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.
