Tube rack

A portable rack for medical or laboratory tubes where it is desirable that the tubes be supported in either generally vertical or generally horizontal positions as the user desires. The illustrated rack includes a center panel having openings for receiving the tubes and a pair of end panels, one longer and one shorter. The geometry of the holder allows the holder to be supported with the larger end panel resting on a supporting surface so as to position the tubes extending generally horizontally. The geometry of the rack further allows the rack to be positioned upon the unattached edges of the side panels so that the tubes are held generally upright. A handle is provided for carrying the rack so that the tubes will be extending generally horizontally. The openings are shaped to hold the tubes in a fixed rotational orientation as may be desired for particular tubes.
