Round Microcentrifuge Floating Bubble Racks with Hold-Down Disk

Hold-Down Disk Maintains Constant Pressure on Tube Caps

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 (0.75″)
• Steam autoclavable at 121 °C (250 °F)
