IKA Holder MV 1 Mount for measuring vessels, 0020019816

Kinematic fixation and axial alignment

In instrumental rheology and the high-precision torque measurement of structurally viscous fluids, the mechanical stability of the measuring vessel is a fundamental metrological requirement. The IKA Holder MV 1 acts as a highly rigid mechanical bridge element for securing specific measuring vessels (MV) within the process setup. When agitators or measuring bodies rotate in highly viscous matrices, enormous torsional forces arise which tend to force the entire vessel into solid-body rotation. The MV 1 holder completely blocks this torque through a rigid form-fit. It guarantees absolute axial alignment (centring) between the drive’s axis of rotation and the geometric centre of the measuring vessel. Any minimal eccentricity would inevitably generate asymmetrical shear gradients in the fluid and severely compromise the reproducibility of the viscosity data.

Vibration mechanics and resonance suppression

High rotational speeds in viscous or heterogeneous media generate high-frequency lateral vibrations due to uneven flow resistance. The geometric design of the IKA Holder MV 1 is statically engineered precisely to absorb these mechanical vibrations and prevent them from being transmitted to the stand system. This effective resonance suppression physically eliminates noise signals in the sensitive torque transducers of the connected stirrers or rheometers. The signal-to-noise ratio (SNR) of the rheological measurement curves is thereby significantly optimised.

Material integrity and ergonomics in everyday laboratory use

To withstand high mechanical stresses over the long term and prevent torsion under load, the mount is manufactured from solid, industrial-grade metal alloys. All surfaces are protected against the effects of aggressive solvents, acid vapours and alkalis by means of special surface treatment processes. The design enables the user to clamp and release the vessels quickly and reproducibly, which massively accelerates throughput during serial measurement runs in a regulated quality management environment, without compromising mechanical positioning accuracy.

Individual requirements & accessories

The IKA Holder MV 1 is a purely mechanical fixing element. To carry out a reliable rheological measurement, you must use the corresponding measuring vessel and a torque-measuring stirrer or viscometer from IKA. For completely vibration-free installation, we also recommend a solid double-cross-sleeve system and a heavy-duty H-frame stand. Please feel free to contact our specialist procurement service at any time for a structurally sound configuration of your measurement setup.
