There are national lists of core facilities to help you discover specialty services? 

Some scientific and analytical techniques are so specialized that there may not be a core facility at the University of Arizona that does what you need. Before you look out-of-state, double check at the UA’s RII core facility list or take a look at the Arizona Cores Network in iLab

The Association of Biomolecular Resource Facilities has a national core facilities database called the ABRF Core Marketplace (in collaboration with the Vermont Genetics Network). BioImaging North America has a list of core facilities as well. Another national core facility database can be found at the eagle-i network (includes over 40 institutions).
