An apparatus for dispensing a hazardous fluid into a container (30) comprises a body within which at least two hollow needles (22, 24) are positioned above a delivery septum (21). A container holder (40) receives a container (30) within an inner space (100), wherein during and for delivery of such a fluid into the container (30) the distal portions of the needles (22, 24) are adapted to be advanced across the delivery septum (21) and across the container septum (33) of the container (30). The container holder (40) and a piston (60) as a complementary closure surface of the body are moved together by a driving means until said closure surfaces meet, turning the inner space (100) accommodating the container (30) into a sealed space. A fuither relative movement of the needles (22, 24) against the container holder (40) allows the distal portions of the needles (22, 24) to first cross the delivery septum (21) and subsequently cross the container septum (33), both only after the creation of the sealed inner space (100). This effectively reduces the volume of the hot cell (100) and allows the check and evacuation of this space through a third conduit (23). |
