Does anyone working in an academic institution have a need for some NMR standards in 5mm diameter, 8 inch tubes? Our SOPs require that we "expire" these after a few years, but as small molecules in sealed glass tubes they are likely good for a very long time. Ideally I'd like to donate these to a small college where there is a need, as replacement cost is over $1000.
