The Electromagnetically Spinning Viscometer (EMS viscometer) is a new type of viscometer that:

​

• is suitable for measuring fluids with viscosities in the range of 0.1 to 1,000,000 mPa·s

• can automatically evaluate the temperature dependency of viscosity in the range of 0 to 200°C in a very short time

• can determine the rheological behaviour of liquids by performing shear rate dependency of viscosity analysis

• provides a better absolute accuracy and repeatability of results than conventional rotational viscometers

​

The EMS Viscometer measures viscosity through the observation of a spherical probe that is spun in a liquid sample by electromagnetic interactions. 

​

The EMS Viscometer has a number of advantages over other rotational viscometers:

​​

• Samples are measured using cost-effective, disposable tubes and probes, meaning contact-free measurement, zero clean up and no risk of equipment failure when using samples that harden during measurement

• The autoclavable tube suits samples that need to be kept sterile and can be hermetically sealed for measurement under anaerobic conditions

• The EMS-1000S can measure samples as low as 90µL in volume, ideal for the analysis and reuse of scarce and expensive samples
