How to Select Crucibles for DSC and TGA Testing in Material Science?

Material science labs focus on reproducibility and clear measurements. The type of crucible directly affects the sensitivity and repeatability of both DSC and TGA methods.

For DSC and TGA, aluminum crucibles are commonly used for general polymer, resin, and organic tests because they conduct heat well and are cost-effective. Platinum crucibles are better for high-purity or high-temperature studies. Always match the crucible to your test for reliability (Differential Scanning Calorimetry).

Test Type	Material	Max Temperature (°C)	Main Benefit	Common Use
DSC	Aluminum	630	Fast heat flow, affordable	Polymers, resins
DSC	Platinum	1600	Purity, oxidation resistance	Ceramics, metals
TGA	Aluminum	630	Lightweight, rapid response	Organics, rubbers
TGA	Platinum	1600	No contamination, stable baseline	Inorganic salts, advanced materials

 

What Crucible is Best for High-Temperature Analysis in Electronics?

Electronics often requires thermal tests up to 1600°C or above. The right crucible protects sensitive materials and equipment from damage caused by extreme heat and stress.

Platinum and sapphire crucibles work best here. Both withstand high temperatures and resist oxidation. Platinum is most common for semiconductor, solder, and metal powder analysis. Sapphire is used for the most extreme applications where chemical interaction must be close to zero (sapphire).

Material	Max Temp (°C)	Thermal Shock Resistance	Key Application	Cost Level
Platinum	1600	High	Microchip packaging, soldering	Very high
Sapphire	2000	Excellent	Advanced wafer research	Highest
Alumina ceramic	1750	Medium	Battery and capacitor testing	Moderate

 

Choosing Crucibles for Pharmaceutical Thermal Stability Testing?

Pharmaceutical tests need crucibles that keep samples pure and eliminate risk of trace contamination. Low-quality crucibles often lead to failed batches or regulatory delays.

High-purity aluminum crucibles are the standard in pharmaceutical labs for DSC and TGA because of their clean surface and low reactivity. Platinum and gold crucibles are chosen for extra-sensitive or high-temperature applications. Pick inert crucibles to protect sample safety and compliance (pharmaceutical).

Material	Purity Standard	Common Use	Contamination Risk	Test Example
Aluminum	99.99%	Routine DSC batch tests	Very low	Stability, melting point
Platinum	99.95%	Impurity detection, degradation	Negligible	API endpoint, mass loss
Gold	99.9%	Drug development, trace analytics	Negligible	Polymorph monitoring

 

Which Crucible Materials Work Best for Food Science Thermal Analysis?

Food science focuses on fats, proteins, and sugars that can react with vessels or pick up flavor. Crucibles here must be both clean and non-reactive to keep real results.

High-purity aluminum pans are most widely used because they prevent flavor pickup and reduce sticking. Ceramic pans also have very low reactivity and suit certain niche applications. The ideal choice depends on the sample and analytical goal (food science).

Sample Type	Material	Main Benefit	Contamination Risk	Lab Scenario
Fat content	Aluminum	No taste transfer, fast heating	Very low	Butter, margarine analysis
Sugar/protein	Ceramic	No sticking, stable baseline	Low	Confectionery development
Aroma testing	Aluminum	No odor pickup	Minimal	Flavor R&D
Moisture	Ceramic	Even drying, easy cleanup	Low	Bread shelf-life study
