I recommend using an air-impermeable oil like Paratone over the hassle of capillaries. People often say that oil kills their crystals, but in my own experience, that rarely happens. I think it is more likely due to mishandling as working with oil does require some practice.
Once you get used to it, oils are very easy to work with. You can work with your oil mounted crystals at room temperature or flash freeze for cryo-collection. Ho Ho Leung Ng University of Hawaii at Manoa Assistant Professor, Department of Chemistry h...@hawaii.edu
