Bioreactor vessels and associated bioreactor systems

A bioreactor vessel for removable connection to a bioreactor module, the vessel comprising:

• a chamber defined by top, bottom and side walls;
• a rigid ledge projecting to a side of the vessel and having an externally-facing connection port;
• and
• a conduit at least partly defining a fluid flow path between the chamber and the externally-facing connection port, a chamber end of the conduit being in fluid communication with the chamber and the other end of the conduit being connected to the externally-facing connection port,
• wherein the conduit is defined internally within the ledge.

A bioreactor system, including a cell culture module comprising:

• a base including a receiving station for removably receiving a bioreactor vessel;
• and
• a bioreactor vessel having a chamber defined at least by bottom and side walls, and having a fluid port through one of the bottom and side walls;
• wherein the receiving station includes a fluid port, located such that the port in the vessel wall is in registration with the fluid port in the receiving station when the vessel is received in the receiving station, thereby defining a fluid flow path between the base and the vessel chamber.
