Sample Description

Sample Requirements:
• Solid Samples: - 60mm x 12mm x 5mm (Fixed).
• Sample should not be volatile, must have no chemical incompatibility with Clamp material.
• Only samples with known decomposition temperature can be tested (TGA recommended as a preliminary test/screening method to validate sample viability for DSC).
• Safety data sheets for sample materials are required.
