One characteristic of dispersion blade mixing is the creation of a vortex, which is helpful for incorporating solids. Desired Particle Size We mentioned particle size above and this is another factor that could contribute heavily to your decision. By studying the working principle of the two, we can see that the high shear homogenizer is mainly due to the high shear effect of the relative high speed motion between the stator and rotor, accompanied by strong cavitation the material particles were dispersed, refined and homogenized; and high-pressure homogenizer is mainly due to high-pressu. They also create slightly less flow, so they often cannot be used with as large a volume as lower-shear probes. In case youre unsure about dimensions, the specifications of most probes will tell you what volume range they are suitable for, which can act as a good guide. As a rough guide, to achieve optimal efficiency, the diameter of the generator probe should be roughly ten times smaller than the diameter of the vessel. However, there can be cases where its not that black and white. Aside from the obvious benefits of speeding up your process, improved efficiency also means you can lower heat generation (an inherent side effect of rotor-stator homogenization), which is particularly important for heat-sensitive samples. Wikidiffcom vs Stirrer - What's the difference? Mixing occurs when a sample is drawn in through one of the mixing heads while the blades rotate, and is then expelled at a high velocity through an opening in the stator. Also called a rotor-stator homogenizer or homogenizer, the most recognizable batch rotor-stator design is the toothed or slotted version. Other successful applications include emulsions for adhesives and ceramics, microencapsulation of essential oils, and food gums and pectin premixes. For stirrers, a magnetic stirrer wont create much shear, but an overhead model fitted with the right impeller might do just fine. The Differences Between an Agitator and a Homogenizer A. Tracton (Ed.
