More convenient! Easier to use!

EMS viscometer is a new type innovative viscometer that changed the common sense of viscosity measurement in the world for the first time.
By applying torque to the spherical probe in the sample remotely from the outside of the sample container using the force of the magnetic field, we succeeded in completely separating the sample from the device.
We have prepared a state-of-the-art viscosity analytical technology with easy-to-use software and a spherical probe that can be selected according to sample properties, enabling application in a wide field. It is also compatible with small amount, low viscosity measurement which was difficult to measure up to now.
This product adopts part of development results obtained as the framework of JST Japan Science and Technology Agency.

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 100,000mPa・s(applied φ2.0mm spherical probe)

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 100mPa・s.
Approx. 1 minute is required to measure samples with a viscosity of 10,000mPa・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 : 90μL

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.
Required amount of sample is 300μL in standard specification. By using an optional small volume container, it is possible to measure with a minimum sample volume of 90μL.

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.

(* 1) Repeatability is indicated by the relative standard deviation when the viscosity range is 10 to 1000mPa·s and the measurement is carried out 5 times continuously without changing the equipment conditions (sample, spherical probe and container combination).

(* 2) When setting the preset temperature below room temperature, please prepare dry air for dew condensation prevention. Also, when setting the temperature below 10°C, keep the ambient temperature below 20°C.
