The brand new Sartobind® Phenyl Mini presents 20 mL membrane volume, which enables bioprocess prospects a lot easier scale-up and is a great in good shape to the manufacture of diagnostic merchandise.

Columns that have values of File ≤ three are quite prone to give an equal and appropriate separation for just about any sample. When the first separation is comparatively "quick," as indicated by greatly divided peaks (resolutions Rs » 2), acceptable separation to the substitution column could end result for values of F > three. In any case, the column Along with the smallest value of F is almost certainly to supply a similar and suitable separation on the sample.
