Open-source colorimeter assembled from laser-cut plates and plug-in circuits
Colorimetric analysis is a fundamental technique for quantifying the concentration of a substance in solution. It is frequently used in primary and secondary education to enhance students’ interest in chemistry, biology, life science, and environmental problems. The structure of the colorimeter is q...
