About This Product
In gravity chromatography the solvent runs down through the packed column under its own weight, with no applied pressure. The fritted disc holds the packing in place and the PTFE stopcock controls the outflow. Columns with a frit and suction tube, or with indentations for a cotton plug, are listed separately.
