Adapts to Evolving Seed Train Strategies
One Production Seed Train for Classic Fed-Batch or Intensified Processes
The Biostat® RM is an integral component of seed trains for commercial manufacturers. By using the Biostat® RM 200 bioreactor in intensified mode with the corresponding Flexsafe® RM bags, biomanufacturers can reduce production bioreactor culture days by up to 20% using high inoculation and maintaining titer. The Flexsafe® RM and Flexsafe STR® bags also use the same film, streamlining validation.
Effortless End-to-End Scalability from 2 L to 200 L volumes
The Biostat® RM portfolio offers customers a simple scalability solution by using only 2 rocker platforms for a variety of Flexsafe® RM bags from 2 L and up to 200 L in basic, optical and perfusion configurations. Both types of rockers share the same control tower based on the Biobrain® automation platform, further eliminating the possibility for human error and device incompatibilities.
Saving Space and Time With Unique 200 L Rocker Design
The Biostat® RM portfolio helps streamline process transfer between product development and manufacturing thanks to the unique Biostat® RM 200 rocking motion bioreactor which meets commercial manufacturing regulatory norms and requirements. RM 200 does not use submerse gassing or stirrer elements, thus provides a gentle environment for all cell types, especially shear-stress-sensitive cell lines.

There's no difference. Both methods stand for a controlled cultivation of shear-stress-sensitive cell lines and bioconjugates.
The Flexsafe® RM bag is a disposable bag optimized for cell cultivation. It can be equipped with different measurement methods, such as optical pH and DO probes or viable biomass measurement (BioPAT® Viamass port). Furthermore, a perfusion membrane can be integrated.
Rocking motion mixing technology is ideal for cell cultivation with low shear stress. It is hassle free and applicable to all cell types, including mammalian cells, plant cells, insect cells and microbial cells.
Yes, it is well suited for process intensification (e.g., Seed Train Intensification (N-1 Perfusion), High Cell Density Cell Banking). The advanced process control by BioPAT® sensors like BioPAT® Viamass & BioPAT® Trace allows an easy set-up of permeate and bleed flow. The integrated weight control of the rocker and the gravimetrical control of substrats ends in an advanced process control.
