Tag: EMS Viscometer

Breakthrough technology in viscosity measurement

N-Wissen GmbH introduces the world’s first electromagnetic viscometer EMS-1000S with rheological properties for viscosity measurement of micro samples up to 90μL.

The  EMS viscometer is a new type innovative small volume viscometer that changed the common sense of viscosity measurement. With simple operation, this instrument enables quick and precise measuring of small amount of the sealed sample. Disposable containers also free the user from cleaning sample container after measurements.

Main Features:

    1. Small sample volumes required: 300μL (standard) or 90μL (optionally)
    2. Covers very wide viscosity range: 0.1 to 1 000 000 mPa·s
    3. Low viscosity measurement at constant or changed shear rates possible
    4. Integrated temperature control unit allows to set and reach quicly the temperature within range of 0℃ to 200℃, ±1℃
    5. Sealed Containers: toxic, volatile or anaerobic samples can be measured
    6. Disposable Containers: no need to clean the sampel containers after measurement. During measurement, the samples are not contaminated.
    7. Short Measuring Time: only 1 second is required to measure samples with a viscosity below 100 mPa·s and approx. 1 minute is required to measure samples with a viscosity of 10 000 mPa·s
    8. 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.
    9. Continuous measurement: by seating the measurement time, shear rate and temperature you can observe the viscosity changes of the same sample.
    10. Reliable measurement by viewing the status of sample with the integrated camera. You can check the status of the sample in real time with the built-in camera in the main unit.

The specially coated accessories offered exclusively by N-Wissen GmbH make the instrument to be suitable for viscoelastic materials like polymers, protein solutions, suspension, emulsions, etc.

The world’s first Electromagnetically Spinning Viscometer

N-Wissen GmbH presents the world’s first Electromagnetically Spinning Viscometer / Rheometer for Small, Sticky and Precious Samples.

ems10001

The measuring principle is impressively simple and very powerful:
*  Wide measuring range 0.1 … 1,000,000 mPa∙s for many applications
* Automatically evaluate the temperature dependency of the viscosity in the range of 0 … 200°C within a very short time
* Captures the whole measurement with its built-in video camera
* Excellent repeatability of the measured values
* Disposable measuring cell – no cleaning required
* Requires only very small sample volumes (300 µl)
* Capable of performing determinations of the rheological behaviour of liquids by determining the shear rate dependency of the viscosity
* Provides a better absolute accuracy and repeatability of the results than classical Rotational Viscometers.
