Latex gloves have different grades. How do you differentiate the grades of latex gloves? The main difference (not the only difference) of gloves of different grades is the number of particles. The higher the number of gloves, the lower the class. ), professional testing methods may not be available in some units, can use a simple method: do not take each of the different grades of gloves samples, slice into 1-2cm square pieces, do not leave a clean beaker, add the same amount of pure water (Without conditions, you can use tap water) about 100ml, mix well with a glass rod, and can shake for 1-2h under certain conditions.
Visually, if there are more impurities in the pure water, the level is low, and the relatively small amount of impurities means that the level is higher. This method can be different from class1000, but the difference between class100 and class10 does not come out, and professional methods are needed.
