Disclosed is a test tube rack designed to hold a plurality of test tubes suspended in a bath. The rack is a unitary design having an outer rim with an internal diameter sized to fit over a rim of a vessel that forms the bath. The rack includes a plurality of openings sized to fit a test tube. A top end of each opening includes a plurality of raised portions and a plurality of lowered portions. The raised portions support an outwardly flared rim of a test tube placed in the opening and thus suspends the test tube in the vessel. A central hub joins the plurality of openings together.

The rack is economical and readily scalable to work in conjunction with a variety of vessel sizes.
