I am interested in getting a system that can replace much of the dull work as sample injection, buffer mixing, column switching and so on. One advantage, as I understand it, with the Äkta system compared to the Biorad is that Äkta has automatic buffer mixing which is preferential when working with optimization of pH and ion strength gradients. This is also true for the PE biosystems Biocad 700E. Any other experiences?? I have not heard so much from people working with the Biocad700E or Biovision systems.
