Abstract
A modified test tube is provided which can sit on any flat surface unaided by a test tube rack. The modified test tube includes a tubular containment portion and tubular neck portion. The containment portion has a bottom surface preferably provided with a plurality of legs and a closed end. The neck portion is angled approximately 45.degree. relative to the flattened surface and has a mouth which opens parallel to the flattened bottom surface. The legs enable the test tube to sit prone on any flat surface by itself, unaided by a rack, and the bent neck portion prevents the contents from spilling from the test tube. This design enables the contents within the test tube to be easily monitored without moving the test tube. A test tube rack is further provided for storing the test tubes. The test tube rack is generally a rectangular member having a plurality of cavities, spaced such that each does not intersect another. The cavities are preferably provided with openings alternately provided in opposite sides of the rack.
