Patent ID: 8735144

Claim:
A bioreactor chamber assembly comprising: a chamber comprising a plurality of modules arranged to be coupled together to form the chamber, the chamber being arranged wherein one or more barriers are provided within the chamber to define a plurality of fluid reservoirs, at least one module of the chamber having a fluid inlet aperture and a fluid outlet aperture arranged to establish fluid flow through a reservoir, wherein respective modules are provided with one or more respective complementary formations arranged such that the modules are configured to be coupled to one another, the complementary formations comprising a resiliently deformable material and arranged to form a liquid-tight seal between the respective formations without a requirement for a separate seal element; wherein the complementary formations comprise a first generally planar surface feature on a first module of the plurality of modules that interacts with a corresponding second generally planar surface feature on a second module of the plurality of modules such that the first and second generally planar surface features are sufficiently resiliently deformable so as to form a liquid-tight seal.
