Dear Clemens,
The pump adapter is typically included with Varian NMR systems; however, I
haven't seen one provided with the Bruker systems.
We currently have three types of transfer lines from Bruker
Would it be possible to purchase a pump adapter directly from Bruker?
Best regards,
Weixing

Hi Ken
in general we recommend to pump it when it gets excessively cold during
transfers or when you think it takes a lot longer than usual to cool down.
This would indicate a soft vacuum.
So more need based than time based

Inspired both by recent discussions on the forum about capturing helium
during a fill and a recent visit by an engineer to our facility.
How often do you pump down your helium transfer line?
I will admit that we never have since I joined the facility in 2013 and I
didn't realize that you could.
1. Never
2. Every fill
3. Every year or more frequently
4. More than yearly
5. What? You can pump down a helium transfer line???
