Understanding TGA (Thermogravimetric Analysis)

Thermogravimetric Analysis (TGA) is a thermal analysis technique that measures the mass change of a sample as a function of temperature or time. These alumina crucibles provide an inert environment for accurate mass measurements during thermal decomposition, oxidation, and other thermal processes.

Why Alumina Crucibles for TGA?

• Chemical Inertness: Alumina does not react with most samples
• High Temperature Stability: Maintains integrity at extreme temperatures
• Low Thermal Expansion: Minimizes measurement errors
• Excellent Thermal Conductivity: Ensures uniform sample heating

Available Size Options

Applications

• Material Characterization: Thermal stability studies
• Decomposition Analysis: Reaction kinetics research
• Purity Assessment: Volatile content determination
• Quality Control: Production monitoring
• Research & Development: Material development

Technical Advantages

Superior Material Properties

• 99.7% alumina purity for minimal interference
• Low porosity design prevents sample contamination

Usage Guidelines

Sample Preparation

For optimal results, ensure samples are properly prepared and do not exceed the crucible's recommended fill level (typically 2/3 capacity).

Cleaning & Maintenance

• Clean crucibles before first use
• Use appropriate solvents for sample residue removal
• Inspect for cracks or damage before each use
• Store in clean, dry environment

Lid Options

Important Note: This crucible does not include a lid. If your analysis requires a covered environment, please add the appropriate lid to your cart separately. Contact our technical team for lid compatibility information.

Quality Assurance

• Manufactured to exact OEM specifications
• Each batch undergoes quality testing
• Dimensional accuracy guaranteed
• Material purity certified

Frequently Asked Questions

Q: What's the difference between TGA and DSC crucibles?

A: TGA crucibles are typically open and designed for mass change measurements, while DSC crucibles often have lids and focus on heat flow measurements. This crucible is optimized for TGA applications.

Q: Can I use these crucibles for other thermal analysis techniques?

A: While designed for TGA, these crucibles can be used for other high-temperature applications, but always verify compatibility with your specific instrument and analysis requirements.

Q: How many times can I reuse these crucibles?

A: With proper care and cleaning, these crucibles can be reused many times. Replace when you notice damage, contamination, or dimensional changes.
