Hi Rainer,
I have 5 magnets now with a total of 6 helium transfer lines. 5 of them
are nonflexible types. Once I purchased the flexible transfer line from
Bruker 2 years ago for our new system, I use it all the time to fill all 5
magnets. It seems to transfer He quite fast compared to all others I have.
I always keep He pressure below 1 psi during transfer. I also find it easy
to maneuver.
