Rotor-stators consist of a fast-spinning inner rotor with a stationary outer sheath (stator) to homogenize samples through mechanical tearing, shear fluid forces, and / or cavitation (the rapid forming and collapsing of bubbles). Rotor-stators are broadly capable of homogenizing a wide variety of tissues or cells, although very tough tissue can be a problem. Most rotor-stators homogenize a single sample at a time, although some high-throughput models and continuous / in-line models are available.
Keep in mind: rotor-stator homogenizers require a probe to operate and not all rotor-stators come with a probe. Be sure you have all the necessary parts before you buy.
