25L Airlift Fermentation Bioreactor for Cell Culture & Microbial Fermentation
Bailun’s 25L Airlift Fermentation Bioreactor is designed for laboratory and pilot-scale fermentation, cell culture, and low-shear bioprocess applications. Using advanced airlift circulation technology instead of traditional mechanical agitation, the system provides gentle mixing, efficient oxygen transfer, and stable cultivation conditions for sensitive biological cultures and microbial fermentation processes.
The 25L airlift fermentation bioreactor is widely used in biotechnology laboratories, pharmaceutical research centers, universities, algae cultivation projects, enzyme production, and pilot-scale bioprocess development.
Applications of 25L Airlift Fermentation Bioreactor
The 25L airlift bioreactor is suitable for a wide range of laboratory and pilot-scale applications, including:
Mammalian Cell Culture
Suspension Cell Culture
Microbial Fermentation
Algae Cultivation
Cyanobacteria Research
Recombinant Protein Expression
Enzyme Production
Plant Cell Culture
Biopharmaceutical Research
Pilot-Scale Bioprocess Development
The low-shear environment makes the system especially suitable for sensitive cells and shear-sensitive microorganisms.
Advantages of Airlift Fermentation Technology
Gentle Low Shear Cultivation
Traditional mechanical stirring systems may generate excessive shear force that damages delicate cells. The airlift circulation system minimizes turbulence and protects biological cultures.
Benefits include:
Improved cell viability
Reduced shear damage
Stable suspension conditions
Better fermentation performance
Improved product consistency
Ideal for mammalian cells, algae, recombinant microorganisms, and sensitive biological systems.
Efficient Oxygen Transfer Performance
The optimized airlift structure improves gas-liquid mass transfer and oxygen distribution throughout the vessel.
Advantages include:
High oxygen transfer efficiency
Uniform dissolved oxygen distribution
Enhanced nutrient circulation
Stable growth environment
This helps improve biomass productivity and fermentation performance.
Energy-Efficient Operation
Without large mechanical agitators, the system consumes less energy and generates less heat during operation.
Benefits include:
Lower operating costs
Reduced maintenance requirements
Minimal heat accumulation
Simplified operation
This makes the system suitable for continuous fermentation and pilot-scale operation.
Hygienic & Simplified Structure
The simplified internal structure reduces contamination risk and improves cleaning efficiency.
Features include:
Fewer moving components
Easy sterilization
Reduced maintenance
Improved operational reliability
The hygienic design is suitable for biotechnology and pharmaceutical research environments.
