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.

VOC Emission Test Chambers

Volatile organic compounds (VOCs) are compounds that under normal conditions are emitted as gases from certain solids or liquids. VOCs cover a wide range of solvent using activities, e.g. printing, houshold surface cleaning, vehicle coating, furniture production, dry cleaning and manufacture of footwear and pharmaceutical products. Some of VOCs may have short- and long-term adverse health effects, thus it is very important to measure and control quantity of VOCs.

N-Wissen GmbH offers wide range of chambers for VOC and formaldehyde emission test according to ISO 16000-9, ASTM D6007-02, ASTM D5116, ASTM D6330, ASTM D6670-01, ASTM D7706-11, ASTM E1333, UNI CEN/TS 16516, GEV Testing Methods, EN 13419-1 and UNI 717-1 international standards.

All chambers can be designed and manufactured according to customer requirements.

Ozone Resistant Test Chamber

In operation the rubber materials deteriorate when exposed to ozone. Thus it is vey important to have test methods in which simple, accelerated time/exposure, comparisons of the material’s ability to resist cracking caused by ozone exposure can be empirically evaluated.

N-Wissen GmbH is glad to present the new Ozone Resistant Chamber OZT-QL-15040 for testing rubber materials and components according to the following standards:

  • ASTM D1149 – 18 “Standard Test Methods for Rubber Deterioration – Cracking in an Ozone Controlled Environment”
  • ISO 1431-3:2017 “Rubber, vulcanized or thermoplastic – Resistance to ozone cracking”
