A heat exchange module for use in a chemical, pharmaceutical or biological reactor system includes a generally hollow body having an interior space for receiving a replaceable or single use reactant container, and at least one thermally conductive surface adapted to contact the replaceable reactant container to facilitate heat transfer, a fluid circulation path formed within the body between an outer wall of the body and an inner wall of the body through which a heat exchange fluid can be circulated, and at least one baffle protruding from the inner wall of the body into the interior space.

Temperature controlling surfaces and support structures

Disclosed herein are embodiments of a valve assembly for preventing dead leg spaces in a container or tubing, the embodiments including a three-way valve system for controlling back-pressure in a fluid generating device, such as a single-use high pressure bioreactor. Also disclosed is a pressurized reactor system for bioprocessing, comprising a single-use container including a flexible wall or a semi-rigid wall.

Disposable valve and flexible containers for pressurized bioreactors

Disclosed is a single-use bioreactor bag design providing substantially equivalent maximum shear rate at the impeller tip and average or bulk shear rate over a range of power per unit working volume and rpm needed for bioculture processing. The uniformity in shear profile of the bag design providing a unique advantage when used as a scale-down or scale-up platform. Also disclosed is a linearly scalable, single-use, bioreactor system for use in carrying out a scalable biomanufacturing process, the system comprising two single-use bioreactor bags of different volumes, wherein the ratio H/D of the height of the working volume H to the diameter D of the tank, or of the bag is equal to about 1.5, and the bulk shear in each of the bags is substantially constant. The disclosed small scale system models larger scale systems from both a shear/scalability/performance basis and also from a validation and regulatory basis. In summary, the 10L bioreactor system disclosed provides for 'linear scalability' by using the same or substantially simulating the same vessel geometry, gas sparging system, impeller shape and type, polymer composition of the flexible bag/components, process control system, and shear rates as larger 50-5000 L systems.

Linearly scalable single use bioreactor system

A heat exchange module for use in a chemical, pharmaceutical or biological reactor system can include a body configured to be disposed in the reactor system having an inner replaceable reactant container is disclosed. The body can further include at least one thermally conductive surface adapted to contact the inner replaceable reactant container to facilitate heat transfer. Furthermore, the heat exchange module can include a heat exchanger disposed within the module body and can include a fluid circulation path through which a heat exchange fluid can be circulated.
