Vane Spindles

Precision Measurement for Paste-Like Materials, Gels, and Fluids

Vane Spindles are the ideal solution for measuring the viscosity of paste-like materials, gels, and fluids where suspended solids tend to migrate away from the measurement surface of standard spindles. These spindles are engineered to minimize sample disruption during immersion and maintain particle suspension throughout the testing cycle.

Minimal Sample Disruption: The design ensures minimal disturbance to the sample during spindle immersion, preserving the integrity of the test.
Keeps Particles in Suspension: During the testing cycle, vane spindles keep particles evenly distributed within the sample, leading to more accurate viscosity measurements.
Complete Flow Curve Analysis: When used with compatible software, vane spindles allow for comprehensive flow curve analysis, providing deeper insights into the material’s rheological properties.
Yield Behavior Information: At low rotational speeds, vane spindles offer valuable data on the yield behavior of the test material, essential for characterizing thixotropic substances.
Industry-Standard Ratios: Follows industry recommendations on length-to-diameter ratios, ensuring precise and consistent measurements.
Versatile Range Capability: The standard 3-piece spindle set (V-71, V-72, V-73) covers a wide range of viscosities. Optional V-74 and V-75 spindles extend this range further, allowing for immersion in smaller sample containers.

Magnetic Spindle Coupling Option

The Vane Spindles are also available with a Magnetic Spindle Coupling Option. This option enables quick and easy spindle attachment and removal, which can help prevent damage from frequent spindle changes or multiple users. Existing Vane Spindles can also be retrofitted with a special coupling adapter for use with instruments equipped with magnetic spindle coupling systems.
