4. You noticed that during a lab-scale bioreactor run the tubing that pumps in a 1 M NaOH- solution for pH correction has leaked a small amount. The fermentation has run fine, nothing fell out of the spill tray since it was only a small leak, and it does not interfere with the experimental results. But what actions do you take immediately, what are the safety considerations and what could you do to prevent this happening in the next fermentation run? Leak Pump O Spill tray Tubing
