An important chromatographic separation method is column chromatography (SC). The most common method is liquid chromatography consisting of a mobile phase (liquid or gaseous) and a stationary phase (e.g. solid packing material in a cylindrical tube). Due to the varying degrees of adsorption of the substance to be separated (in the mobile phase) on the stationary phase, preparative purification of substance mixtures of different polarity is achieved, for example.420000-0000 is a plain column with an integral reservoir. It is tapered to a 2 mm bore capillary tip and has a top tooled for a #2 rubber stopper
Features & Benefits
Manufactured from borosilicate glass 3.3
420100 series are general purpose columns for quick separations. Their funnel-shaped tops permit easy filling and hold additional solvent
420300 series are basic columns used for many separations in adsorption and ion exchange chromatography
Glass wool (not supplied) is used to support column packing
