DSHD-3554 Petroleum Wax Oil Content Tester

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 the oil content of petroleum wax, the congealing point of which is higher than 30 ℃ and the oil content of which is not more than 15%. Specific operation is as follows: Solve sample in the methyl ethyl ketone and cool it to -32 ℃ to separate wax out. Filter it and evaporate methyl ethyl ketone in the filtering liquid. Weigh the residue and calculate the oil content in the wax. It is worth noting that For some wax having oil content higher than 5%, if the oil could not be completed dissolved in the methyl ethyl ketone, please don't use this instrument.
