The instrument is designed and made as per the National Standard of People’s Republic of China GB/T3554 “Test Methods for Oil Content of Petroleum Wax”. It is suitable to determine oil content of petroleum wax, the congealing point of which is more than 30 ℃ and the oil content of which is less than 15%.
Note: For some petroleum wax having oil content more than 5%, if the oil could not be completely dissolved in methyl ethyl ketone (MEK) and the mixture is separated into two layers, this method is not applicable.
