1. A bioreactor comprising:
a flexible container;
a first tubular connector and a second tubular connector projecting from the first tubular connector, the first tubular connector and the second tubular connector being at least partially disposed within the flexible container, the first tubular connector being more flexible than the second tubular connector, the first tubular connector having a length that comprises at least 20% of a combined length of the first tubular connector and the second tubular connector;
at least one mixing element disposed on the second tubular connector; and
a drive shaft disposed within the first tubular connector and the second tubular connector such that rotation of the drive shaft facilitates rotation of the first tubular connector and the second tubular connector within the flexible container.
