Abstract
The disclosure describes an ambient or low pressure device for separating polynucleotide fragments from a mixture of polynucleotide fragments comprises a tube having an upper solution input chamber, a lower eluant receiving chamber, and a fixed unit of separation media supported therein. The separation media has nonpolar separation surfaces which are free from multivalent cations which would react with counterion to form an insoluble polar coating on the surface of the separation media.
