ABSTRACT:
A molecule separator device for isolating molecules having at least two separable properties and within a solution. The device includes a housing, and at least two molecule collection media disposed within the housing, whereby each such medium captures molecules exhibiting a respective property. In one embodiment, a first membrane captures only molecules with an ionic and/or hydrophobic and/or affinity attraction property while a second membrane captures only such molecules that additionally fall within a particular molecular weight range. A preferred housing is cylindrical for acceptance within a centrifuge, and is constructed of a plurality of releasably-connected compartments. The collection media is sequentially situated and centrifugation of the housing drives the solution through the media. Because of separation and subsequent collection in one device of molecules bearing multiple properties, the present invention permits rapid and efficient isolation of molecules and micro-particulate having a plurality of identification characteristics.
