The difference between 95% alcohol and 75% alcohol is as follows:
1, the use of different
Alcohol content of 75% is mostly used for sterilization and disinfection, while the alcohol content of 95% is used as a wipe UV lamp.
2, different ability to disinfect
Alcohol content of 95% can not be bacterial disinfection, while the alcohol content of 75% can be bacterial disinfection. High concentration of alcohol sterilization effect is poor, 70-75% alcohol sterilization effect is best.
3, the concentration of different
Alcohol content of 95% concentration is higher, while the alcohol content of 75% concentration is low, 75% alcohol needs to be diluted with 95% alcohol operation to get.
What is the use of 95-degree alcohol
1, 95% alcohol used as fuel. For example, scientific research departments, medical units need to use this concentrated alcohol as alcohol furnace, alcohol lamp fuel, heating related chemical reagents for scientific research. It can also use alcohol flame to sterilize the surface of small medical equipment.
2, can be diluted into 75% alcohol, used as a medical skin surface wipe disinfection, or cotton swabs to remove the body surface iodine preparation. Note that patients with skin allergies need to be used with caution.
3, it is applied to the legal sector of ethanol gasoline production. 95% alcohol concentration is high, pay attention to the open flame in the operation process to prevent fire.
Alcohol's scientific name is ethanol, which has a great penetrating ability to drill into the bacteria, so that the bacterial proteins coagulate, thus killing the bacteria. And 95% alcohol concentration is very large, can be bacteria surface protein membrane quickly coagulation, the result is the formation of a layer of hard film, this layer of hard film on the bacteria has a protective effect, preventing the further penetration of alcohol, so the concentrated alcohol instead of as good as dilute alcohol.
Dilute alcohol is not eager to make the bacterial surface protein coagulation, but penetrate into the bacterial body, and then the whole bacterial body protein coagulation, so as to achieve the purpose of sterilization.
