Test Tube Mixer (Figure 1-23). The Test Tube Mixer has both vortex and shaking actions and allows very slow
operation without sacrificing high speed performance. Any desired mix homogeneity can be achieved (and repeated)
according to viscosity, miscibility, and container. The mixer is equipped with interchangeable snap-on heads, which are a
cup head and a platform head.
