Thermal analysis results often vary due to the type and quality of the crucible used. A mismatched or low-purity crucible can cause issues like baseline drift, peak shifts, and thermal lag by disrupting heat transfer or introducing contaminants. For consistent, reliable results in DSC or TGA, use dimensionally-precise, material-certified crucibles compatible with your analyzer brand.
The most critical material properties in a thermal analysis crucible are thermal resistance, weight tolerance, chemical inertness, and heat conductivity. These directly affect the accuracy, repeatability, and stability of DSC and TGA results. High-temperature stability (up to 1600°C for zirconia), precise weight control (±0.01g), and resistance to chemical reactivity ensure reliable experimental outcomes.
Thermal analysis crucibles are small containers used to hold samples during tests like DSC, TGA, and DTA. Their material—such as platinum, alumina, or aluminum—directly affects heat transfer, chemical stability, and measurement accuracy. Proper crucible selection ensures valid and repeatable thermal analysis results across industries like pharmaceuticals, advanced materials, and battery R&D.
In pharmaceutical research, the tiniest component often carries the biggest responsibility. Thermal analysis crucibles—used in DSC and TGA—play a critical role in ensuring accurate drug stability and decomposition results. Choosing the right crucible material ensures precise heat transfer, chemical inertness, and reproducibility across experiments. This article explores how pharma labs select and use crucibles for meaningful, audit-worthy thermal testing data.
