Cleaning/purging concentrates?

[Darb]

I have some oil that tastes nasty. Maybe not purged properly. Maybe made with cheap chemicals.
I'm not sure if it's BHO or ISO wash.
Has anybody tried dissolving nasty oil in ISO and winterizing/filtering it to make it taste better?

Is nasty in that it grabbed too many nasties or that it still seems underpurgerd? If its an under purgered bho iso will clean it up fine. Acetone would also work. But if you're trying to actually winterize it may not help, that does remove waxes but if its nasty flavored it may be excess chlorophyll and/or other plant material, which would likely be absorbed again by another solvent.

Seems under purged. I'll give it a try.
Will post results.

Winterization isn't a solution for underpurged oil. If it's underpurged, I would gently warm the oil and purge it some more (vac it if you can).

I've winterized oil several times to remove impurities, mostly to clean up oil that buddered, and I've been very happy with the results.

If it's just underpurged than Iso will work fine as a chemical purge, just make sure to spread it thin. Acetone would also work and would not sacrifice an flavor, but acetone fumes are very toxic so if you can't use it in a good enviroment to deal with the fumes I would say use Iso.

How can you tell if the BHO is underpurged or not?I saw some bho at a friends house made from BlueDream. It had a greenish color to it, but also contained some black mixed throughout it. it tasted fine, but was kind of curious if it had not been purged properly or if it was just that someone mixed in all washes together for one lump sum of bho as opposed to separating the different washes/cycles for purity purposes. I tried to ask him what it was purged with, but he had gotten it from someone and he didn't know...

Vacuum purging is the best option. If you go to your local car store you can get vacuum pumps for break bleeding, and make a vacuum chamber out of a mason jar or something. Its the best way to purge.

Drop a small dab on some hot Ti... if it sparks and sputters then it's not fully purged.

I'm a big fan of vacuum purging, but I wouldn't personally use a mason jar. They are not designed to withstand a vacuum and can implode. (I'm really big on safety when it comes to BHO)

 

[CentiZen]

That is quite true; I myself use a VacuVin coffee saver as my vacuum chamber. The mason jar; I was just thinking about what was cheap and accessible for most people.

I used a thick glass latch type preserve jar that I drilled the lid with a ceramic bit and a slow drill as a chamber for a brake bleeder pump for two years without issue, but I do suggest others (along with mason jar users), at least tape up the glass exterior of the jar to prevent any flying loose glass should it actually implode & catching one's eye.

Thanks for the advice. I don't have any Ti at the moment. I have always used glass nails. Only been into concentrates for about 4months now, have 3 glass nail rigs have only broken one and It was my first nail. LHS has some vapor swing GonG attachments but they can't tell me what the swing is made of if its Ti or not...so I'm not chancing it. The bho doesn't spark though when I vape it on the nail. Like I said I'm kind of new still to oils, but I get my nail red hot then let it cool for like 3 seconds before dabbing, but no spark? Maybe it's just a mixed batch...oh well.

^^ it doesn't mater if it's Ti or glass. It's just about exposing the BHO to something hot enough to cause any residual butane to combust. Based on your results, it doesn't sound like the bad taste isn't butane. Hard to say if winterizing would improve the taste, but it might be worth a try.

@Centizen: those vacuvin chambers will implode, even when used as directed...cost me about 12gr of very nice oil this lesson i am using a second hand glass dessicator, can be found for about 40dollars.

I have experimented a bit yesterday with redissolving some buddered up bho into 94procent alcohol. After evaporation and another pul in the vac chamber to be sure it came out reallly nice...

Not sure what you are talking about, if there are black pieces and stuff in the oil then someone has not done his job correctly I guess a wash and filtering might take care of that...

What level of vacuum did you have in yours when it imploded? I usually stay at around 25Hg on mine and it seems fine. I purge extremely small amounts though, so if it does happen it won't be the end of the world. How thick is your dessicantor?

You can refine it even further by taking the budder that you disolved in ISO and putting it in the freezer for at least 4 hours, and then running it through a coffee filter. Putting the ISO mixture in the freezer will cause any remaining plant waxes to coagulate and solidify making them easy to remove via a filter.

It might be worth investing in a setup that can hit full vacuum. I only do small runs myself and am glad I bought a pump and chamber. I've found that on my first vac pull, the BHO will start to muffin at around 22-25hg, but after that initial pull, it requires a greater vacuum (at least 28hg) to really get the rest of the butane out. Not saying a full vacuum is necessary, just that it makes things quicker and easier.

same experience here. started with a vacuvin thing, but as stated, it imploded when using the pump that came with it. I did not have a nano meter at that point.

i believe the glass is 8mm thick. Am looking into getting one that is not made of glass, but jury is undecided on that for now Any suggestions? I am working with a deep vac pump so it should be made for that. I broke one glass dessicator by heating it up too much, did not implode but cracked, that is what they are designed to do. Still, feels strange using glass when working with these forces...

Any idea why the oil does not solidify so much anymore after cleaning it with alcohol? Maybe it should be left for a longer time, although there is no smell of alcohol in it anymore and it looks dabbelicious?

Any update on what happened with the OP?

I use a Bel-Art model 420430000 and a JFC 6905 vacuum pump. The chamber is plastic and I would definitely not heat it.... instead, I keep several ceramic tiles warmed to 150f and place the tile in the chamber and then set my oil on the tile.

I've noticed that any time I winterize my oil that the resulting product is more sap like.. I couldn't say for sure why that is, but I prefer sap, so I'm not going to complain

Thanks for the tips. The taste is good, can really taste the blue dream that was used. I just wasn't sure if the black in it meant bad purging or not. Like I said I think whoever made it probably just mixed 1st 2nd &3rd washes and so on into 1 lump batch. Just wanted other's insights. I appreciate everything though!

hey dreamtime, I was actually thinking bout doing the same next purge, heat up the ceramic tile that comes with the dessicator... will check out the chamber you mention, thx for the tip
