An elongated flow-through vacuum degassing apparatus includes an elongated gas and liquid impermeable outer tube and one or more gas-permeable, liquid-impermeable elongated inner tubes extending coaxially within the outer tube. The degassing apparatus further includes a vacuum source adaptor extending from a side wall of the outer tube and co-extensively with a vacuum source coupling aperture in the outer tube so as to create a sealed axial vacuum chamber between the outer tube and the inner tubes. The apparatus also includes inlet and outlet connection structures operably coupled to respective portions of the outer tube and the inner tubes to further enable a sealed engagement between the outer tube and the inner tubes, and to provide for connection devices for operably coupling the degassing apparatus of the present invention to respective components in a chromatographic system. The degassing apparatus is sufficiently flexible so as to be readily manipulatable into desired configurations.
