Hi,

I want to characterise the mixing performance of a micromixer.
I have a fluorecent marker like fluorescein, but I now
need to find another liquid, which "does not mix so well"
with it so I can characterise their mixing.

I believe in the macroworld, this is done with glycerol,
but I need to do it in a tiny chamber!  Any suggestion is
welcome.  Thank you for your time!
