Pope Wiped-Film Molecular Stills are a special type of short-path distillation equipment. These are continuous mode systems, as opposed to simple batch mode boiling flask stills (the latter often referred to as “short-paths”, though ironically, these are not truly short path designs as discussed in the next paragraph).

The effect of centrifugation is, therefore, dependent upon the mass of the particle. The convenience of using the relative centrifugal force is that the value for the mass of the particle is eliminated from the equation, permitting more general comparisons of centrifuge performance: RCF = fc/fg = Mω 2 r/Mg = ω 2 r × g -1.

The principle of the centrifugation technique is to separate the particles suspended in liquid media under the influence of a centrifugal field. These are placed either in tubes or bottles in a rotor in the centrifuge. Particles differing in sizes, shape and density are separated as their sedimentation rate is different.
