Micro-scale experiments use much smaller amounts of chemicals and equipment than traditional macro-scale experiments. This reduces costs, waste, pollution, and safety risks. Some key advantages of micro-scale experiments are that they are more cost-effective due to smaller apparatus, more environmentally friendly due to less chemical waste, and suitable for both organic and inorganic experiments as the set-ups can be built easily by students. Making the transition to micro-scale experiments can make chemistry labs more sustainable by minimizing the use of chemicals and reducing pollution.
