Rotor-stator homogenizers - The importance of the generator probe

by NiuShangshen

With mechanical, rotor-stator homogenizing the most important component is the homogenizer probe also known as the generator.  The size of this precision crafter component can vary from the diameter of a pencil for 0.01-10ml sample volumes to much larger units having batch capacities up to 19,000 liters or, for in-line units, capabilities of 68,000 liters/hr. Rotor speeds vary from 3,000 rpm for large units to 8,000-60,000 rpm for the smaller units. In principle, the rotor speed of the homogenizer should be doubled for each halving of the rotor diameter. It is not the rpm's of the motor but the tip velocity of the rotor that is the important operating parameter. Other factors such as rotor-stator design, which there are many, materials used in construction, and ease of leaning are also important factors to consider in selecting a rotor stator homogenizer.
