Claim Text:
1. A bioreactor chamber assembly comprising: a base and a cap configured to be coupled together to define an internal chamber; the base and cap each comprising a plurality of respective interengaging flanges to allow the base and cap to be releasably coupled together axially relative to a longitudinal axis bisecting the base and cap by rotation of at least one of the base and cap about the longitudinal axis; the flanges at each of the base and cap being respectively spaced apart in a direction around the longitudinal axis by gap regions configured to be occupied by at least a portion of the flange of the respective opposing base or cap, each flange having an abutment surface extending radially relative to the axis, the abutment surfaces at the base configured to slide over the abutment surfaces at the cap in touching contact by rotation of at least one of the base and cap about the axis such that at least a part of the flange of the base and the flange of the cap overlap in the axial direction to couple and lock the base and cap axially relative to one another; wherein each flange of the abutment surfaces extends in a circumferential direction around the longitudinal axis; wherein at least one of the abutment surfaces extends in a circumferential direction at an angle transverse to a plane perpendicular to the longitudinal axis such that as the flanges of the base and the flanges of the cap are slid over one another the base and cap are drawn together axially, wherein the respective interengaging flanges project radially outward from both the base and cap.
