Harm Reduction Where can I get micron filters?

So the guy I bought 5 microns from off ebay says the only .20um he has are for oil based solutions only and won't work for water, he said he would look around to see if he had and .20s meant for water based solution and I told him if he can't find any to give me the .45s. I have never heard of this, are there different types of microns for different solutions and will an "oil .20" really not work with water? It's just a filter, what could be the difference?


How much of a difference is there between .45s and .20s?

There are many different membrane types. The there are 3 main types that are suitible for filtering water soluble drugs:

1. PES (Polyethersulfone) ~ Best
2. PVDF (Polyvinylidene difluoride) ~ Better
3. Nylon ~ Good

All three of these membrane types are HYDROPHILIC

Sterile 0.2 Micron filters are the most suitible, although I have some Sterile 0.1 Micron filters that work very well but tend to be more expensive.

If filtering pills, ALWAYS prefilter through tightly rolled cotton first to avoid clogging the Wheel filter. I find the cotton packed syringe method to be the best.
 
I went on the net and they were $900 for 12. I can get a sports coat for that price, made in italy. And I think they havesomthing better then the .2's .75's I believe.

Micron filters are not that expensive...at least not the ones I use.

The Whatman 0.2 PVDF micron filters are roughly $5/each on GPZ.

Is there a reason you think the PES > PVDF? I have only used the PVDF ones, and they work 100% fine.

I guess depending on what pill you use you might want to pre-filter, but for me Suboxone didn't need to be pre-filtered at all.
 
If PES filters really are better than PVDF this site sells 100ct 13mm 0.22um PES filters for $147.30 and 100ct 25mm 0.22um PES filters for $191.80 which is $1.47 and $1.91 each respectively.

If we could get 4 people to each pay $50 for 25 that we would be a good deal. I'm in.

Edit: They also have PVDF filters for $71 and $111 per 100ct for 13mm and 25mm which would only be $1.11 each or like $30 per person for 25.

PES (Polyethersulfone) Membranes have low protein binding characteristics and are better suited for use with Aqueous solutions.

This leads me to believe in theory that less of the drug would be bound up in the membrane and any remaining would be easier to flush out.

Now mind you the amount would be so miniscule that it really wouldn't matter I guess.

I as well have used PVDF in the past and they seemed to work great as well.

OK, as long as the amount is "miniscule". I run 3 pills through 1 micron filter and it lasts me roughly 3-4 weeks for 2 people, so whatever I'm losing isn't too important IMO. :) Thanks for the clarification though.

These are not Sterile!

Please make sure you buy sterile micron filters! Thanks for pointing that out, gibby.
 
I was reading this in another thread, sounded like an interesting idea for people who are going to inject pills with no micron access.

Incredible. We've got such an abundant amount of very wise people on bluelight.

This is the only way I'm ever shooting any type of pill, whatever pill it may be.

It may take the color out of some heroin if it were to be filtered with this method,

but It would reduce the amount of particles and other unwanted adulterants.

Depending on the quality of your diesel =D
 
I'm going to get my girlfriend to do this filtering method with her suboxone dose if she insists on shooting it without micron filters, I've told her about the case reports of limb amputation ect.
 
I just tried the method above and it works great. Time consuming but I did it twice to filter 75mg adderrall from an opaque oragne solution to a clear one with only a hint of orange. I know it's not perfect but it gets the job done and is the clearest I've ever gotten adderall (20x better than sucking through cotton balls with a needle (but that is still a first step to filter the big gunk and I clogged one needle at first and snapped the plunger trying to clear it). I can see all the particulates and gunk caught in the cottons and filter material I pulled out of the syringe. It also puts old syringes to use. I highly recommend this as a harm reduction procedure for anyone that is going to IV pills since microns are so hard to get and most people will jut use a cotton ball. This works very well and is the next safest thing. You just have to be patient with the process. I'm sure there are other filter materials that could make this work even better.

IVing pills is never safe, but if you are going to do it use this method. I should have taken before and after pics of the process and I will if I do it again. Wow I feel the amphetamines taking hold (I IVed half, still have another shot), anyone know the oral bioavailability of dextro and l amphetamines orally so I can compare this to an oral dose? The most I've snorted/swallowed was 120mg in a couple hours.


I've always been curious about adderal IV, which kind of pill, are they the

ovular shape round instant-release, or the capsules with the orange beads?

I'm, assuming they're the tablet form? They would seem much more soluble in water (no heat of course):)

I've got access to the 20mg instant release orange colored ovals, I've always been super curious about booting one but I never wanted to drop one in water and try, and end up wasting it because I couldn't inject.
 
Where indeed? Pls Advise!

I cannot find ANY place to buy these filters now... GPZ is out of them. Any suggestions? Sry to post this in 2 threads ...just getting a bit anxious here. Running out of stuff sux big time!! -Jaz

Try talking to Captain.Heroin.....he, in my opinion, would be your best source for info on this subject. Try PM'ing him. I know hes helped me out a great deal the past few weeks.
 
Thanks JB.... I concur the capt is a good man. Even capts run out of extra supplies occasionally. Any other suggestions? Thanks again -Jaz
 
I managed to find some lying around at work, but the packaging says non sterile. Should these be avoided? Or should I do something like run some ethanol through them then let them dry or filter water after that?

I use the non-sterile ones. Sterile micron filters refers to ones that are individually packaged.

You can see a picture of each in the Micron Filtering Mega Thread.
 
^ Thanks Captain, I plan on injecting some roxies today and was pondering on using them to do so. The nonsterile ones I have are individually packaged though. Think it would still be safe to use them? Or avoid them?

It would certainly be safer than injecting without them!

Whoa, really? That must mean they weren't γ-irradiated then? I imagined that if they bothered to individually wrap them, they would be γ-irradiated.

I assume they should be fine to use. I would just run sterile or bacteriostatic water through the filter first, and/or to rub isopropanol on the outside of the male end of the micron filter.

Either way, you definitely want to pre-filter with cotton. I'm not sure if you were or were not planning on doing that, but it is definitely recommended for anything like that. :)

Yes; the only time using a micron filter could hurt you, is if it is already used, and has begun to grow a fine particle mold, or even bacteria on the male side of a micron filter. Or, otherwise exposed to such a thing.

If someone theoretically used a micron filter to filter out their blood, then any blood borne diseases they may have would also contaminate the micron filter. However, I imagine if you are using a micron filter, this sort of thing wouldn't be likely to happen to you whatsoever.
