Thank for @cyclopath for the tips, I am new to posting and mostly a casual lurker. Those two threads you linked are in fact the ones that I started on.
The Amazon bottle filler that @ky_cbd suggests is the one I was referencing from previous posts I explored. My only concern with it is that it seems the solution has to pass through the machine and I can really tell if solution touches anything other than the plastic tubing its being sucked through. @ky_cbd can you shed some light on the internals?
I’ve also seen a lab bottle top dispenser
But I used wide mouth bottles so I don’t think these would work for me.
