Students see immediate results and check results by repeating the procedure more than once in one lab period. These experiments also require minute amounts of materials. They use drops instead of milliliters of materials, milligrams vs. grams of chemicals. Storage of a solution is cut down to a minimum and the cost of doing the experiment is cut about 90 percent. The microscale equipment is very inexpensive and reusable.
Microscale labs allow safety concerns to be cut to a minimum.
The majority of the equipment is plastic so the breakage factor is virtually eliminated. A very small quantity of reagent is used so spillage is minimal. Experiments, such as the generation of hydrogen is generated eliminating the danger of fire or explosion. Gases, such as chlorine, can be safely generated by microscale. Because of the toxic natures of this gas, it's generation has been eliminated at the macroscale level.
