition, the melt of these metals dissolve Al2O3.
