Please ensure all samples brought into the NMR labs are labeled using the tickets provided with the following details:
* Your Name
* Group or Lab Number
* Your sample reference
Please do not write or stick labels directly on the ESR tubes.
Broken tubes (i.e. tubes with jagged or fractured ends) are a potential hazard and are not to be used. Please take any such tubes to the glass workshop where they will grind them flat. The bottoms of tubes should be regularly checked for hairline cracks. NMR staff will confiscate broken ESR tubes.
* Minimum tube length is 25 cm.
Sample preparation must be done in your lab, not in ESR lab.
