I've never used this for flow cytometry but we used to use it for
fermentation work. I think we used to use it at 0.1-0.3% working volume
but that was in a very foamy yeast fermentation that would otherwise
have emptied itself out of the outflow pipe.

So I thought the ideal thing would be to have it in a squidgy bottle (at 1% in water) that I could squirt in when I'm emptying the waste and adding bleach. But it doesn't inhibit foam sufficiently.
