Automatic freezing point determination of glacial acetic acid solution
According to The Chinese Pharmacopoeia 2015 edition, the freezing point of glacial acetic acid (general rule 0613) is not less than 14.8°C, and this product is a colorless clear liquid or colorless crystalline block; It has a strong odor. This product and water, ethanol, glycerin or most volatile oil, fat oil can be arbitrarily mixed. The determination method of glacial acetic acid is determined in accordance with the General rule 0613 method in Chinese Pharmacopoeia 2015 edition, and ST203B automatic drug freezing point tester is fully in line with this method. According to the glacial acetic acid sample provided by the customer, the freezing point of glacial acetic acid measured by ST203B automatic drug freezing point tester was 14.9%.
