Physical characteristics

Thickness: 1.0 $\pm$ 0.1 $mm$
Diameter: 30.0 $mm$
Volume: 700.0 $mm^3$
Mass: 0.4707 $\pm$ 0.0901 $g$
Surface roughness: low
Substrate material: aluminum anodized black
Substrate comments: depth 1mm
Comments: Mass of dry sample = 0.46g

Sample environment: Temperature

Temperature: 243.1 $\pm$ 0.5 $K$
Time at T: 0.0 $min$
Temperature max: 443.0 $K$
Time at Tmax: 600.0 $min$
Comments: Sample temperature error is mostly due to possible vertical temperature gradient in the sample. Temperature reading accuracy and stability is 0.1K - Small pressure applied during sample flattening with a spatula
