Abstract
A device for concentrating and/or purifying macromolecules in a solution has a concentration chamber (1) with a sample reservoir (2) for a liquid sample to be processed, a filter (3) for filtering the liquid sample, and a filtrate container (4) for collecting the filtrate. A gas pressure differential is created and maintained across the filter and a sealing cap (5) for the sample reservoir (2), which has an opening (6) for permitting gas flow in one direction and blocking aerosol or liquid flow in an opposed direction. The present invention also provides apparatus and methods employing the device.
