Herschel Emulsifier

Part Number 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 motorised 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 test and provides automated sequencing with an audible and visual reminder at each recording interval.


Operator Safety
- Obstruction override if paddles are placed under any resistant load
- Duplex protective viewing glass
- Automatic high temperature cut out
- Overflow prevention
- Automatic low-level liquid trip
- Abort button for emergency all stop

Ease of Use
- Fully automated paddle movement with motorised raising and lowering
- Easy sample handling without removing the stirrer paddle
- Self-centering collet to ensure concentricity within 1mm
- Positioning within 6mm from the bottom of the cylinder automatically achieved
- Large LCD touch screen display

Precision and Accuracy
- Non-reflective enhanced LED lighting for improved measurement precision
- Post stirring, intermediate scraping position ensure accurate readings
- Guaranteed paddle rotation speed, regardless of viscosity
- Large viewing window

Enhanced Test Throughout
- 4 independently controlled test stations reduce waiting time
- Rapid bath heat up time
