Reviewer: Fred Barker from Denver, CO  
Have used Agilent 1100 HPLC G1311A Quat Pump in the past without issue. After many years G1311A Quat Pump was ready for replacing and this refurbished option was a great choice. It shipped quickly, arrived early, and was in great condition. Will definitely be back.
