Preformed mixing bag for dry powder, apparatus, method and system for using same

Abstract

A mixing bag having an interior mixing chamber having a volume sufficient to receive a predetermined weight of substantially dry material and a selected volume of process compatible solution to form a solution having the material in suspension with a selected concentration is shown. The mixing bag includes at least two sealable openings. One opening is configured for at least one of enabling transporting the substantially dry material into the interior mixing chamber, enabling agitation of the material and process compatible solution in the interior mixing chamber to form the solution and enabling withdrawal of the solution at the selected concentration. The other opening is configured for at least one of injection of a process compatible solution into the interior mixing chamber to form the solution, enabling agitation of the material and process compatible solution in the interior mixing chamber and enabling withdrawal of the solution.

1 . A mixing bag comprising 
 an interior mixing chamber having a volume sufficient to receive a predetermined weight of substantially dry material capable of remaining in suspension in a process compatible solution and a selected volume of process compatible solution to for a solution having the material in suspension with a selected concentration, said interior mixing chamber having a first end and a second end wherein said second end is located in an opposed spaced relationship to said first end; and    at least two sealable openings wherein one of said at least two sealable openings extends from a location exterior to the mixing bag and into communication with the interior mixing chamber at said first end and which is configured for at least one of enabling transporting of material into the interior mixing chamber, enabling agitation of the material and process compatible solution in the interior mixing chamber to form a solution having the material in suspension with a selected concentration and enabling withdrawal of the solution at said selected concentration from the interior mixing chamber and the other of said at least two openings extends from a location exterior to the mixing bag and into communication with the interior mixing chamber at said second end and which is configured for at least one of enabling injection of a process compatible solution into the interior mixing chamber to form a solution having the material in suspension, enabling agitation of the material and process compatible solution in the interior mixing chamber to form a solution having material in suspension with a selected concentration and enabling withdrawal of the solution at said selected concentration from the interior mixing chamber.
