Microbial Fermenters

Microbial Bioreactors and Fermenters from PD to Commercial Manufacturing

Sartorius provides a specialized range of fermenters designed for microbial cultivation, meeting the specific requirements of microbial cultures, including high oxygen demand and effective management of metabolic heat. 

With expertise in automation and engineering, Sartorius provides robust, scalable systems ensuring reliable control of culture conditions. The advanced analytical capabilities and intuitive usage support a Quality by Design approach, optimizing process design and its understanding.  
While stainless steel bioreactors have been the traditional choice for larger -scale microbial applications, the biopharmaceutical industry's demand for flexibility has led to the rise of single-use solutions. Sartorius's portfolio includes innovative single-use bioreactors like the Ambr® 250, Biostat® RM and Biostat STR® Microbial, offering high performance and scalability as well as reliable seed train solutions from early product development to commercial manufacturing.
