These autoclavable test tube racks are molded in a single, continuous piece. No assembly is required and no detachable pieces, especially ones that can be lost. There is the choice of Delrin®fiberglass-reinforced polyoxymethylene (POM), an important engineering polymer developed by DuPont which has exceptional chemical and heat resistance (except to open flames). The racks include molded-in index coordinates and flat areas for convenient labeling.
