Abstract
A gradient tube holder and method for securely supporting gradient tubes for observation and access to a gradient therein. The gradient tube holder is pedestal-mounted and includes gradient tube-receiving bores, the bores being formed adjacent an edge so that a longitudinal slot can be formed along the length of the bore. A light shield surrounds the slots to shield the slots against extraneous light thereby enhancing visibility of the gradient tubes.
