They provide low-level agitation as this is their main purpose. For example, it is not ideal to disrupt the tissue when chemically fixing tissues for incubation. When carrying out blotting applications rocker shaker can be of great use. There needs to be careful handling when dealing with fragile membranes, especially for western blot protein analysis. There is less kinetic energy in the rocking motion most especially when blocking membranes. This sort of activity allows your blot to function effectively.
