I have been presented with crystals grown in nmr tubes on two separate occasions. Both diffracted very well and thankfully, neither required a magnetic field for optimisation. On the first occasion I did use the initial sample as a seed stock.

Dear all users, I got my crystals at the bottom of the tube on ice just before I started to screen crystals. Those crystals' shapes were good but easy to melt when I harvested them. I shot these crystals. They only diffracted to 7A to 8A. Has anyone ever met this situation before? How to improve?
