Lab Scale airlift Glass bioreactor

RICH SMART airlift fermenter & bioreactor is a gas-liquid bioreactor based on the principle of ventilation pipes, without any mechanical stirring.

Types of Airlift Bioreactor

Internal Loop Airlift Bioreactor

As for the internal loop airlift bioreactors, compressed air is used for aeration and agitation. The turbulence caused by the gas/fluid flow ensures adequate mixing of the liquid.  The gas used for agitation can act to either side, introduce new molecules to the mixture inside the bioreactor, or remove specific metabolic molecules produced by microorganisms.

Airlift Bioreactor Diagram

An airlift bioreactor works by stirring cultured substance using gas. Air/Gas is fed through a sparger ring into the bottom of a concentric tube, which directs the circulation of both air bubbles and liquid. At the top of the bioreactor, there is a gas separator to remove gaseous substances. Air bubbles flow upwards within the central draft tube; some of these bubbles coalesce at the top of the column and exit, while others follow the degassed liquid and circulate downward from the area outside the draft tube.

Advantages of Airlift Bioreactor

Efficient gas-liquid dispersion with low power consumption

Improved fluidization characteristics

Low shear rate (have homogenous shear and stress forces throughout the entire bioreactor)

Excellent liquid-solid and gas-liquid mass transfer

Choose Your Controller

The airlift bioreactor controller can be customized with RS series controller, matching with the special airlift bioreactor vessel.

Applications of Airlift Bioreactor

Ideal for culturing cells that are too sensitive to the shear stress and heat generation caused by the mechanical agitation.

Pallet form fermentation; immobilized enzyme reactions.

SCP production from methanol as carbon substrate.

Typically, airlift bioreactors are used when the desired reactants and/or final products are in a gaseous state and for aerobic cell cultures.
