ABSTRACT:
A sample fraction collector for sequentially collecting a plurality of samples of uniform volume despite variations in sample flow rate and/or viscosity comprises means defining a sample chamber, an outlet conduit means having a rotatable valve means therein, rack means for sequentially positioning a plurality of individual receptacles beneath a dispensing outlet of said outlet conduit means, a generally U-shaped tube for holding an electrolytic solution with first and second electrode means positioned in one leg and a pressure tube communicating between the other leg and the sample chamber. A control system is actuated by the electrolytic solution contacting both electrode means to energize the rack means to the next position and then to rotate the valve means to the open position for a period of time to drain the sample chamber.
