Crucibles serve as containers for samples during DSC and TGA measurements. They guarantee that the sensor is not contaminated during the measurement.
Crucible 150 uL, Pt, 4 pcs
Pt 150 μL crucibles.Set of 4 crucibles with lids. Platinum crucibles are mainly used for TGA or DSC measurements at temperatures above 640 °C. SDTA and DSC curves measured with platinum crucibles are usually better than those obtained using crucibles made of alumina.
For measurements above 640 °C
Platinum (or more precisely PtRh 80:20%) crucibles are mainly used for TGA/DSC or TGA measurements at temperatures above 640 °C.
High enthalpy result quality
Enthalpy results obtained with platinum crucibles are normally better than with AlOx crucibles due to better thermal conductivity.
PtRh crucibles for humidity applications
For humidity measurements with salts, PtRh crucibles are the best choice. Pt crucibles are not recommended in combination with metals.

Wet chemistry and ash testing
Typical applications that are performed with Pt/Rh crucibles lie in the field of wet chemistry. In addition, ash testing is often performed with Pt/Rh.
PtRh crucibles can be reused
After the measurement, the PtRh crucibles can be regenerated. Often they are mechanically cleaned, then rinsed in aqueous solution before drying them.
Pt forms easily alloys with other metals
Molten metals form alloys with platinum very easily. This can result in a hole being formed in the bottom of the crucible. In addition, also non-metals can act as Pt poisons such as soot or carbon black (particularly in non-oxidizing conditions).
Care with PtRh crucibles and Pt sensors
At temperatures above 1100 °C, PtRh crucibles can "stick" to the crucible holder made of Pt (SDTA, DTA). This can be prevented by placing a sapphire disk (ArtNo: 17759) on the crucible holder.
Regeneration procedure of PtRh crucibles
After mechanical cleaning, PtRh crucibles are often rinsed in water or hydrochloric acid (up to 10%) for several hours. After drying, heat the crucibles to red hot to ensure that no weight loss occurs when they are used.
