Description
Automatic separation of a two-phase mixture without separating funnel. Two-phase mixtures are completely applied to the column and the phase boundary is determined without additional work. The special membrane stops the flow automatically when the lower phase has run out. The upper phase remains in the column so that both phases are available for further analysis. The columns must not be operated under vacuum or pressure. PTL for solvents that are lighter than water, e.g. for diethyl ether, hexane.
