<p>A plant for filling vials and similar containers comprising syringes and filling nozzles as well as nozzles for nitrogen injection is submitted to one or more washings and to a steam sterilisation; then sterile nitrogen is fed to said plant at slight overpressure to maintain the plant sterile until it is used again. The device to carry out said method comprises a line for nitrogen injection, of the type normally used for nitrogen injection into vials, provided with an offtake connected by means of valves to the lines for water and steam feeding in order to alternatively feed water, steam or nitrogen to said syringes and filling nozzles, and steam or nitrogen to the injection nozzles and to the sterile filter for nitrogen filtration. The device is preferably automatically operated. <IMAGE></p> |
