Columns for gravity flow phase separation
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 futher analysis.
- Columns must not be run with vacuum or pressure
PTS for solvents heavier than water, e.g., for trichloromethane, dichloromethane maximum size 150 mL
PTL for solvents lighter than water, e.g., for diethyl ether, hexane maximum size 70 mL
