Reza, Almost any fraction collector will do. If you have a pack rat colleague around NY City, find an unused, but working Gilson fraction collector, with a rack (which I surprising number of people use without knowing what the rack is for). In our teaching lab we have about 7 of them we occasionally use for the students. Although it does a serpentine collection on 60 tubes, which is OK, more importantly, it has a drop counter, as well as timed advance.
To me, my biggest dilemma was trying to get the samples out. We used thin-walled tubes that allowed the bottom to be punctured. So you needed that whole setup to puncture the tube and drain it into the fraction collector to get fractions from highest to lowest density. Clunky, but it works. Do you have that?
