ok so i have this long glass tube - or 2 and in a movie i recall seing some lab with long tubes full of oil with colored water dripping down thru it - and it gave me an idea.

if one were to take a long glass tube - like 2m or so - even 1m or so - then attatched a tap to the bottom and top - like a sep funnel tap - filled the tube with their np solvent of choice - then put perhaps a cm of basic solution in the tube - which would sink(dont use dcm - unless u plan to do the exact reverse of this plan - which may be better or worse idk)

now the taps are set to perhaps 2 drops per second - they must be exactly the same drip speed.
the top tap gets it mhrb basic solution fed to it by gravity pulling on the liquid - as the resevoir is mounted above the height of the np solvent tube.
the bottom drips out into a basic water collection vessel - which is then pumped back up into the resevoir.

The idea behind this is that the np solvent will only ever be in contact with a very small amount of basic solution - each drop get pushed thru so much np solvent - and each drop is so small - that it can be almost exhausted by the time it reaches the bottom of the np tube
the basic solution just cycles thru the np solvent - at a much better ratio than if u simply mix the 2 together.
it can be automated by leaving the drips at exactly the same interval - and perhaps putting a timer on the pump - or a water level indicator on the collection vessel below the np tube.




what u guys think ?

Interesting idea.... as you said, could also be thought about for other types of extractions.

I wonder though how the pump would stand a highly basified liquid.

I also expect that even if it does stand a pH 14 water or something, it would have to be an A/B because the mimosa solids would block the pump and what not.

heres an old post from another board... cacti related, but relates well i think

"
blend cactus
add small amount of water
add sodium hydroxide to solution and stir and mix well in suitable safe container.
leave for a day or two to break down all plant matter, stirring and mixing when chance arises.

**** note this next part is experimental and takes some time but seems to show plenty of potential.

have a container with xylene ready that can accommodate the basified solution as well..so a container say of 3 liters and there is a liter of xylene in it with 2 spare liters for your cactus solution to drop into..

Now the tricky bit...drip from the container of cactus solution drop by drop into the xylene...in other words a sep funnel dripping it slowly into the xylene would be cool or a small hole in the container which allows the solution to drip slowly.

As the basified solution drops into the solution drop by drop you are exposing large amounts of solvent to tiny amounts of basified solution which by rights should pull every bit of alkaloid from the drop straight into the solvent, the rest will sink to the bottom. if collection container is on a magnetic stirrer even better as some slight agitation as the drops hit the moving solvent would certainly be helpful.

This is experimental as i have said, the idea being that you are exposing the mescaline alkaloid in freebase form to solvent in a reversed ratio to other existing teks...it should release it faster into the solvent as opposed to pouring a bottle of xylene on top of basified solution and shaking and stirring hoping that all mesc freebase at some point comes into contact with solvent and is pulled across...this method has generally meant multiple pulls before you get most of it...I've never been satisfied that u actually get it all with multiple pulls and to be honest it's a right pain the ass to have to do multiple pulls and titrate multiple times...there has to be more economical and brainier ways to access these freebase alkaloids we seek."

One kind of pump that I can think of that would work very well assuming fully filtered basified solution as from an A/B would be a parastaltic pump like this.

The high pH fluid only contacts tubing which can be silicon or other flexible chemically resistant tubing. I have seen a relatively inexpensive (<$50) 12 volt pump that moves 50 ml/min. I suppose a simple speed controller could be added to reduce the flow rate.
