Abstract

See full text

A device for removing or replacing solvent in a liquid sample containing macromolecules includes a concentration chamber having an aperture adjacent to the upper end of the concentration chamber which is arranged to receive and tightly fix the outlet of a detachable auxiliary reservoir. In methods employing the device, the concentration chamber is filled with part of a liquid sample to a predetermined level, and a detachable auxiliary upper reservoir containing the rest of the liquid sample is tightly fixed to the aperture adjacent to the upper end of the concentration chamber to successively deliver additional liquid sample as the concentration is progressing, or a detachable auxiliary upper reservoir containing a solvent or buffer solution is tightly fixed to the aperture adjacent to the upper end of the concentration chamber to successively deliver solvent or buffer solution as a replacement for the liquid absorbed by an absorption material.
