So with a few successful extractions behind him, swim is thinking he really enjoys working with clear liquid and from a sep funnel as opposed to gallon wine jugs and pipettes.
Filtering the bark after the acid soaks seems to be kinda tricky sometimes. Current train of thought involves running it through a kitchen strainer a couple times, then a stainless steel screen that is like pipe screen mesh a couple times, put in fridge and let settle, decant, then paper filters. Swim likes to finish with buchner filter because it sucks everything out of the bark.
It would be nice to be able to run at least 750ml through before having to change out filter paper.
The question of perilite....would it make an adequate filter aid? Would you put it into funnel? Or mix it with your soup? And finally, would its porosity be a problem in terms of holding on to the filtrate?
Everything i say is fictional, I just wanna be cool and fit in.

Perlite is not suitable - it is far too absorbent.

Use a cotton wool plug tucked snugly but not too firmly into the neck of a large kitchen funnel. Have a second one - funnel, plug and all - ready for when it gets clogged. Then you can transfer the unfiltered liquid and carry on unimpeded. Quicker, cheaper, easier and more effective than a paper filter.

Save the pulp for the Buchner if you like, or brew it up a couple more times until the amount of stuff trapped becomes insignificant. Using more apparatus can increase the possibility for losses - it's a matter of learning to judge what is an acceptable balance.


No need to "swim" either. It's much too shallow, you'll scrape your knees!




“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli

My advice: Filtering will never be really possible/easy, buuuut you can just do sedimentation.

Time is your friend and instead of letting something drip through a filter over 10 h which may eventually clogg anyways,

just let your acidic soup stand for 10 h. Then you can slowly decant it and you will see a huge amount of reddish particles will have formed a dense sediement on the bottom. Then this mixture could even be filtered, not really needed, but as all these *big* particles are off, you can do it much easier. And this time also not even a real filter paper is needed, just use a tissue or maybe 2 of them and place them on top of a sieve. Your new soup will run smoothly through this and in the end this is filtered well enough.

Just in case that you evaporate stuff afterwards, you will get new particles in your soup, so just let it sit for 5 - 10 h again. Maybe boring to wait, but you dont have to do stuff inbetween and it really makes a difference for phase separation in the last step. Thumbs up
