RRR: Reduce - Reuse - Recycle
Demonstration of experiments in large containers
("macro-scale") are very impressive but they waste resources and money leaving
unnecessary waste to disposed.
Microscale experimentation means "reduction of chemical use to the minimum level at which experiments can be effectively performed".
For liquids these are volumes between 10 µL (small drop) and 5 mL, for gases up to 50 mL.
