Stanhope-Seta released a device to determine a lubricants ability to separate from water. The Herschel Emulsifier is a benchtop instrument that tests water separation from oils and synthetic fluids. Its four individual stirrers with automatic raising and lowering allow for simultaneous or individual tests. Test cylinders are located in a temperature controlled bath with an adjustable set point of either 54 or 82 degrees Celsius, in accordance with ASTM and ISO test methods, the company adds. The products display gives audio and visual reminders at each recording interval, and its safety features include obstruction overrides, a sensor to alert of overheating and low liquid levels, and an emergency button to stop the test.
