Abstract
An apparatus for separation of chemical substances and production of sterile solutions, which comprises a column closed with plugs at the ends thereof and containing an ion-exchange agent and at least one filter. In the body of each plug there is a piercing duct with an inner expansion chamber wherein a resilient stopper is placed, which stopper is provided with longitudinal notches at its external surface extending over the end surface of the stopper facing the column so that said longitudinal notches communicate with the piercing duct of the plug. At the opposite end of the stopper there is a closing cone abutting with its surface upon the edges of the end portion of the piercing duct thus ensuring tight sealing of the latter. Each of the plugs is provided with a cover adapted to be attached to a vessel for solutions and having an inner hollow pressure rod passing through the end portion of the piercing duct of the plug and activating, by its end, the closing cone of the stopper so that upon putting the cover on the plug the stopper is compressed by the rod and the piercing duct of the plug becomes open for the flow of solutions.
