3 Litre Bioreactor Assembly (Microbial Fermentation)

Air inlet pipe used to meet the oxygen demand of a culture. Allows a sterile gas stream to be sparged into the vessel. This is a “drilled hole” or “flute” sparger, which can be used when high gas flow rates are required, as it has a minimal pressure drop. The holes in this pipe are located in the bottom of the tube, to ensure that the media is driven out by the gas stream. Includes 10 mm Hex Nut, Washer and 8.5 x 2.5 mm Silicone O-ring.

Compatible with 3 & 5 Litre Vessels, 10mm port.

The following impeller is available for the agitator assemblies, both lipseal and magnetically coupled types. Fits onto the standard 8 mm diameter shaft, includes size M3 x 5 mm hex set-screw.

Compatible with 2 & 3 Litre Vessels, 8mm shaft.

Baffles are used to increase the mixing efficiency. Without baffles, the medium flow can become laminar, causing poor mixing efficiency and mass transfer.
