Aluminum Crucible with Lid for DSC/TGA (eg: TA, Mettler), 50 pcs/pack, CDSCTGAACL

A Mettler Toledo Aluminum Crucible with Lid is a precision-engineered sample container designed specifically for Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) instruments. Fabricated from high-purity aluminum (typically ~99.9%), these crucibles serve as the inert thermal interface between the sample and the micro-furnace sensor, ensuring highly accurate calorimetric and gravimetric data.

The critical features of the aluminum crucible are: (1) Exceptional Thermal Conductivity: Aluminum provides rapid, uniform heat transfer from the furnace to the test sample, eliminating thermal gradients and ensuring sharp, well-defined enthalpy peaks and glass transition (Tg) inflections. (2) Temperature Operational Limit: Because aluminum melts at approximately 660℃, aluminum crucibles are strictly limited to low-to-medium temperature analyses, with a maximum safe operating ceiling of 600℃ to 640℃. (3) Chemical Inertness: Pure aluminum forms a stable, protective native oxide layer (Al2O3) that resists reaction with most organic polymers, pharmaceuticals, waxes, and non-corrosive battery materials (such as solid polymer electrolytes, binders, and certain carbon composites) below its melting point.
