The Oil Water Separability Tester is manufactured in accordance with ASTM D1401, GB/T 7305, and GB/T 7605 test methods. These standards are widely used to evaluate the demulsibility performance of lubricating oils, particularly turbine oils and other industrial lubricants that may come into contact with water during service.

Demulsibility is a critical performance indicator for lubricating oils. Oils with poor water separation ability can lead to emulsion formation, corrosion, oxidation, and reduced lubrication efficiency in industrial equipment. The test evaluates how quickly and effectively oil can separate from water after controlled mixing at a specified temperature.

The instrument provides precise temperature control, stable stirring speed, and simultaneous multi-sample testing, ensuring reliable and repeatable results for oil analysis laboratories.

It is widely used in petroleum laboratories, lubricant manufacturing plants, power generation facilities, chemical industries, railway maintenance departments, and research institutions.

The ASTM D1401 Water Separability Tester is used for evaluating the oil-water separation characteristics of petroleum products and synthetic fluids.

• Turbine oils
• Hydraulic oils
• Circulating oils
• Industrial lubricating oils
• Synthetic lubricants
• In-service turbine oils

Typical application environments include:

• Petroleum refineries
• Lubricant manufacturing plants
• Power plants and power generation facilities
• Oil analysis laboratories
• Chemical industry laboratories
• Railway maintenance departments
• Research and quality control institutions

The instrument adopts a high-precision temperature control system with fast heating speed and excellent temperature stability, ensuring accurate test conditions required by ASTM D1401 and related standards.

Three test holes allow simultaneous testing of three samples, significantly improving laboratory testing efficiency.

The system uses a high-quality stirring motor with stable rotation speed, low operating noise, long service life, and reliable performance.

Key components such as the heater and stirring paddle are made of corrosion-resistant stainless steel, ensuring durability and long-term stability in laboratory environments.

The instrument is equipped with a high-brightness digital display, allowing operators to easily monitor temperature and operating status during the testing process.

This Oil Water Separability Tester / Demulsibility Tester is designed and manufactured in accordance with the following standards:

• ASTM D1401 – Standard Test Method for Water Separability of Petroleum Oils and Synthetic Fluids
• GB/T 7305 – Petroleum and Synthetic Fluids — Determination of Demulsibility Characteristics
• GB/T 7605 – Determination of Demulsibility of Turbine Oils in Service

These standards are widely used in petroleum and lubricant laboratories for evaluating the demulsibility performance and water separation characteristics of lubricating oils.
