Ideal for a small number of tubes, its the perfect rack for microbiology
and immunology labs. Fill the racks from the top and retrieve tubes
easily by pressing the rack down on a bench until the short legs touch. Fits either 1.5mL or 0.5mL tubes. Models with a hold-down pressure cap are designed specifically for incubation applications using 1.5mL tubes. The hold-down disk keeps continuous pressure on the tube caps and prevents them from opening due to internal air expansion. The rack floats and remains immersed at a constant level regardless of water level. Both Round Floating Bubble Rack styles are made of buoyant foam-filled TPX (polymethylpentene) and are steam autoclavable at 250F (121C).
