The water used in the laboratory is generally: ordinary tap water, distilled water, and Ultrapure water. The construction of water supply should consider safety, science, and applicability. When walking into the water, you need to select the materials based on detailed experiments, which are the water pipes and joints. We also need to consider the separation of water and electricity, the environment around the water pipes, the direction of the waterways, and so on.

The drainage of laboratories is generally quite troublesome, as there are significant differences in the laboratory's drainage standards and actual national conditions, as well as detailed laboratory or laboratory building environments. The wastewater in the laboratory can generally be divided into polluted water and low pollution water. Low pollution water generally refers to the condensed circulating water of Mo equipment and the wastewater from washing Mo containers. There are many types of polluted water, including corrosive water such as acid and alkali corrosive water, organic corrosive water, inorganic contaminated water, and heavy metal contaminated water.

The electricity consumption in the circuit problem laboratory is a very important issue, including weak electricity, lighting electricity, safety electricity, and testing equipment electricity. During this period, the primary focus is on the use of electricity for laboratory instruments and equipment, especially for some precision instruments. The principles of these instruments and equipment are mostly based on the action and reaction of the Lorentz force principle, which is controlled by slight changes in current.

The problems we need to deal with when using electricity for laboratory instruments and equipment are to manipulate and reduce the fluctuation of current, reduce or stabilize the value of harmonic changes, reduce or reduce the disturbance of magnetic fields, and so on. If problems with electricity cannot be solved, severe ones can lead to disasters, while general ones can result in damage to instruments, inaccurate or unstable testing, reduced service life of instruments, and so on.
