Nalgene 5930 Polypropylene Test Tube Racks have handles that make carrying easy. Holes are keyed with molded-in numbers and letters for easy identification of tubes. When empty, can stack with any other racks of the same length. Higher specific gravity than water so stays submerged in a water bath—won't float. Superior chemical resistance. Not autoclavable. Polypropylene construction.
Array: 6 x 12
