Gd-3554 ASTM D721 Petroleum Wax Oil Content Tester

GD-3554 ASTM D721 Petroleum Wax Oil Content Tester


I. Introduction
1. GD-3554 ASTM D721 Oil Content in Petroleum Waxes Analyzer 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".
2. GD-3554 ASTM D721 Oil Content in Petroleum Waxes Analyzer is suitable to determine oil content of petroleum wax, the congealing point of which is more than 30 ° C 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.

II. Main Technical Characteristics
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 ° C± 1 ° C.
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.
