Gilian Gilibrator Primary Flow Calibrator w/ Case. 3-Bubble Generators Used

We were able to power up and start charging using the AC adapter.

Gilibrator P/N D800268, seemed to charge but battery condition is unknown.
Bubble Generator P/N D800286, Range 20cc-6LPM.
Bubble Generator P/N 800285, Range 2-30 LPM.
AC Power Adapter.
Bubble Generator P/N D800286, Range 20cc-6LPM. The bottom of the chamber is not attached. Can this be repaired?

Carry case seems in good shape.

We do not have the means for testing beyond power up and we are unsure how to evaluate.

We are selling AS-IS, no returns as parts or repair due to the lack of testing.
