These durable racks are molded in a single, continuous piece—no assembly required and no detachable pieces. Racks are made of polypropylene or Delrin® fiberglass-reinforced polyoxymethylene (POM), an engineered polymer developed by DuPont to have exceptional chemical and heat resistance. Molded index coordinates and flat labeling areas keep samples organized. Half-size racks are convenient for incubators, fume hoods, refrigerators, and other tight spaces. All racks are autoclavable. Case of 8.
