Testing performed by our in-house service team:
The Biostat B Bioprocess System passed all tests and was found to be fully functional:
- We verified the system startup and ensured the successful initialization of all core modules.
- We tested the touchscreen display's responsiveness and accuracy.
- We checked the operation of all peristaltic pumps for medium addition and base delivery.
- We tested the temperature and agitation control systems for proper regulation and stability.
- We verified the pH and DO probes using standard buffer solutions and ensured accurate readings.
- We confirmed the proper operation of the heating element for consistent heat distribution.
- We verified the accuracy of the vessel and feed scales.
- We evaluated the gas flow control and sparging functions using NIST-calibrated mass flow meters.
- We confirmed the function of the cooling water distribution components for effective heat removal.
- We performed a cleaning cycle and verified that all fluid lines were free from blockages and contamination.
