Micro Sample Tube Racks, each

These round floating bubble racks can incubate 8 to 20 tubes in a beaker of water. Perfect for use in microbiology and immunology labs. Made to be used in beakers. The racks are loaded from the top and the tubes are easily removed by pressing the rack down on a bench until the short legs touch. Molded from buoyant foam-filled TPXR (polymethylpentene) with tiny bubbles throughout. They are steam autoclavable at 121°C.
