This microbial bioreactor combines efficiency with robust control:

Single-use Flexsafe STR Microbial bag featuring two 6‑blade Rushton impellers and a ring‑sparger with upward‑facing holes for superior mixing and gas transfer.
Equipped with redundant optical DO and electrochemical pH sensors, alongside two KPC ports for multi‑use probes—offering full flexibility in sensor configurations.
Delivered gamma‑irradiated and ready-to-use, complete with gas‑line filters and sterile Opta® connectors to simplify setup.
Includes a redundant exhaust line, with option for single-use exhaust cooler, reducing the risk of filter blockage and minimizing water loss in the exhaust.
Configurable with advanced PAT modules such as BioPAT Trace and Viamass, plus perfusion options like ATF and TFF systems.
Tubing diameters and connector types (Opta® SFT/AseptiQuik®/MPC) are adjustable to meet specific process needs.

The Biostat STR Microbial 50 L system is ideal for:

High‑density microbial fermentations, including E. coli pDNA production and recombinant protein expression.
Pilot-scale microbial processes requiring precise sensor control and process intensification.
Environments demanding robust performance, traceability, and GMP compliance.
Plug‑and‑play integration with existing Biostat STR® systems, offering smooth scale-up from smaller platforms like Ambr® 250.

The Biostat STR Microbial 50 L – Sartorius delivers a complete solution for demanding microbial fermentation. With its combination of advanced mixing, redundant sensors, ready‑to‑use configuration, and modular upgrade options, it supports high-performance bioprocessing workflows with flexibility and compliance.
