Spinning Viscometer

A new approach for viscosity measurements. The world’s first!
The EMS Viscometer measures the viscosity of liquid through observation of the rotation of a sphere which is driven by electromagnetic interaction. This new contact free viscometer was developed in collaboration with Institute of Industrial Science, the University of Tokyo within the framework of the Japan Science and Technology Agency (JST).

Features
Wide Temperature Range
Temperature range : 0 to 200?
Temperature stability : ±0.1 ?
Heating rate : Within 10 minutes(25? to 200?)

Wide Measuring Range
Viscosity range : 0.1 to 100,000 mPa?s
The standard measuring cell covers the entire viscosity range – no need to use different types of rotors.

Short Measuring Time
Only 1 second is required to measure samples with a viscosity below 100 mPa?s.
Approx. 1 minute is required to measure samples with a viscosity of 10,000 mPa?s.

Rheological Properties
Shear rate : 0.01 to 150s-1 (depending on the sample’s viscosity)
The shear rate can be varied by changing the rotational speed of motor, flow curves can be determined.

Suitable for Very Small Samples
Sample volume required : 300?L

Measurements of samples which are available in very small quantities can now be performed. During measurement, the samples are not contaminated.
Samples can be used for other purposes after measurement.

Versatile Measuring Container
No cleaning required.
Measurements are performed in a disposable sample container.
No cleaning required – no cross contamination.

Autoclave sterilization
Ideal for samples which must be measured in a sterile environment such as proteins.

Suitable for measurements under anaerobic conditions
Sealed sample container. This allows to perform measurements in an inert-gas atmosphere.
