Heathrow One Rack Half-Size Delrin Test Tube Racks resist most acids, solvents and heat. They provide extra tough storage for smaller spaces. They are molded in a single, continuous piece. No assembly is required and there are no detachable pieces. Racks are made of Delrin® fiberglass-reinforced polyoxymethylene (POM), an engineered polymer developed by DuPont for exceptional chemical and heat resistance.
Racks have a molded index coordinates and flat labeling areas keep samples organized. Half-size racks are convenient for incubators, fume hoods, refrigerators, and other tight spaces. Racks made with Delrin are autoclavable, and come in a case of eight.
