These tubes are designed for general chromatographic analysis. The tops are tooled for rubber stopper fit and the tubes are fabricated with sealed-in coarse porosity fritted discs. The outflow tubes are large in diameter to eliminate the smearing of the definition bands of effluent caused by the tube being filled, and the solvent mixed before being expelled. The outflow tubes are long enough to protrude through a rubber stoppe…

The 10x300mm PYREX® column is designed for general chromatographic column separations. The top is tooled for a No. 00 rubber stopper fit. A PTFE (Polytetrafluorethylene) Product Standard stopcock with a No. 2 plug is provided for better column control. Sealed into the column in a coarse porosity (40 to 60 µm) fritted disc. The volume below the disc is minimized to prevent mixing and to allow clear, sharp, band definition. For…
