Re: bam-a-flavine
Hello Scott,
Unfortunately, I am NOT chasing killies in Florida ...! :-)
A correction: It is NOT Kordon's acriflavin, but a KODAK product. It
used to be product #18843, but I bought it 10-15 years ago and they
might have changed the number.
The stock solution, if kept in the dark, is quite stable.
Best,
George
