The Scienceware® 5ml centrifuge tube rack is designed to store, organize and transport new 5ml centrifuge tubes offered by Eppendorf and other companies as well as other tubes with a diameter of 13-16mm. The company says that as these tubes are a relatively new size to the laboratory market, there are very few racks available to accommodate their width and height. Made of durable and corrosion resistant white polypropylene, the 40-place rack has a top shelf height of 3.4cm. The end plates have handles for easy transport and stacking. It is steam autoclavable at 121°C. Bel-Art
