Hi!
I just wonder if there is a good replacement for R007101643, a piston seal for our Agilent prep hplc.
I have placed the part last October but it has not been shipped yet due to the part being obsolete.
I am using a replacement from ASI (200-1222) but the shape is a bit different, leading to the pumps producing erratic flow rates.
Could you please give an advice on that?
Thank you!
Best,
Joonseok
