— Accurately Assess Oil-Water Separation Performance to Safeguard Lubrication Quality
In actual service, when lubricating oils come into contact with water, they may form emulsions that severely impair lubrication effectiveness and even cause equipment failure. The DFYF-107 Lubricating Oil Demulsibility Tester is strictly designed and manufactured according to the GB/T 8022 standard. It is specifically used to determine the demulsibility performance of medium and high viscosity lubricating oils – i.e., the ability of the oil to separate from water quickly and completely. This tester is widely used in lubricant R&D, production quality control, and third-party testing laboratories.
Core Advantages
✅ Designed for Medium & High Viscosity Lubricating Oils
Complies with the GB/T 8022 method, accurately simulating the emulsification and separation process when lubricating oils are mixed with water during use. Results are reliable and realistic.
✅ Two-Hole Separatory Funnel Design – Increases Testing Efficiency
Equipped with 2 test positions, allowing parallel testing of two samples simultaneously, saving time and facilitating comparative analysis.
✅ Wide, Precise Temperature Control
Control range: ambient ~ 99.9°C
Control accuracy: ±1°C
Digital temperature controller + solid-state relay + heater combination provides automatic constant temperature with uniform and stable bath conditions.
✅ Powerful Adjustable Stirring System
Stirring motor power: 92W
Speed: 0–6000 r/min, continuously adjustable
The stirring unit can be adjusted vertically, horizontally, and in position to suit different separatory funnel sizes, ensuring consistent stirring results.
✅ Easy Operation & Clear Display
Digital temperature controller allows simple setting and reading. The solid-state relay provides contactless, long-life temperature control. The entire unit operates reliably.
