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.

Taking the Karl Fischer Moisture Titrator into a new stage

Hybrid Karl Fischer Moisture Titrator MKH-700 has the world’s first & convenient functions equipped such as high-speed & high-precision measurement by “Hybrid titration method” which uses both “Volumetric titration method” and “Coulometric titration method”, and “Electrolytic Factor Measurement System” which does not require pure water for factor determination.
mkh7001
Karl Fischer Moisture Titrator which is on the market is necessary to adjust the sample amount when carrying out the measurement.
“Hybrid titration method” automatically switches between the parallel measurement by “Volumetric titration method” and “Coulometric titration method” by monitoring moisture content in titration cell with high-speed & high-precision measurement, therefore can measure without adjusting the sample amount.

With just pressing one button, the “Electrolytic Factor Measurement System” automatically performs the factor determination of Karl Fischer reagent, and save the time & work without using pure water.
