Fermentador RALF

Full flexibility

RALF supports batch, fed-batch and perfusion processes and offers maximum versatility by seamlessly integrating your preferred instrumentation and control equipment through a variety of interfaces. It is controlled by BioSCADA and meets stringent standards such as 21 CFR Part 11.

The vessel is positioned in front of the control tower for easy access from all directions. The compact control tower saves space and fits into any laboratory environment.

Three temperature options are available: a single-wall vessel with heating pad, a double-wall vessel for cell culture, and a special single-wall vessel with perfused baffles for microbial applications. This design provides efficient heat transfer. It is easier to transport and can be autoclaved in less time than conventional double-walled vessels.

Common supply connections simplify installation of multiple systems and minimize space requirements. The system offers customized solutions for optimal process conditions.

• Unique temperature control option
