Oil-Water Separation Tester

Meet the standard:

ASTM D1401

ASTM D2711

ISO 6614

Product Introduction:

The Oil-Water Separation Tester typically involves mixing a specified volume of the test fluid and water (often distilled water, but sometimes saline or synthetic seawater, depending on the standard) under controlled conditions of temperature and mixing intensity for a set duration. This process creates an emulsion. The resulting mixture is then immediately transferred to a graduated separation vessel, usually a cylinder or funnel, and allowed to stand undisturbed at a controlled temperature. The tester facilitates the observation and recording of the volumes of separated oil, water, and any remaining emulsion layer at specific time intervals (e.g., 5. 10. 20. and 30 minutes).The test results, reported as the volumes of each layer at the specified times or the time to achieve a certain level of separation, indicate how quickly and completely the fluid separates from water. Poor separability can lead to issues like reduced lubrication effectiveness, corrosion, filter clogging, and decreased system efficiency.

The instrument is used for:

Quality control of new lubricating oils, hydraulic fluids, turbine oils, and other industrial fluids.

Monitoring the in-service condition of fluids to assess the impact of aging or contamination on water separability.

Evaluating the performance and optimal dosage of chemical demulsifiers used to break emulsions.

Characterizing the emulsification tendencies of fluids.

Research and development of fluids with improved water separability characteristics.

Product Advantages:

Quantifies Water Separability: Provides objective, numerical data on how well and how quickly a fluid separates from water.

Standard Compliant Testing: Designed to perform tests according to widely accepted international standards like ASTM D1401 and ASTM D2711.

Evaluates Demulsifier Effectiveness: Essential for determining the efficiency of chemical additives designed to break oil-water emulsions.

Relevant to Real-World Applications: Simulates conditions where fluids may encounter water contamination and turbulence.

Helps Predict Fluid Performance: Poor water separability can indicate potential problems in lubrication, filtration, and overall system reliability.

Supports Quality Control and R&D: Crucial for ensuring product quality and developing fluids with desired water separation characteristics.

Relatively Simple and Established Method: The underlying test principle is well-understood and widely applied.

Product Features:

Based on typical Oil-Water Separation Testers, often designed to meet specific standards:

Heated bath or circulating fluid system capable of maintaining the test cylinders or funnels at a precise, controlled temperature (e.g., 54°C or 82°C for ASTM D1401).

Stirring or mixing apparatus capable of mixing the oil and water sample at a standardized speed (e.g., 1500 rpm for ASTM D1401) and duration.10 This may involve an integrated stirring mechanism within the heated bath or a separate mixing device.

Graduated glass cylinders or separation funnels of specified dimensions and volume (e.g., 100 mL graduated cylinders with specific diameter and graduations for ASTM D1401).

Timing device (digital timer or stopwatch) to accurately measure the settling time intervals.

Illumination system (e.g., diffused light source behind the cylinders) to facilitate clear observation and reading of the oil, water, and emulsion layer volumes.
