ABSTRACT:
Means for developing a plurality of chromatograms simultaneously without prior equilibration are disclosed. When the means of the invention are used, the chromatograms are vertically positioned with their lower ends in developing fluid, their vertical edges equidistant from a solid wall member, and spacing between chromatograms to permit air flow. The means comprise a rack for use in a developing tank and in which the chromatograms are vertically supported in spaced slits, the ends of which are equidistant from a wall member when in the developing tank.
