CHROMABOND SPE Columns, PTL

Key features

  • 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 further analysis
  • Columns must not be run with vacuum or pressure

    Recommended application

  • PTL: for solvents lighter than water, e.g., diethyl ether, hexane maximum size 70 mL
