ABSTRACT:
An apparatus to take aseptic samples from bioreactors or other aseptic or sterile containers is disclosed. The invention comprises a hollow cannula (20), a septum (28) which seals a pre-sterilized sample tube (27) and an ultraviolet lamp (22). The cannula is connected to a bioreactor which is to be sampled. The ultraviolet lamp is used to produce light which will sterilize the surface of the septum and cannula prior to sampling, thus maintaining asepsis of both the bioreactor and the sample.
