Tips for keeping your Eppendorf BioFlo® Bioreactor in good working order:
Install inline filters on the gas supply lines feeding the controller (especially when using MFCs), and replace them annually.
If autoclaving is performed, maintain a log of autoclave cycles for the following:
Glass vessels
pH probes
DO probes
Any other probes located within the vessel
Adhere to the manufacturer’s specified autoclave life cycles and storage recommendations.
Replace vessel O-rings annually.
When using optical sensors, keep all open connections covered with the supplied protective caps to prevent fouling or contamination of connection points.
If the reactor will not be used for an extended period, power it down and, if possible, disconnect it from the power source. These systems rely on high-power electronics that generate significant heat, which can degrade components over time.
Have the impeller shaft drive assembly rebuilt annually to prevent component wear and potential contamination of the media.
Inspect the rollers in peristaltic pump heads for rolling resistance. They should rotate freely; remove any accumulated residue using a mild detergent to prevent tubing wear.
Perform annual preventive maintenance to verify that the system is operating in accordance with manufacturer specifications.

Eppendorf BioFlo® Bioreactors Troubleshooting Tips:
If pH, DO, or temperature readings look unstable or incorrect:
Check calibration status first; Expired calibration is the most common cause.
Inspect the membranes of the DO probes, the electrolyte level (if applicable), and optical patches (for fouling or delamination).
Confirm that the temperature compensation is functioning and the proper probe polarization time (DO) is achieved.
If acid/base additions overshoot:
Check pump calibration (flow rate drift is common), and tubing elasticity (older tubing might lead to a delayed response).
Reduce pump speed or pulse duration, and verify probe response time.
If temperature fluctuates:
Check the water supply (flow rate and temperature stability), and the heating blanket integrity (for glass vessels)
Inspect RTD / temperature probe seating
Eliminate ambient drafts or HVAC effects
