Good luck with your experiment out there. If I start my DIY NETs, the first batch will be American Spirits too, possibly the organic one.
American Spirit baked or actually broiled yielded 50ml of very concentrated tasty tobacco. Problem is, since I had to use a high VG in mixing the final e-juice, I also added 15% water. Now it tastes like smoking very tasty but wet cigarettes. Lol.
I think I'll play with this juice and add some home extracted coffee and some caramel flavoring from VZ.
Overall, it was a big success, on the first try, thanks to all of you who did the research.

Hey Chuck ~
I didn't catch how much pg/vg you started with to yield that 50 ml. Just wondering if the broil dried the perique and allowed it to absorb more liquid.
I did an American Spirit Perique extraction last week and just pulled a ml to drip. I'm getting a very complex spice note but no solid tobacco bottom end. Of course it needs some time but it tastes like a winner.
I used 150 ml pg/vg at 50/50 per 15 gm of tobacco which yields ~115 ml extract. I'll probably do a 50% extract for the final mix.

hi, all started reading this thread and I love it ... I am going to try a different method. I am going to cold extract under vacuum
1. 1/4 pound of black cav. from bulk from my local pipe shop as I have tried the plume rooms candied cav. and I like it.
2. 2 oz of PGA then 8 oz PG mixed and mashed in a glass bowl for 30 min with a gloved hand then put in to a vacuum bag
I have a ARY brand VP 112 chamber style vacuum sealing machine.. then I am going to let it sit for 2 to 4 weeks
3. I am going to buy a vacuum filter set up from a local lab equipment shop along with some lab filter paper.Buy Syringe Filters | Membrane Filters | Filter Paper | Tisch Filters
4. I am also going to buy filter screen from McMaster-Carr
I will see how it turns out.. I have the black cav. in the bag taking a nap for the next 2 to 4 week or until I get tired of waiting

Interesting. Usually the very low pressure ("vacuum") is sustained with a pump, such as freezing ice at low pressure to remove bubbles. What you're saying is you're going to extract without air, but your PGA/VG/tobacco mixture will not be under vacuum, unless you keep that pump running the whole time. Did I understand correctly?
I have a VacMaster - VP112 Vacuum Packaging Chamber Machine the tobacco/PG/PGA mix is in a vacuum sealed bag..
the first filtering was done with a wire kitchen strainer and cotton balls shoved into a syringe. but so far so good
Haven't read all of this thread yet but if anyone knows how to make your own nic juice from tobacco leaves can you please point me in the right direction. (without the addition of previously purchased nic juices) Thanks guys.
I'm finding that unbleached coffee filters actually do quite well in removing all (visible) particulate and leaving a translucent liquid. Double or triple filtering doesn't seem to have a significant effect, yet.

Make it like you're steeping tea, except use glycol instead of water.
- Get a quarter cup (or less) of rolling tobacco, pipe tobacco, or a finely chopped cigar. The less added sugar, the better.
- Put the dry tobacco in a glass jar or Pyrex measuring cup
- Heat 75-80mL (3oz) of propylene glycol (PG) to 150F or so
- Pour the warm PG over the loose tobacco
- (optional) heat the glass jar / measuring cup with tobacco/PG mixture in a double boiler (or in a saucepan water bath) on low heat
- let the mixture stand / steep for a minimum of four hours. Some say days. YMMV
- filter the loose tobacco out of the PG, using various methods described in this thread
I received my order of syringe filters, but it was a no-go. I tried them with my coffee extracts, since my tobacco extracts are more valuable to me and have already proven themselves to be not only delicious, but moderate in their effect on coils.
The .22um pore size is way, way too small to filter any of my vaping extracts. Load the syringe with extract to be filtered, screw the filter onto the leur lok, press the plunger, the filter fills up with extract, and that's the end. Nothing comes out, no matter how hard or how long the syringe plunger is pressed.
I tried filling the syringe with water to see if the filters might be defective. Upon pressing the plunger, water filled up the filter and went right through with moderate pressure, flowing out the exit spout exactly as it should, so I assume the filters are OK. The other common size for these filters is .45um, but I'm not going to buy more just to see if those might work.
I tried stuffing cotton rounds into the 60ml syringe as pepperman mentioned in his post above, and the extract that resulted (with considerable effort) from that filtering method was indeed much more clear than the very dark twice-filtered extract I began with, but the clarifying was accompanied by extreme flavor loss. Afterwards I whipped up a 3ml bottle of juice using 15% of the clarified extract. To say that it was weak in flavor is an understatement, and what flavor there was didn't please me.
I don't know. Maybe I'll just stick with what I've got.

Bill, I got some lab filter paper to clean up my extracts. It looks much like thicker coffee filters but is flat so you must fold to make it into a funnel shape. Filters are available (Amazon) in various pore sizes, I got 11 and 6 micron. My tobaccos were very slow to filter through the 11 micron so I haven't tried the 6 yet but will next time I extract.
Eleven micron cellulose lab filter paper is not going to remove a whole lot more of the particulates than coffee filters, but on my stuff it did help. I think the 6 micron should produce a pretty clean result but may take a vacuum to pull it through.
Of the six tobaccos I've done in the crock pot, two are good, two will probably be used in blends, and two are meh. All are very dark and have a similar taste that I think comes from a little too much heat. My next attempts will be unheated soaks for a longer period.

There are also 1.2 micron filters :

Some people had good luck with those smaller pore filters with their NETs:

Perhaps the coffee comes out with larger particles.

Chinook,
Fascinating that some posters (or at least one) on the other thread are successfully using the 0.22 micron filters. I don't see how, really, given that the two filters I tried clogged completely the moment the extract liquid entered the filter.
I watched a couple instructional videos on YouTube about using lab syringe filters, and my procedure was correct---draw the liquid into the syringe, then attach the filter to the leur lok, then press the syringe plunger to expel the filtered liquid through the exit spout of the filter. The problem is viscosity. I tried using pure PG and VG with a syringe filter. PG can be pushed through a .22 micron filter, but only by applying great force on the syringe plunger, and even then the liquid comes out the filter exit spout only about one drop every four seconds. VG will not come through at all, no matter how much force is used on the plunger. If pure PG and VG don't work with syringe filters, then obviously extracts made with those bases won't work either.
And yes, I've read from numerous sources that additional filtering of natural tobacco extracts results in negligible flavor loss, but that wasn't my experience yesterday with the syringe stuffed with cotton rounds. Using my instant coffee extract, the flavor loss from that method was severe.
I feel no need to further filter my tobacco extracts. They're fine as they are (and yummy, by the way). The two-stage filtering I do (first through the woven nylon mesh filter of a large Melior French Press pot, then through a paper coffee filter in a Melitta cone) is adequate for my tobaccos. All I'm trying to do is clean up my instant coffee extracts so that they don't gunk up coils so quickly. The coffee extracts taste great; I just want juices made with them to vaporize more cleanly.
My abiding rule in vaping is, "If it isn't fun, don't do it." Making coffee extracts is beginning to approach the "not fun" zone, so maybe I'll stop messing with them.

Bill, sorry to hear that your filtering with the syringe and cotton balls did not work for you. I had let my mix steep in the vacuum bag for almost 2 weeks before I posted. the only NET I have every had to compare it with was the plume room candied cav. the process I used the say the least was long and drawn out.. i had to change cotton ball after every syringe full 4mls at a time for 90+ mls. i will be trying this again but with the lab vacuum filter system i have on order. i did not use any vg in my extraction and maybe the little PGA that i added to the PG helped with the thickness. i really like flavor i am getting from my black cav. NET thank you scarf and all the rest for all you have done.
pepperman,
Whatever works for us is good. So much of this is a trial-and-error learning curve.
Thinner viscosity makes filtering much easier. With my most recent coffee extracts, I used 25PG/75VG for one, all-VG for the other. They're both very thick. While I like the way VG carries the flavor and provides a natural sweetness, my next experiment with coffee may use PG cut with a little vodka.

billherbst,
It sounds like maybe the coffee extracts end up having more particles in them. Once you filter them out the flavor goes out with them too. When I make my morning coffee I grind it fine, but not powder, and then filter with a sieve three times. I also throw out the sediment at the bottom of the cup after each filtering. The coffee tastes great but has some residue in it like Turkish coffee... If I filter the same coffee using a coffee filter half of the flavor goes out too...
I'm really surprised though pure PG filtering problem through these filters. I agree that if you can't filter PG, your NETs won't either. Maybe the material of these filters do make a difference vs viscosity of a solution.

The other unknown is the quality of filters I bought. Not to bash either eBay or China, but with something like these filters, buying cheap (the filters I bought were one-third the price of similar filters on Amazon) is an act of faith. The filters are yellow plastic disks that appear the same as others I've seen from lab supplies sites, but are they constructed of the same materials? Who knows? At any rate, once burned, twice shy.
Water went through the filters just the same as on the instructional videos I watched on YouTube---coming out in a stream with little pressure on the syringe plunger. I was surprised and taken aback that the filters didn't work well at all with PG. The hand pressure required on the syringe plunger to force pure PG through the filters---drop by slow drop---was ridiculous and painful after a minute or two. And VG? Forget it.
Oh well, I've had numerous failures along the way during my three years of tinkering/modding/repairing vaping stuff---sometimes despite prolonged efforts. Remember blue foam? Syringe tanks? Plastic box mods that would break and need to be fixed every two weeks? Luckily, my successes have outweighed my failures, mostly because I eventually stop trying to turn the failures into successes and just move on to something else. I try my best to keep it fun and do what works.
