Abstract
An anti-radial chromatographic device is disclosed preferably comprising an inner Petri dish nested concentrically within an outer Petri dish of slightly larger diameter. The bottom surface of the inner dish is spaced from the bottom surface of the outer dish to form a solvent-containing chamber. A annular wick contained in the annular space between the two dishes extends above the tops of the dishes and conducts the solvent upward to the lower surface of a downward-facing chromatographic plate resting on the wick.
