ABSTRACT:
A reusable microconcentrator device may be disassembled, cleaned and reassembled before use. The microconcentrator device of the invention is typically useful in filtering and separating small samples of solutions and suspensions. The microconcentrator device of the invention includes an elongate sample sleeve, a base element which can be removable and replaceably coupled to a centrifugal portion of the sleeve, a compliant membrane compressing feature, and a disposable membrane. Preferably, the base element includes an O-ring which compresses the membrane to seal it to the centrifugal surface of an annular ledge portion of the sleeve, which also forms a deadstop. Among the advantages of the microconcentrator device of the invention is that a reliable retentate volume remains following filtration. The elements of the microcentrator device can also be permanently assembled to one another.
