Steven:

I have found Coulter DNA Check beads work fairly well in UV. They are
fairly bright and get good CVs. I have tried beads from Polysciences made
for UV, but found the CVs to be horrendous. The DNA Checks have a very
broad exitation range, so I imagine they will also work at the higher
wavelengths. Good luck.
