In effort to tighten the seal on the bioreactor, the hardware team has decided to increase the amount of helicoils on the bioreactor, from 4 to 8. Hopefully, this will tighten the connection between the bioreactor segments, thus increasing the seal. A better seal will prevent future leaks. Also, we learned that the hydrogen-detecting tape works in the solution. Therefore, it was unnecessary to have the inner ring compartment. Thus, we took the ring out.
