1. Nitrile-butadiene rubber gloves can effectively protect acid and alkali, but they have general protection against organic solvents and are moderately priced. They are the first choice for general laboratories.

2. PVA protective gloves can effectively protect most chemicals, but their flexibility is poor and expensive.
3. When using a variety of chemicals, consider the hazards of the chemicals and choose the highest level of protection according to the characteristics of the glove material. You can also consider wearing double-layer (different materials) gloves for protection.
4. In addition to paying attention to the material and type, you also need to pay attention to the size. If the gloves are too tight, it will be uncomfortable to wear and the protective gloves will be easily damaged; if they are too loose, they will be inflexible and easy to fall off, resulting in protection failure.
5. In short, there is no "universal" gloves. It is the best policy to choose the correct gloves according to the chemicals in contact with them.
