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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
250 words
An apparatus for the separation of chemical substances and the production of sterile solutions which comprises a column, an ion exchange agent placed into said column; at least one filter in said column; plugs closing said column at the ends thereof; the body of each plug containing a piercing duct having an inner expansion chamber; a resilient stopper placed in each of said expansion chambers whose free extended length exceeds the length of said expansion chamber, and where each resilient stopper has longitudinal notches on its external surface extending over the stopper end facing said column so that said longitudinal notches communicate with the piercing duct; a closing cone on each stopper provided on an end opposite to its notched end engaging the edges of the end portion of said piercing duct of the plug; said cone being located in said expansion chamber in a direction away from said column thus ensuring a tight seal for the piercing duct; a cover for each plug adapted for attachment to a vessel containing chemical substances; an internal hollow pressure rod for each of said covers, having a transverse portion at the end thereof; said rod passing through the end portion of the piercing duct of the plug and engaging with its transverse portion, the closing cone of the stopper so that upon attachment of the cover to said plug, the stopper can be compressed by said pressure rod, thereby allowing communication with the piercing duct and the vessel containing said chemical substances.
Claim 2
Independent Claim
250 words
An apparatus for the separation of chemical substances and the production of sterile solutions which comprises a column, an ion exchange agent placed into said column; at least one filter in said column; plugs closing said column at the ends thereof; the body of each plug containing a piercing duct having an inner expansion chamber; a resilient stopper placed in each of said expansion chambers whose free extended length exceeds the length of said expansion chamber, and where each resilient stopper has longitudinal notches on its external surface extending over the stopper end facing said column so that said longitudinal notches communicate with the piercing duct; a closing cone on each stopper provided on an end opposite to its notched end engaging the edges of the end portion of said piercing duct of the plug; said cone being located in said expansion chamber in a direction away from said column thus ensuring a tight seal for the piercing duct; a cover for each plug adapted for attachment to a vessel containing chemical substances; an internal hollow pressure rod for each of said covers, having a transverse portion at the end thereof; said rod passing through the end portion of the piercing duct of the plug and engaging with its transverse portion, the closing cone of the stopper so that upon attachment of the cover to said plug, the stopper can be compressed by said pressure rod, thereby allowing communication with the piercing duct and the vessel containing said chemical substances.
Claim 3
Dependent Claim
