Each sample rack can include a sample tube for holding a soil sample and a filter cup for receiving an extracted fraction of the soil sample. An extractor module of the fractionation system can include an extractor assembly and a filter assembly. A control system can control the relative positioning of the plurality of sample racks via the drive system, the relative movement between the extractor assembly and the sample tube, and the relative movement between the filter assembly and the filter cup.
