Single-use fermenter for microbial applications
In biopharmaceutical production, achieving high cell density and maintaining sterile conditions are critical. Conventional fermenters often pose challenges such as contamination risk and lengthy cleaning protocols, impacting productivity and product safety.

Enhance productivity with ready-to-use fermenters
The Biostat STR® Microbial by Sartorius AG is a single-use fermenter designed for microbial applications. It combines the flexibility of single-use technology with the performance of traditional stainless-steel systems. This fermenter supports high cell density cultivation with metrics like OD600 >300, kLa of 675 1/h, and stirring speeds up to 500 rpm. Equipped with Flexsafe STR® bags, it reduces setup and cleaning time, ensuring faster batch-to-batch turnover. The Biobrain® automation platform offers precise control over cultivation parameters, making it ideal for producing high-value products such as pDNA, fAbs, recombinant proteins, and vaccines. With a working volume of up to 40 liters, it’s engineered for robust performance and easy process scaling.
