How to choose the right viscometer rotor?

The viscometer rotor is an important part used to measure the viscosity of liquids, and its selection has a great influence on the accuracy and reliability of the measurement results. The following are the main points and precautions for viscometer rotor selection:

Measuring range: The choice of the viscometer rotor should be determined according to the viscosity range of the liquid to be measured. The measuring range of different spindles is different, usually in units of dynamic viscosity. When selecting a spindle, it should be ensured that its measuring range can cover the viscosity range of the liquid to be measured.

Measurement Accuracy: The size and shape of the rotor also affects the measurement accuracy of the viscometer. In general, the larger the rotor size, the more accurate the measurement results. However, larger rotors may not be able to fit into smaller vessels or pipes, so it is necessary to choose a suitable rotor based on actual needs.

Speed: The choice of viscometer spindle should consider its recommended speed range. The rotational speed of the rotor has a major influence on the precision and accuracy of the measurement results. When selecting a spindle, it should be ensured that the speed of the chosen spindle is compatible with the viscometer equipment.

Adaptability: Different viscometer rotors are suitable for different types of liquids. For example, some liquids may generate air bubbles or foam when measuring, which may affect the measurement results. Therefore, it is necessary to select a rotor suitable for a specific liquid type to obtain more accurate measurement results.

Cleaning and Maintenance: When using a viscometer spindle, care needs to be taken to keep it clean and maintained to ensure its accuracy and reliability. Especially after the rotor has been used, it should be cleaned and stored properly to avoid contamination or damage.

In short, when selecting a viscometer rotor, it is necessary to fully consider the actual needs, select the applicable rotor, and keep it clean and maintained to ensure the accuracy and reliability of the measurement results.
