Abstract
An automated process for filling a sealed receptacle (1) with a fluid under aseptic conditions is disclosed. The sealed receptacle has at least one part (2B) made of a material capable of being pierced by a hollow needle (8R) and sufficiently flexible to close itself up again after removal of the hollow needle. In the automated process, the part (2B) of the sealed receptacle is pierced using a hollow filling needle (8R) which is in contact with the fluid to be channeled into the receptacle (1). During the process of filling the receptacle (1), the perforating end of the hollow filling needle (8R) is maintained under aseptic conditions by means of laminar gas flow.
