All of you have to go in prison for 30 years. You are net bandits !
Please, give me all you juices. I will store them for you during your arresting.

Thanks for the reply! I'll be happy to experiment with a coagulant and see the results. Wont happen any time soon though, but I'll put it on the list. On a different note: I just extracted some Lane 1Q tobacco and ran your method. I seem to have overdone the filtration since I've lost a lot of product. Went from 60 grams to 28 grams, and it's now evaporating to 7 grams. In the jar that I'm using, the solution evaporates at a rate of 0.25 grams per hour - so it will be a few days before I transfer it over. The 2 micron filter seemed to do the job after freezing it, and doesn't look like I needed to do it more than once.
Very sorry, I meant aluminum sulfate not sulfide. I have to consult the literature again, but it's used in the initial stages of treating drinking water by making negatively charged organic sediments stick together and settle to the bottom so they can be filtered out (forms a sludge) - which is why I think it might work for our application. However, that's for water - not sure about ethanol.
I would imagine you wouldn't want to overdose the sulfate, in the same way you would want to evaporate ALL of the ISO alcohol. Who wants to volunteer to be the first person to vape it and see if there are any harmful side effects?
Another filtration method used in water treatment might be activated carbon filtration, which ADsorbs organics. But I believe you will have to lower the pH of the solution for it to work better (I'm hungover today so I can't remember everything. Turns out, everclear is useful for more than extractions).
This is what I want to find out. The chemicals used for wastewater treatment might be more appropriate for oils
Edit: Actually I think even wastewater uses activated carbon for removing oils. Though I'm pretty sure it will also remove the flavors that we want to extract in the first place.

Yes, that's an extremely high loss to filtering. I normally filter >100 grams at a time and usually lose around 15% to the filter gods much of it during the freeze filtering step (coffee filter). For the final filtering I use a filter holder which allows for a much smaller filter surface area therefore less is lost to filter absorption. The percentage lost actually increases with smaller batch sizes because the filters used will absorb the same amount regardless of how much extract is ran through them. I.E. I would lose the same 15 grams if processing a 60 gram extraction as I would when filtering a 120 gram extraction.
A small fan gently blowing air over the jar (lowest fan speed) really speeds the evaporation process. However, it might be best just to let time do the work so any oil that drops out of solution during evaporation (condensing) has time to coalesce.

Let us know when you're ready to test the extract. That way if you don't report back after sampling it we'll know it wasn't a good idea.
Today i have tried a another method. I have put ca. 8g tobacco with 70ml Ethanol and 70ml base (VG/PG/nicotine) in a jar. I will heat it at 50°C for 4 days. After this i will evaporate the ethanol and filter it.
The idea is not to make an extract and after this a juice. I will make a ready juice. Perhaps if i have luck, the flavour could be a little bit deeper and i could reduce the steeping time. The problem is, that i cant do the freeze filtering because it works only in ethanol.
Are there any coagulants which could help to reduce sugars ?

Hmm...so my extract is "done" at 10ml of PG flavor and it smells heavenly. However I'm having the same problem as another juice I've recovered, and that is a really bright note of something that I can only describe as burning hay/corn which overpowers the rest of the flavor.
I had an old extraction of burley, dark air cured, and virginia that I froze and filtered (it had been sitting around for over a year). The smell to it is brilliant. Deep, dark tobacco with chocolaty undertones, but when vaped all you can taste is that burnt hay/corn flavor! Are all NETs like this?

I have had to lower my wattage when vaping tobacco extracts since they contain organic material that burn more easily.
I also taste a bit of 'funkiness" in some of my NETS. Is that what you mean by hay/corn flavor?
I believe so, yes. My vape doesn't go below 3.0 volts/4.2 watts so I can't see if going lower would make much difference. It's a very strange flavor. Both juices smell very different, but have the same overpowering taste. Another way to describe it would be the smell of a packed gym when it caught on fire.
Someone suggested using a different setup to see if that makes a difference in taste. I usually vape at 10 watts using a 2.5 mm coil at 1.2 ohms. I might try going to a 3mm coil using rayon instead of cotton.
What kind of setup are you using?
For my main vape, right now I'm using the eVic with an Aspire Nautilus tank @ 1.8ohm. For testing the flavors I put them in blank cartomizers at 2.1ohm.
I think I recall someone saying that Virginia doesn't make a very good extract, and this seems to be the common denominator between these flavors.
I haven't seen that post, but come to think of it, they may be right. Much of my problem with taste comes from Virginias. Too bad coz I like the way they smoke

Such a shame. This Lane 1Q turned out smelling VERY similar to Tribeca or an RY4. Well, back to square one. I have some cigar filler and some dark air cured - I better get to it!
Taste is subjective and with that in mind; my perception is that Virginia tobacco provides a "higher" flavor note with a grassy hay/straw taste but not much depth (lacks a deeper darker tobacco flavor) if that makes any sense. A flue or smoke cured Virginia often trades a little of its grassy flavor for a darker smoky taste. Back when I smoked a pipe Lane 1Q was my all day smoke, I had more than a pound left when I converted to vaping NET. For my first attempts at extraction I used the 1Q I had on hand, didn't like the results. I tried extracting several other Lane tobaccos with similar results, I've yet to find one that yields an acceptable extracted flavor.
I have American Virginia Flu Cured, that I used in my older extract. Would you say it should be avoided altogether, or is there an upper acceptable limit - like maybe use no more than 10%?
Edit:
Here are the whole leaf tobacco's that I have on hand. I wonder what would happen if I mixed them ALL together.
1. American Virginia Flu Cured.
2. Dark Air Cured.
3. CT Broadleaf (Binder).
4. Aged Dominican Cigar Filler.
5. Burley.

Personally, I like a bit of Virginia in the mix. VaPers (Virginia, Perique blends) are some of my favorites. The problem is not all tobacco is created equally, it's the method of curing and casing that matters most and each brand/blend is different. An extract of a flue cured Virginia from Sutliff may taste nothing like an extract of a flue cured Virginia from McClelland. While both may be listed as "flue cured" the specific process used by different manufacturers can yield huge differences in extracted flavor. Another thing to consider is that with manufacturers like Cornell & Diehl, a tobacco like "Red Virginia" can be cured differently for each specific blend it's used in. The Red Virginia in Bayou Morning Flake tastes nothing like the Red Virginia in Red Carpet or Bayou Night. That's one of the reasons I extract so many different tobacco blends from so many different manufacturers.
I might also add that so far I've only liked around 5% of the different tobaccos/blends I've extracted. The rest of them ranged from blah to just OK, at least for my taste.
Another way to use VA might be to add just 2% to another flavor as an enhancement.
