Specifically designed for incubating 1.5 mL microcentrifuge tubes, this rack includes a hold-down disk to maintain a constant pressure on the tube caps and prevent them from opening during internal air expansion.

• Constant pressure on tube caps prevents unwanted opening
• Polymethylpentene plastic rack construction
• Rack floats while immersing microcentrifuge tubes
• Autoclavable

The polypropylene disk with threaded handle screws into a foam-filled TPX® PMP (polymethylpentene plastic) rack and holds tubes in place. The rack floats while microcentrifuge tubes remain immersed at a constant depth. Leg length is 19 mm (³/₄"). Steam autoclavable at 121°C (250°F).
