[3dem] Gatan 914 cryotransfer holder

[Bowman, Valorie D]

Dear Frank,
We had this problem at Purdue as well and Paul was able to figure it out.
Is the body of the workstation frosting up where it joins the shaft?  If so
it, the O ring has worn out.  There is an O ring at the joint between the
shaft and the cup.  Replace it and you should be back to normal.

Cheers,

Valorie
