A dye by any name would stain as red?
Does anyone else still make their own Kinyoun's Carbol Fuchsin Solution for
the AFB stain? If so, maybe you can help me. When you reorder Basic Fuchsin
do you go by the C.I. # (color index) or the catalogue #? I was taught to go
by CI #. It's been many years since I last ordered and my bottle had the cat
# B660-3 CI # 42500. So I pulled my order card and more dye from JT *****,
through V**. The bottle I received was named Basic Fuchsin Hydrochloride. OK
the old bottle didn't have "Hydrochloride" on the label but what's more is
that the CI number was wrong! It was Cat # B660-03 (right #) and CI #
42510(wrong CI#) I called V** and asked for a bottle with the correct CI
number (42500). I got it. Its name is Pararosanilin Hydrochloride CI 42500!
No mention of Basic Fuchsin anywhere on the label. Just looked it up in
AFIP, Ann Preece, and F.Carson's books- no mention of CI number. Which dye
would you use? Or am I'm going to have to do some QA with these two dyes?
