How to test electromagnetic rotational viscometer? -Electromagnetic Rotational Viscometer EMS-1000S

The EMS-1000S electromagnetic force rotational viscometer is a new generation viscometer developed in collaboration between KEM Corporation of Kyoto Electronics and the University of Tokyo in Japan. It is also the world's first to measure liquid viscosity using the principle of electromagnetic force rotation. The viscosity measurement range is 0.1-100000mPa · s, the temperature setting range is 0-200 ℃, and the measurement time for viscosity below 100mPa · s is only 1 second. The flow curve of the sample can be obtained by changing the speed. The required sample quantity is only 300 μ L. It can be used as a disposable container without cleaning and is easy to operate with a computer and software.

The main features of the electromagnetic force rotating ball viscometer EMS-1000S are:

1. Large temperature range: 0-200 ° C, ± 0.1 ° C, within 10 minutes (25 ° C → 200 ° C).
2. Wide measurement range: 0.1-100000mPa · s (when using a Φ 2mm sphere).
3. Fast measurement speed: less than 100mPa · s takes about 1 second, 10000mPa · s takes about 1 minute.
4. Evaluable flowability: Shear rate ranging from 0.01 to 150 s-1, flow curve evaluated by rotational speed.
5. Extremely small sample size: Standard 300 μ L, optional 90 μ L sample container for viscosity testing.
6. Good airtightness: Sealed test tubes prevent sample evaporation and errors. The sample can be recycled and reused.
7. The operation is very simple: put the sample and sphere into a test tube, and the test tube can be placed inside the instrument for testing.
8. No need for cleaning after testing: Use inexpensive and disposable sample tubes and spheres.
