Hi all,
I've been having really good success so far with Cyb's max ion tek. I'm looking to upgrade my equipment to make my process more efficient.
Does anyone have ideas for what I could use for the shake/pull step? I am processing 200-250g MHRB per batch and am getting about 3.5-4L of mixture by the time I get to the shake/pull step. I have been using a 6L sep funnel, which is functional but cumbersome.

So what I'd like is a large glass vessel that seals well enough for shaking, has a lid that won't have any reactions with the basified mixture, and has a fairly thin profile for easy pulling of the top layer.

Any ideas / suggestions are very welcome

Thanks!

4 l glass wine jug? Has handle and narrow neck for ease of decanting...

Just get 4 1litres bottles and and do them at the same time. Why make things difficult for yourself?

I use something very much like this.4.5L.

I would say your best bet would probably be to reduce your solution to a more manageable volume before basifying next time... 4L is a lot to deal with, I find that it's much easier to do pulls if I keep my solution under 1L. Or, like cyb said, divide it up into 4 parts. That's my opinion at least. I have never seen a 6000mL separatory funnel, that thing must be massive!

Although some may advise against it, I use a 4L HDPE Jug.
I`ve had some explosive experience in the past from too much pressure building in glasses vessels, and glass and basic solution exploding everywhere O_O.
This avoids the necessity for a Seperatory Funnel.
I simply make a small hole in a lid with small scissors, and fit plastic tubing inside the lid and feed it through until only a cm or less is visible in the inside of the vessel.
I then screw this lid onto the jug, then squeeze the liquid upwards.
This flows the naptha/NP solution up the jug, through the tubing, into my collection tray/container/what have you.
Works wonders for myself and friends.

It is highly recommended that people do not use any plastics for an extraction. Most of the nonpolar solvents that are commonly used in extractions (including VM&P naphtha) can and will degrade HDPE and other plastics, leaving undesirable impurities in the final product. Even if there seems to be no observable change to the naked eye, the solvent may still be contaminated. Glass is the safest material to use for an extraction vessel, as well as anything else used in the extraction that might come into contact with the nonpolar solvent. It is true that glass can break more easily, but this can be easily avoided by taking the proper precautions.

Personally, I would rather not vaporize plastic with my dimethyltryptamine.

I think this is actually the more difficult method because one large extraction vessel helps the get the NPS more saturated and limits the amount you need to use. This is assuming you have access to something large to extract from.

Personally I think STB/ATB Teks are better for smaller amounts of bark. If i were to do a 250g extraction I'd probably go a\b and just reduuce the acid boils to something managable prior to basing.

This is what you need!

I don't understand the reasoning here... If you have a 4L solution and you want to use 200mL NPS, I don't think it would be any different than having 4x 1L solutions and using 50mL NPS in each one. You would be using the same amount of NPS and it would be equally saturated in the two examples, right?

However, it is probably more time consuming to do pulls on 4 extraction vessels than it would be to do bigger pulls on one large extraction vessel. I still recommend reducing, but splitting it into four small vessels isn't a bad idea either.

Entheogenerator, I`d like to put that to the test.
I should be able to simply place straight naptha in my usual HDPE jug, shake it for several days, and then evaporate. If it dissolves any plastics, I would have some left from the evaporation, correct?
Can you see anything wrong with the methodology?
Please note: I am not advocating this method, I am simply for my own personal use.

Unfortunately, I do not have any official chemistry training or education. I can only relay the information that I have gathered here on the Nexus and on other websites, but I have confirmed the information regarding the reaction between solvents and various plastics with multiple other sources before accepting it to most likely be fact.

That being said, this test might prove that naphtha does not dissolve large, visible portions of plastic over a period of several days. But this still leaves the possibility that there are microscopic particles left behind after the naphtha has completely evaporated. Honestly, I don't have a clue what would happen if you were to preform this little experiment. Perhaps you will end up with visible clumps of plastic after the naphtha has evaporated. It certainly wouldn't hurt to find out.

But, like I said, I do not have any official chemistry training of education. Because of this, when I read multiple sources that say chemical x and chemical y can create an undesirable reaction, I tend to do anything in my power to keep chemical x from coming into contact with chemical y.

You may have seen me post this picture elsewhere on The Nexus, I often post it when someone is asking about using plastics for an extraction. Here is another link that seems to convey the same information:
