ABSTRACT:
A device having a processing chamber, for electroelution and/or dialysis of a substance carried in a sample with respect to an external liquid medium. The chamber has a closed end and an opening at the other end, sufficiently large to permit a sample, particularly a gel contained sample, to be inserted thereto. The chamber has two portals, each laterally disposed with respect to the opening. A tubular membrane covers the portals, and is sealingly fixed onto an outside surface of the housing. The device provides high yield recovery, saves time and allows for easy handling, especially regarding loading an unloading of small volume samples for dialysis, or inserting the gel slice containing the macromolecule sample. The device may be partially immersed in the liquid medium, with the opening above the liquid surface. Optionally, the device may be hermetically sealed via a cap, and fully immersed in the liquid medium.
