Biotech Fluidics, in collaboration with MOTT Corporation, has launched a new range of micro spargers for bioreactor applications that efficiently dissolve gases, promote cell growth, and provide agitation.     

A micro sparger is a device that introduces a gas such as air, oxygen, or carbon dioxide into a liquid by creating very small bubbles. Typically made from sintered porous materials like stainless steel, these devices create tiny bubbles that increase the surface area for gas-liquid contact, leading to more efficient mass transfer and enabling processes like aeration and fermentation.

Biotech Fluidics noted that its micro spargers can significantly reduce bubble size and increase gas transfer and volumetric mass transfer coefficient (kLa), resulting in reduced gas consumption and improved upstream reactor yields.

These micro spargers have proven to increase benchtop laboratory bioreactor and fermenter mass transfer rates by 100 percent to 400 percent compared to standard drilled pipes or single-opening dip tubes.

Biotech Fluidics offers a wide variety of porous metal sparger tips for laboratory and pilot-scale bioreactors and fermenters. With media grades ranging from 2 µm to 15 µm, the company can offer a micro sparger optimised to generate bubble sizes tailored to specific media, organism, and mass transfer requirements.  

Headquartered in Sweden, Biotech Fluidics is a leading supplier of fluidic system solutions, liquid transfer components, degassing systems, and innovative laboratory technologies to instrument developers, manufacturers, and distributors worldwide.
