Herschel Emulsifier – 96700-2
The Herschel Emulsifier is a compact and efficient benchtop instrument designed to measure the ability of petroleum oils and synthetic fluids to separate from water.
The instrument incorporates 4 test stirrers, with independent control and motorized raising and lowering. Samples can be tested simultaneously or individually to suit laboratory requirements.
Test cylinders are located in a temperature-controlled bath with an adjustable set point of either 54 or 82 °C, in accordance with ASTM and ISO test methods. A large LCD touch screen display is used to initiate a test and provides automated sequencing with an audible and visual reminder at each recording interval.
Methods: ASTM D1401, IP 412, ISO 6614
