This durable wet/dry test tube rack is comprised of 3 pieces and is easy to disassemble for cleaning, stacking, and storage. It is autoclavable and holds up to 40 test tubes (20 mm). Made from a special blend of polypropylene that allows the rack to sink in a water bath and maintain its stability, even in agitated water. The top tier also features an alphanumeric reference grid.

Made in the USA.
