Laboratory-scale microalgae cultivation system
Harness precise cultivation capabilities for microalgae with advanced photobioreactor systems, ensuring optimal growth conditions, scalability, and high-density cultures for diverse applications ranging from nutraceuticals to carbon capture.

Cultivates and Processes Microalgae for Diverse Applications
The LS series from Subitec offers a range of flat-panel airlift photobioreactor systems tailored for microalgae cultivation across laboratory and industrial scales. These systems enhance cultivation with precise control over growth conditions, thanks to features such as LED illumination and CO2 regulation. Essential for sectors like pharmaceuticals, food supplements, cosmetics, and environmental applications, they support products ranging from spirulina powder to algal biofuels.
Each model, from the compact LS6 to the expansive LS180, supports different production scales with respective cultivation volumes of 6 to 180 liters. The systems operate with minimal floor space, owing to their optimized photosynthetic surface areas, maximizing yield while minimizing energy consumption. Subitec photobioreactors feature hermetically sealed designs to prevent contamination, and automation capabilities integrated via touchscreens for simple operation.
Constructed from high-quality, corrosion-resistant materials, they assure compliance with stringent industry standards and integrate seamlessly with existing production lines. These systems are ideal for pharmaceutical manufacturers, food supplement producers, cosmetics companies, and facilities focused on carbon capture or wastewater treatment, providing flexibility and efficiency for developing algae-derived products.
