Dear Michael, I work with capillaries in a regular bases to grow crystal and use them for RT data collection or cryogenic temperature data collection at home source or at synchrotron sources. I like better borosilicate glass capillaries from Triana (http://www.trianatech.com/), as Patrick has already mentioned, for the cylindrical type but if I need capillaries with a reservoir them I go for the standard power diffraction capillaries from http://www.capillarytubes.co.uk/acatalog/Borosilicate_Glass_Capillary_Tubes.htmlwhich are similar to those from Hampton ( http://www.capillarytubes.co.uk/acatalog/Borosilicate_Glass_Capillary_Tubes.html), etc.
All of them will give you some background but any of them will affect dramatically your data quality. You can do a search in ActaD or F and get good inputs on that (=*367 articles match your search capillaries*). On my hands borosilicate capillaries are easier to handle than Quartz capillaries and probably cheaper. Gavi. ____________________________________ Dr. José A.
