Intensify your seed train
Solutions to increase cell density and improve process efficiency in your upstream bioprocess.
Seed Train Platform
Future-proof your manufacturing with tailored solutions for seed train intensification
Seed train intensification allows for significantly higher cell densities compared to traditional batch processes. This is achieved through methods such as using perfusion processes, or integrating cryopreservation techniques to streamline the inoculation of production bioreactors.
- Cellicon® Cell Retention Solution separates and retains cells in a culture while allowing the surrounding media and waste products to pass through, maintaining high cell densities, improving cell viability, and facilitating continuous production.
- Mobius® High Cell Density Cryopreservation Assemblies enable seed train inoculation of cells at higher densities, ( > 50 x 106 cells/mL) and larger volumes and allows for direct inoculation of bioreactors.

Cellicon® Cell Retention Solution: High Throughput and Reproducible Performance

The Cellicon® Cell Retention Solution includes a lab-scale flat sheet filter assembly and controller for perfused seed trains, featuring an intuitive piping and instrumentation diagram (P&ID) for process visualization. The process-scale version, with Mobius® Cell Retention System and Bio4C ACE™ software, offers scalable sizes (50–2000 L) ensuring easy integration with bioreactors. They offer:
- High throughput and low fouling
- Low crossflow and cell shear
- Predictable linear scalability from lab to manufacturing scale
- Reliable and reproducible performance
- Comprehensive monitoring and precise control
They are easy to use, install and are ready to process in minutes.
Mobius® High Cell Density Cryopreservation Assemblies: Lower Risk of Contamination and Improved Reproducibility

These assemblies are specifically designed to facilitate the freeze and thaw of cryopreserved cells in either ultra-low temperature (-80 °C format) or liquid nitrogen (-196 °C format) freezers. Both formats are available in two assembly bag sizes of 100 mL and 250 mL in a 5-bag manifold. This multi-bag design:
- Significantly reduces environmental contamination risk compared to vials or single bag operations
- Improves process reproducibility by providing uniform inoculation feed across multiple campaigns
