Testing performed by our in-house service team:
The Sartorius Stedim Biostat B Bioreactor Controller passed all tests and was found to be fully functional:
- We verified system startup and confirmed successful initialization of all core modules.
- We inspected and tested the control panel, display, and interface for responsiveness and accuracy.
- We verified the pH and DO probes using standard buffer solutions and ensured accurate readings.
- We tested the temperature and agitation control systems for proper regulation and stability.
- We evaluated the gas flow control, overlay, and sparging functions to confirm consistent delivery and response.
- We tested the pump's medium-addition and base-delivery functions.
- We reviewed alarm functions and safety interlocks to ensure the system responds appropriately.
