These absorption chromatography columns can be used for rapid preparative separations with moderate resolution. Each has a Teflon® stopcock and a spherical top outer joint. The column is constructed using medium wall tubing for extra durability. Glass wool (not supplied) is used to support the column packing. The lower end of the column has a round bottom. The column can be used with optional CG-1201 flow controllers and CG-1200 reservoirs. Connections between the column, reservoir and flow control adapter are made with spherical joints connected with CG-150 stainless steel clamps.
