I have had my G1005A sequencer 2 years and have had the flask cap assembly
replaced 5 times so far. The new assembly works fine with the initial flask
put in. (Although there were a couple of new assemblies that didn't work
either.) The flask stops turning in the cap and a seal is created. When I take
that flask out to clean or replace it and then put it or another one back in,
the flask just turns inside the cap and no seal is created. The loss of a good
seal will also happen over time while on the instrument, with no flask
replacement. The problem appears to me to be the o-ring between the
flask and the cap. It appears as though it gets distorted. I have had a lot
of downtime because of this problem. Has anyone else had this happen to them?
If so, what remedy do you use? Each time it has happened, HP ends up replacing
the whole cap assembly.
Thanks,
Jeanne
