1. Warning function
Just like the origin of the white coat, it is the representative of cleanliness. Wearing the white coat warns you to keep the laboratory clean and tidy, so as to prevent environmental pollution and potential safety hazards caused by littering drugs.
2. Protect your clothes and skin
It is inevitable that a small amount of drugs will be accidentally spilled during the experiment. Wearing a white coat can protect your expensive clothes and your parents' skin.
3. Timely discover accidental contamination
It is easy to see that the white coat is polluted by the test reagent, and change it in time; If you wear a black experimental suit, it can contain rat blood stains, phenol red of cell culture fluid, various acids and bases, organic solvents, fluorescent dyes, etc., and you can't see any dirt. If you throw away the removed experimental suit when no contamination is found, it is very dangerous for researchers and the surrounding environment.
4. As a colorimetric standard
When chemistry related majors study the physical properties of substances, it may be difficult to distinguish the color of the substance itself or the concentration is too low, so it is easy to distinguish the color of the substance with the white of the white coat as the background.
5. Prevent static electricity
Many of our clothes are fiber fabrics, which are easy to generate static electricity. Many organic reagents and industries cannot have static electricity. Non inferior white coats can prevent static electricity to a certain extent.
