Purified water used in the laboratory as a basis to create solutions or making dilutions. It contains no interfering substances. Laboratories utilize purified water for the purposes of experiments. However, unclean water can wreak havoc in the lab, so the quality of the water is vital for the success of the experimentation. The processes of distillation and deionization are commonly used for this process since they help eliminate the molecules and atoms in the water, including organic substances.
