Its innovative cube-shaped biocontainer design integrates a highly efficient internal mixing paddle coupled with a dynamic sparger. The system is non-invasive as the paddle and the sparger are enclosed in a medical grade ultra low-density polyethylene resin (ULDPE) sleeve, made from the same contact material as the bag itself. The paddle is coupled on top of the vessel with the mechanical mixing head.
The superior mixing capabilities and the innovative sparging device enable the PadReactor bioreactor to achieve greater productivity compared to cylindrical bioreactors.
The PadReactor system utilizes disposable mixing biocontainers made from TK8 bioprocess film. The product-contacting layer of TK8 film is blow-extruded in-house by Pall Life Sciences under cleanroom conditions using medical-grade ULDPE. It is then laminated to create a gas barrier film of exceptional cleanliness, strength, and clarity that is animal derived component free (ADCF) and complies fully with USP Class VI requirements.
Mixing is achieved when the integrated paddle/sparger inside the biocontainers rotates.
The PadReactor single-use bioreactor consists of the following:
Drive Unit – The flexible drive unit allows the system to cultivate cells in disposable biocontainers. One drive unit is adapted for various disposable mixing biocontainer sizes. Each system comes with the appropriate mixing stick for your container.
Mobile Retaining Tank – The purpose of the retaining tank is to support the mixing biocontainer and provide mobility before and after operation. Various tank sizes and options are available.
Bioreactor Vessel – The reactor vessel uses an innovative biocontainer design that allows a non-invasive connection to the mixer. Mixing is achieved when the integrated paddle/sparger inside the biocontainer rotates within the biocontainer.
Controller (optional)– ez-Control from Applikon configured to work with PadReactor system.

Mixing Capabilities ModelThe PadReactor system utilizes a cube-shaped vessel design agitated with a paddle-shaped mixing element rotating in an elliptical motion. The corners of the vessel act as baffles to prevent vortexing and ensure robust mixing with very low shear stress. In order to model the mixing capabilities of the PadReactor system, Computational Fluid Dynamics (CFD) analysis has been conducted in different volumes and at different mixing speeds. As demonstrated on pictures mixing, turbulent but low shear mixing is easily achieved, even at low speeds. The cube-shaped vessel and paddle mixing element design of the PadReactor system provides effective mixing advantages. These advantages have been shown to require lower power input, improved gas transfer and improved productivity when compared to bioreactors with cylindrical vessels.
