Hi,
about 20 years ago I have an incident of a broken NMR tube stuck inside the probe. The faculty who is trying to help out in my absence tried inserting and ejecting the rotors several times to get the experiment going. When I removed the probe I could poured out the broken glass. The piling action of inserting another tube causes the broken glass sideways braking the insert supporting the NMR coil.
We instituted a no fault policy, "report anything that you felt is not right at the NMR spectrometer and you will not be responsible (don't have to worry about paying) for any breakage discovered!" Since then I still have broken NMR tubes in or near the spectrometer, but nothing serious in 20 years.
Best of luck
Regards
Kim

Subject: AMMRL: sign off sheets?
Hello All,
Over my first 4 years here at BSU I did not find any broken tubes in the NMR lab. In the last three months I have found shards from two tubes. I am confident that I had cleaned up the shards from the first tube so this is a new incident. After the first incident I asked the PI's to survey their groups and get the person who broke that tube to talk to me and apparently no one did it.
I suspect that if that is true a I could get a PNAS paper on the spontaneous appearance of shards of precision glass, hmm, doubt that would get pass the review process, Achems Razor might get in the way.
Does anyone have a sign-off sheet that they are willing to share and covers things like the responsibility to report breaking a tube? Has any one managed to find a way to overcome the reluctance to confess? I always try to say that I am not looking for retribution but rather corrective actions.
Regards,
Joe
