Abstract
A method of recovering a bead support from an emulsion includes supplying an aqueous surfactant solution into a centrifuge tube; supplying a hydrophobic liquid over the surfactant solution in the centrifuge tube, wherein a ratio of the volume of the aqueous surfactant solution to the volume of the hydrophobic liquid is not greater than 0.5; and applying an emulsion over the hydrophobic liquid while centrifuging, the emulsion comprising a dispersed aqueous phase including the bead support, the emulsion breaking and material of the dispersed phase preferentially partitioning to the surfactant solution.
