<p>A method and apparatus are disclosed for improved transfer and delivery of biological media used in tissue cell cultures. The media are reduced to powdered form, and then placed inside a cartridge or bag (1). The media are then sterilized within the bag (1) by the use of gamma irradiation. The cartridge or bag (1) is shipped to an end user, who reconstitutes the powder into solution. Sterilized water is pumped through the cartridge or bag (1), and solution exits from an outlet in the cartridge or bag (1) to a sterilized vessel (13). The solution can then be added to a tissue culture. The method is advantageous in that it does not require the solution to be filtered to be sterile, thus eliminating product losses during the filtering process. The method is also advantageous in that there is no direct handling of the powder after sterilization, thus greatly reducing the chance that the solution will be contaminated.</p> |
