Large extraction/ seperation vessel ideas here:

Swim is considering using DCM for a couple 500G MHRB extractions, or a single 1kG extraction.

He would like to avoid having to filter tons of basified ground plant matter. That being said, wouldnt it be convienant to have something in which:

-there was a large enough opening for which to easily dump plant matter into
-it was built out of HDPE 2 plastic, something unreactive that should withstand heat, pH and the chems used
-it was solid enough to withstand some light agitation without leaking
-it was able to be easily and safely modified into a seperation funnel of sorts so as to make life easy when it came time to separate the BOTTOM layer from the top aqueous layer.



A glass sep funnel... out of the question, too expensive and swim worries of glass etching etc with the high base

so he has been looking at HDPE carboys, water coolers, and even gas containers.

Many of these can be equipped with spigots, or possibly an attachment could be screwed on when it came time to separate: he thinks he could attach a nozzle, to the nozzle a bit of clear hose (to see when he reaches the aqueous layer) and at the end a clamp to stop the separation process when needed.

He thinks that knowing the volume of DCM added would make it easier for him to drain the bulk of it into one container, and then when he realizes he is getting close to the end, he could switch to another and finish the separation 'just in case' he drains off too much, that way he has smaller volume of liquids to work with if he has to go back and do something to clean up.



Any ideas or concearns regarding this?

here are some links:

maybe one of those superthick 5 gallon carboys with one of these come time to separate?
...though there may be problems with burping, then again there will only be small volume of DCM nessisary for extraction anyway



ewww here's a good one, but its starting to get spensive- that thing on the right caught my eye:

Filtering basic sludge is pure murder. Even teatowels and t-shirts will clog in seconds. An A/B will save you days of shredded nerves and frustration

Swim was planning on a cross between A/B and a STB...

acidify rootbark to pH2 in crockpot for a given time to pull alkaloids into sltn
dump entire sltn including powdered rb into vessel
basify to pH 14+
add appropriate amount of DCM
lightly agitate
drain off DCM from the bottom of vessel
couple of quick, very mildly basic washes with H2O
evap



Swim is looking for full spectrum of alkaloids and will only recrystalize final product with warm heptane if he cant get the vapped DCM to solidify.


Unless the powdered rootbark suspended in the aqueous sltn falls down into the DCM layer, swim doesnt see where filtering would be nessisary during any point of this extraction.

If it does.... that would suck big hairy ones.

One method SWIM's seen used is to do it in a 5gal bucket, tilt the bucket about 45 degrees, and pipette out of the bottom corner of the bucket. SWIY'll get nearly all of the DCM this way, and any extra bits of aqueous solution or MHRB powdered could easily be filtered out of the collected DCM. A kitchen strainer could be utilized to contain or fish-out most of the large chunks so as to not clog your pipette. A good pipette for this could be a rubber bulb-type nasal aspirator (for infants) fitted tightly to a vinyl tube of any desired length.

SWIM doesn't believe that solid crystals will be obtained in this way, considering the vast spectrum of materials it'll pull. SWIY'll probably have to do an N-oxide conversion, since the N-oxides won't crystallize. An easy way to retrieve all the desired alkaloids would be through FASA Method, though it won't precipitate the n-oxides, so a conversion will still have to be performed.
