A simple apparatus is described for use in one-dimensional ascending paper chromato-graphy. A large glass tube of 4 cm in internal diameter and 45 cm in height is stoppered with a cork stopper which is provided, on the inner side, with five to six each of stainless steel staples, plastic rings, and paper clips, all parallel to each other. Strips of filter paper (2×40 cm) are held by paper clips, one to each clip, and a small glass rod is placed at the lower part of each paper strip, the end of which is immersed in the developing solvent. Eight of these glass tubes can be stood in a circle on a round holder of 22 cm in diameter. When compared with the existing appartus, this simple apparatus has the following advantages. (a) The cost is very low, (b) both the space and volume of solvent are small, (c) filter paper strips are kept apart, (d) there are no parts than can be damaged, (e) no special procedures are necessary for the operation or measurement of Rf, and (f) ascending speed of the solvent is slightly faster.
