Plastic vials with firmly integrated glass insert are the more robust and less expensive version of glass vials with fused-in inserts

SPE columns (phase separation), 30 mL column volume, CHROMABOND PTL ICP-50N-1 2 % NaN₃ (sodium azide)Automatic separation of a two phase mixture without separation funnel. Two phase mixtures are completely applied to the column and the phase boundary is determined without further work. The special membrane automatically stops the flow when the lower phase has passed. The upper phase remains in the column, thus both phases are available for futher analysis. Columns must not be run with vacuum or pressure. PTL for solvents lighter than water, e. g.,
