Abstract
A pliable centrifuge tube array includes a number of tubes having collars which are interconnected by flexible tethers that permit the tubes to diverge when they are placed into holes in a centrifuge rotor. The tubes have a noncircular cross section providing grooves or apexes in which pellets of dense material preferentially collect. In some embodiments, the tethers or tubes have a latching mechanism such as mating projections and sockets which, when engaged, hold the tubes together in close array. The tubes may have individual lids which can be opened and closed simultaneously with a prying tool specially designed for the purpose.
