Traditional capillary is a pain to handle, unless you have a rock sized crystal.

Dear All,

I would be interested to learn of other crystallographers' experience in their use of glass capillaries for protein crystal growth and X-ray diffraction clarity.
There are many types of glass available - quartz, soda glass, borosilicate, etc. Are there specific types which people prefer for best results overall?

Best wishes,
