How to blend medical alcohol?

Generally, the mixing ratio of disinfection alcohol and water is 3: 1. If you want to make 100ml disinfectant alcohol, you need 25ml distilled water and 75ml alcohol. If anhydrous alcohol is used, the purity ratio is wrong, but it will not affect the use effect. It is recommended to choose distilled water or pure water when diluting alcohol.

Generally speaking, sterilized alcohol refers to 75% alcohol, so the ratio of alcohol to water in 75% alcohol should be 3: 1, that is, after adding 1 part water, 3 parts of alcohol must be added to make sterilized alcohol. If you want to prepare 100ml sterile alcohol solution, you need 25ml distilled water and 75ml alcohol.

At present, the main disinfectant alcohol in the market is 75% alcohol, but it is wrong to mix it with anhydrous alcohol, because the purity of alcohol in anhydrous alcohol is 99.5%, so the concentration of disinfectant alcohol made of anhydrous alcohol is low, but generally it will not affect the use effect.

Generally, it is best to use distilled water to prepare alcohol solution. If there is no distilled water, you can use pure water or mineral water instead. At least there are no impurities in the water that can pollute alcohol. However, if alcohol is diluted with tap water, it will affect the purity of alcohol and the use effect of alcohol.
