(b)(4).Lot# corrected to 74f1602711.The sample was returned for evaluation.A visual exam was performed and no defects were observed.Functional testing was performed by placing the column into a fully functioning concha neptune heater.The neptune was turned on: temperature set at 37 degrees c, max rainout, invasive mode.After approximately 3-4 minutes, the low water indicator lamp came on confirming the low water float in the column was fully functional.The check valve discs in all three valves would move as the column valves were turned from one side to the other, showing the discs themselves were free to move.A syringe connected to the upper tube was used to push and pull upper check valves.The column to bottle valve and the bottle to column dump valve opened and closed freely.The returned column was connected to a concha water bottle in the correct positioning and both upper and lower tubes were punctured into the concha water bottle.The lower tubing filled as expected.(con't) other remarks: the column was then connected to a comfort flo circuit and cannula using a 3lpm flow.The nasal nares were occluded allowing the pressure to build in the bottle until the comfort flo relief valve actuated representing the worst case back pressure for the system then disconnected the airflow.The column allowed the water bottle air pressure to escape through the column without pushing the column water level up to the circuit thus functioning appropriately.Based on the investigation performed, the reported complaint could not be confirmed.There were no functional issues found with the returned column.
