To create physiological saline, people dissolve 9g of pure salt with 1 liter of distilled water. Although the ingredients and preparation are simple, in order to create a standard physiological saline product, it is necessary to ensure a lot of factors from salt raw materials to ensure cleanliness, no impurities, no contamination, no water. Distillation must meet standards, preparation equipment must be clean, the weighing process must be standard to ensure the correct concentration of salt water, the preparation area must be sterile,...
