Abstract: A disposable container in which samples can be routinely prepared for analysis. The container has a generally cylindrical magazine containing a plurality of open top sample preparation chambers, each of which is provided with an inlet/outlet port at the bottom, thereof; and a distributor valve beneath the magazine. Channels are provided in the top of the valve, extending between openings in the top of the valve, so that each channel provides fluid flow communication between the ports of the chambers located above the openings in the channel. The valve and magazine can be rotated relative to one another about the central axis of the magazine, so that the openings in the channels can be located beneath the ports of different combinations of chambers to provide fluid flow communication between different chambers.
