Rotating Spindle ViscoMeter

The rotor rotational viscometer drives a rotor to rotate within the sample via a motor and measures the viscous resistance experienced by the rotor. This resistance is proportional to the viscosity of the sample, and the instrument directly displays the viscosity value. It is used for detecting the viscosity of fluids such as coatings and inks, guiding adjustments in production processes.
Selection
Consider whether the measurement range and accuracy meet the sample characteristics. The sample volume determines the rotor size, and temperature control functionality is suitable for constant-temperature testing scenarios. Ease of cleaning affects usage efficiency, and rotor material must resist sample corrosion. The operation interface should be simple and readable.

Guide to Selecting a Laboratory Rotational Viscometer for Coatings Development
This article introduces how to select a laboratory rotational viscometer in coatings research and development. It first explains the principle of rotational viscometers measuring viscosity based on shear resistance, and then points out that key parameters to consider during selection include measurement range, shear rate, temperature control, and rotor configuration.
Comparison of Rotational Viscometer and Capillary Rheometer in Testing the Flowability of Resin Processing
The rotational viscometer measures torque via rotor rotation, making it suitable for testing the static or low-shear fluidity of resins under low shear rates, with simple and quick operation. The capillary rheometer, on the other hand, forces samples through a capillary to simulate high-shear processing, providing flow data closer to actual production conditions, but it is more complex and time-consuming to operate.
Rotational Viscometer Measures Viscosity and Processability of Resin Melts
A rotational viscometer calculates viscosity by measuring the torque experienced by a rotor as it rotates in the resin melt, thereby helping to understand the material's processing properties.
Rotational Viscometer for Measuring and Controlling the Application Viscosity of Coatings
A rotational viscometer is a commonly used tool for controlling the viscosity of coatings during application, as it measures the torque generated by a rotor rotating in a fluid to calculate viscosity.
Method for measuring ink viscosity with a rotational viscometer
A rotational viscometer measures viscosity by detecting the torque experienced by the rotor as it rotates in the ink, with the calculation formula being η = K × (T/ω). Before measurement, it is necessary to select an appropriate rotor, control the temperature, and calibrate the instrument.
The rotational viscometer reads the viscosity of ink.
A rotational viscometer measures viscosity by generating torque through a rotor rotating in the ink, aiding in the analysis of the ink's flow characteristics. The thickness or thinness of the ink affects printing quality, and both excessive thickness and excessive thinness can lead to issues.
