Apologies if this isn't chemistry enough for chemistry.se. I'm happy to go elsewhere if there are suggestions.
Blue + Red = Purple is arbitrary here. If any different colors might make this more feasible, please say so (preferably with some explanation as to why).
I'm interested in having a jug of purple liquid.
When I turn it upside-down, it will empty through two bottlenecks into two smaller jugs. I would like for one of the smaller jugs to now contain red liquid, and the other to contain blue. Eg, I would like for one bottlenecks to actively filter out the red/blue portions of the original purple liquid.
This process has to be repeatable.
That is, I should be able to turn this contraption back over on itself and the blue/red will recombine to be purple, and then for the separation of colors to happen again when it's flipped a third time. It's not very suitable for me if this system only works a few times before losing its punch, but it may be acceptable if I had to replace or clean filters once every 50 or 100 filtrations.
Looking forward to some affirmative answers, or even some suggestions on how to better search for this.
