The iCELLis™ bioreactor system is an automated, single-use, fixed-bed bioreactor that provides controlled cell growth conditions for adherent cells. Available in three formats, they deliver scalable performance from 0.5 to 500 m², supporting process development through clinical and commercial production of gene therapies, vaccines, and other products. These systems simplify and intensify processes from low-density seed train to final product, enabling faster achievement of clinical milestones and market entry.

These features include:

Productivity and scalability

• A compact, closed, high-cell-density fixed-bed, resulting in high productivity and streamlined operations
• Predictable scalability from bench-top (0.5 m²) to large-scale manufacturing (500 m²)
• Significant decrease in operational costs and capital investments compared to classical 2D flatware due to simplified handling and reduced footprint

Cell culture environment

• Optimized media falling film (aka “waterfall”) that provides high levels of oxygenation with low shear
• A fixed-bed acting as natural cell retention device, enabling media perfusion or recirculation and low shear mixing

Automation and integration

• Advanced automation systems for efficient and robust maintenance of cell culture critical parameters; 21 CFR Part 11 compliant software
• Fully integrated, single-use sensors for pH, dissolved oxygen (DO), pressure, and biomass, reusable temperature sensor through a thermowell
• A set of tubing assemblies, compatible with tube welding and aseptic connectors, specifically designed to perform key bioreactor operations
