Hello ~ Wondering about the minimum size of Separatory Funnel needed for a 100g MH extraction...500ml? 1000? Thanks in advance...  My avatar is a detail from one of my paintings 'The End Is Insight' 1997

I use a 500ml funnel. "You cannot see Me with your normal eyes, therefore I give you divine eyes with which to behold the Power of My Yoga."
Bhagavad Gita, chapter 11, The Universal Form, verse 8

100g bark will need at least 750ml liquid....so get 1000 Really no need for a sep funnel..just overkill (unless your really into chemistry) You will also find that powdered bark mix will clog your funnel badly and frustrate the hell out of you. Just use a glass drinks bottle (1 litre) or a large pickle jar...(save your money for bark supplies) Please do not PM tek related questions Reserve the right to change your mind at any given moment.

^ I disagree with poster above. Separatory funnels are very useful if you're doing extractions in general, and you should NOT use it if you're doing an STB. You should use it for A/Bs and acqueous washings/saltings. In those cases, there is no powdered bark clogging the funnel. Also, how do you suppose to separate layers with a large pickle jar? And using plastic bottles together with anything other than water-based things is not a good idea. Check this for more info: https://www.dmt-nexus.me...aspx?g=posts&t=26324Re size, I'd say go bigger, it's better to have it a bit bigger than necessary than having it too small, so better go for at least 1l one IMO

Re size, I'd say go bigger, it's better to have it a bit bigger than necessary than having it too small, so better go for at last 1l one IMO Agreed... I should have mentioned STB..my bad! A/B...sep funnel...great idea Re: Glass bottle/pickle jar seps (1 litre size) are with turkey baster or pipette...personally never had an issue with this method.

Thank you, Gentlemen...I appreciate your input... My avatar is a detail from one of my paintings 'The End Is Insight' 1997

If you are planning to work with 100g+ of MHRB, I would suggest to go for a larger sep.funnel.
I myself use a 1000ml funnel when working with around 50g-70g of the bark...
(Also don´t forget that you can reduce the amount of the liquid by evaporating /heat-trreating/ it down, but in this case please be very careful with flamable chemicals around)

It very much depends on how much you extract and how much you like to reduce to. I like to extract 250–300g MHRB at a time, and I reduce to around 200mL/100g bark, with ~60mL non-polar solvent per pull. I got a 1L funnel, I would like a smaller one as well, maybe 250mL for smaller jobs like washing.

Gonna go ahead and bump this thread. Kash's mescaline tek works with 100g of cactus and the pulls are from a reduced amount of 500ml total. I can't see this being a problem with MHRB at all. Let's find out eh ? I'll post results probably next week. Art Van D'lay wrote:Smoalk. It. And. See.

I use a 1000ml funnel with spectacular results. It really helps me to control what goes into my decanting jar and what stays behind. I would go 1000ml if you can, 2000ml is rare to find but if you can find one, GRAB IT! "We speak of Time and Mind, which do not easily yield to catagories. We separate past and future and find that Time is an amalgam of both. We separate good and evil and find that Mind is an amalgam of both. To understand, we must grasp the whole." -Isaac Asimov
"You will not be punished for your anger, you will be punished by your anger." -Buddha
"I must not fear. Fear is the mind killer. Fear is the little death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when my fear is gone I will turn and face fear's path, and only I will remain." -Paul Atreides, while being tested with the Gom Jabbar by the Reverend Mother Gaius Helen Mohiam

Agree that bigger funnels are more joy for doing an actual extraction in. 500ml did indeed work but the reducing was quite a pain. Art Van D'lay wrote:Smoalk. It. And. See.

Go big or go home. 2000mL. Expect nothing, Receive everything.

Yes, it's more comfortable to go for a big funnel. 2000 ML is a good size. Running mescaline extraction or mimosa/acacia will be much more easy. Smell like tea n,n spirit !
Toke the toke, and walk the walk !

But isn't a bit of a pain to separate the top fraction (like the top layer holding the freebases) using an large separatory funnel? I personally find it quite messy and not as easy-as-advertised. I also get the impression that people often think that sep funnels will greatly ease their extractions without thinking too much about how they plan on using it or whether it will actually make things easier. If your solvent rises to the top (naphthas, aromatics and terpene-based solvents) then siphoning off is far more practical in my opinion. A sep funnel will really not make things easier in this situation. Why? 1. As you remove the bottom basic aqueous layer with a view to keep the top (solvent) the basic aqueous layer will be smearing the sides of the sep funnel. In the end (and unless you take extra steps like adding more water to clean off the smears, then separate again etc, uuugh, the pain!) you will have a far more suboptimal and dirty separation than siphoning the top layer. 2. Moving around by transferring the basic layer does not sit well with my idea of safety. Really, why get into the situation of moving around from vessel to vessel a caustic solution? Safety-wise, makes little sense. Just leave it be in one constant container. However, if the solvent sinks (like in halogenated solvents e.g. DCM) then the true potential of the sep funnel is realised. I find that a small sep funnel (250-500ml) is excellent for salting naphthas, aromatics and terpene-based solvents. Instantly practical because in such cases the bottom aqueous layer with the salted alkaloids is collected. Cactus extraction definitely benefits from a small sep funnel to assist with the saltings, and for said job, no way a large sep funnel is necessary. Need to calculate between salts and freebases?
