Sample Name (mandatory field)
Enter the sample name.
NOTE: You will not be able to change the name of the sample once the sample is created.
2. ENVIRONMENT SETTINGS
Temperature (°C)
Sample temperature range: 2°C to 40°C. It is recommended to use Room Temperature.
Use water viscosity (mPa.s)
Check box. If your sample is an aqueous medium, check the Use Water Viscosity box. The viscosity will automatically be adjusted
with temperature1. This box is checked by default.
Viscosity (mPa.s)
Viscosity of the sample. If the viscosity of your sample is different from the viscosity of pure water, uncheck the Use Water
Viscosity box, and manually enter the viscosity of your sample.
Range: 0.3 to 10 (mPa.s).
To guarantee the quality of the results delivered, the temperature and the viscosity of the sample must be adjusted according to the
experimental conditions NOTE: You will not be able to change the sample temperature and viscosity once the sample is created.
