Made of glass, good thermal stability, chemical stability, mechanical properties,high transparency.
Standardized glass tubes used to fill with standard solution colors for visual color comparison with similar tubes containing solution samples.
In contrast, two colorimetric tubes were placed in front of white paper of the same degree of illumination, and the color difference was observed with the naked eye.
