SD7305 Petroleum Demulsification Tester

2025-08-25

The ability index of petroleum and synthetic liquids to separate under specified conditions after being mixed with water is a key parameter for measuring their anti-emulsification performance. The shorter the demulsification time, the better the performance is usually indicated. In fields such as petroleum and power, if oil products have poor anti-emulsification performance, they are prone to form oil-water emulsions, which may affect the lubrication effect of equipment and cause component corrosion. Therefore, precise measurement is required.

The SD7305 petroleum demulsification tester adopts a small cylinder desktop structure, which is compact in size and easy to operate. The motor inside the bath automatically stirring to ensure uniform temperature. It supports placing two samples simultaneously for sequential testing. The stirring shaft has good concentricity, without any shaking or tube collision. This instrument is designed and manufactured in accordance with the standards of GB/T7305 and GB/T7605-2008, equivalent to the ASTMD1401 standard. It can accurately determine the ability of petroleum and synthetic liquids to separate from water and is widely used in the fields of petroleum, power, chemical engineering, as well as in colleges and universities and research institutes.
