Determination of the dynamic shear viscosity using a rotary rheometer. The displayed price includes a shear rate ramp test at a specified temperature. Please specify the following upon ordering the test: desired testing temperature (max. 200 °C), desired shear rate range (from 0,1 s^-1 to 100 s^-1). The set-up configuration of the rheometer can be chosen based on the sample type (the most common options are parallel plate and cone-and-plate). Do not hesitate to ask for a quote for a custom viscosity testing program. For example: temperatures from -20 to 600 °C, and shear rate ranges from 0,01 to 1,000 s^-1 are possible, as well as rotational and oscillatory measurements, time and temperature sweeps, etc.

Solution viscosity is determined according to the ISO 1628 standard using a capillary viscometer. The method measures the resistance of a polymer solution to flow by recording the time it takes for a specific volume of liquid to pass through a capillary with known geometry. Temperatures: 25 - 135 °C

Kinematic viscosity measurement according to DIN 51659-2 at 40 °C and 100 °C using a Stabinger viscometer. Kinematic viscosity is calculated from the dynamic viscosity and density of the analyzed oil. The analysis is suitable for oils that fall within the following viscosity ranges: Viscosity range at 40 °C: approx. 4–1,000 mm²/s, Viscosity range at 100 °C: approx. 2–100 mm²/s.
