Petroleum Wax Oil Content Tester suitable to determine the oil content in petroleum wax

GD-3554 Petroleum Wax Oil Content Analyzer/Testing Instrument.

The instrument is designed and made as per national standard of People`s Republic of China GB/T3554 Standard Test Method for Oil Content in Petroleum Wax. It is suitable to determine the oil content in petroleum wax, the congealing point of which is higher than 30 ℃ and the oil content of which is not more than 15%.

The method is expressed 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.
Note: 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.

GD-511B Petroleum Products Mechanical Impurity Tester (Weight method).

1. Independent cooling unit with 4 baths. Can do determination for 2 samples by group.
2. The wax melting bath and evaporator are designed as a unibody. The lower part is wax melting bath. Temperature in bath can be controlled and adjustable. The upper part is air bath evaporator. The evaporation temperature is 35 ℃±1 ℃.
3. Digital temperature controller. The temperature control is accurate.
4. The flow rate from evaporator to sample can be detected by glass rotator flowmeter. It can precisely control the flow rate as per requirements of standard. The flowing time can be setted at will within 60min. 
5. Desktop structure and newly design. Reasonable structure and easy to use.
