Thanks so much to all who responded to my email regarding
implementing and enforcing tube rules. I had 29 responses in 3 days!
Of the 29 respondents, 18 enforce a tube rule. The most common rule
is requiring a Wilmad 507PP or higher or an equivalent quality from
other vendors. In terms of enforcing, there were some great ideas out
there including fines for those caught with low quality tubes or revoking
NMR priviledges. Another idea is to have your stockroom only
distribute appropriate quality tubes and insist that users only buy there.
Other managers rely exclusively on education.
I also want to thank those who informed me that broken inserts are not
necessarily the result of warped tubes. Other potential sources are a
bad spinner, spin miscalibration, and intermittant air flow.
Please contact me directly if you'd like copies of the original
responses.
Best Wishes,
Mike
