KIT FOR STORAGE AND MIXING OF AGENTS OF WHICH AT LEAST ONE IS LIQUID

摘要

A kit for mixing comprises a housing (5) accommodating an ampoule (1) containing a solid (2) and a container (3) containing a pressurized solvent (4). A needle unit (13) comprises a first needle (16) the ends (17, 18) of which pierce rubber membranes closing the ampoule (1) and the container (3) to establish a transport channel through which pressurized solvent flows from the container (3) to the ampoule (1). The ampoule (1) is vented through a second needle (19) inserted through the membrane (9) of this ampoule and provided with a micro filter (20). A branch (21) on the needle (16) connecting the ampoule (1) and the container (3) is connected to a cylinder in which a piston (22) is driven by the pressure rising in the needle (16) when no more liquid can be transmitted to the ampoule (1). When the ampoule is full, the piston (22) releases a lock (24, 25) locking the needle unit (13) with its needles inserted in the ampoule (1) and the container (3).
