Bel-Art Scienceware™ Round Microcentrifuge Floating Bubble Racks with Hold

Specifically designed for incubating 1.5 mL microcentrifuge tubes, this rack includes a hold-down disk which maintains a constant pressure on the tube caps and prevents them from opening during internal air expansion. The polypropylene disk with threaded handle screws into the foam-filled TPX® polymethylpentene plastic rack and holds tubes firmly in place. Rack floats while microcentrifuge tubes remain immersed at a constant depth. Leg length: 19 mm (³/₄ in.). Steam autoclavable at 121°C (250°F).
