Hello again!
I have this problem solved. Many thanks to Dee-Hua Huang at Scripps for sending me some of the older brown version which work. I also received much-appreciated help from Karen-Ann Smith at UNM, Greg Heffron at Harvard, Edwin Rivera at USF, Dan Bearden at NOAA, Jürgen Schulte at Binghamton U, and Arnold Itkin at NMR Associates Inc.!!
Thanks again, -Hirsch
Hey Spinlanders,
We now have a torn diaphragm in two of the grey pneumatic valves which sit atop the magnets on ARX and other older Bruker systems. This valve dumps remaining eject air pressure to allow the sample to drop after the Lift is turned off. Last I checked, Bruker would not sell the diaphragm separately, and their price for an entire valve was unaffordable. Does anyone have one of these valves surplus which we may have? Alternatively, has anyone ever determined a suitable replacement for the entire valve, or found a source for replacement diaphragms?
Thank you, -Hirsch
