Sorbact Absorption Dressing Sorbact® Absorption Dressing is a sterile, bacteria and fungi-binding wound dressing. It consists of a green Sorbact® wound contact layer combined with an absorbent core and a white backing film. Sorbact® Absorption Dressing absorbs and retains exudate, thereby reducing the risk of maceration and enabling a moist wound environment. The dressing can be used in compression therapy.
