Sr. Verde's: Concentrate Corner

St. Verde,

Fantastic thread. I have a question for you, though:

Have you considered using an aspirator as a vacuum? It has several advantages over an electrical pump

- it costs less than $20 to produce a vacuum of the 28" hg you are looking for
- if drained to the outside, it is safer than a standard vacuum pump because the butane is flushed outdoors rather than into the air
- there are no lubricants that can absorb the butane, creating a fire risk (particularly with a non-lab pump that could produce sparks)

In my (scant) lab experience, electric vacuum pumps are avoided for volitiles like butane. I know you have never had a problem, but there seems to me to be a risk in using a non-lab grade electric vacuum pump.

An aspirator sounds good on paper, but I'm not sure how well it would actually work. For instance, the constant pumping action from the electric pump is really what gets the butane out. I could bring it up to pressure at 29hg, and leave the oil there, but it wouldn't purge very well. However when you flip the switch on the electric pump it brings it up to pressure, and keeps pumping, and that really pulls the tane out the best.

Also this pump has been tested by other consumers to pull a 25 micron vacuum.

As far as the "danger". I let my oil sit out under the sun in warm water an hour before I scrape and purge. It gets most of the butane out, just not all of it. Also I change my vacuum oil once a month, I've purged up to 18g of oil with no problems.

What else do I need? I want some magical BHO

This is what I use.

I think it's pretty awesome. http://www.harborfreight.com/two-stage-3-cfm-air-vacuum-pump-66466.html

I've done like 15-20 separate purges with it and it's still working great. I also got a 2 year full warranty for $20.

A vacuum chamber and 1/4ID rubber vacuum tubing.
Then you need some tubes, screens, hose clamps, a pyrex pan, razor blades, parchment paper.

And your all aboard on the BHO train.

Not going to lie, purging with the vacuum pump is tricky, some basic understanding of high pressure systems is necessary so things literally don't blow up in your face. I was used to the hand pump to purge, once I started with the electric pump it's like I had to re learn how to purge well. A perfect purge with this system isn't first try, but was third times the charm for me.

Verde first off, excellent thread. I have a question on your setup. After you put the erl in the sun what type of vacuum container do you place it into to induce a vacuum? You mention not putting it into a container that will blow up. Where did you get it too? Also was looking at the vacuum units and 350 microns is = 0.350 mmHg = 0.007 psi. This is a very low vacuum.

Thx

/\ That post is for info on the chamber..

This is the electric pump I use: http://www.harborfreight.com/two-stage-3-cfm-air-vacuum-pump-66466.html

It's rated at 25 microns, and a few customers verified. However that measurement is directly off the pump, once you involve the vacuum chamber I'm sure you loose marginal pressure. This is why I say I purge at 28-29hg.

Here is a table:



Generally, anything above 26hg will purge your oil, although the higher the vacuum, the more violent/rapid, and better the purge you get.

What tubes & screens do you use sr? I currently have a small PVC pipe and use coffe filters but would like to upgrade.!

He uses the okief tube. 120 micron

Yessir this man is correct. I recommend okief all day, as a company, and as a product. They aren't cutting me any deals or endorsing me (yet ) but I still highly recommend them.

I'd recommend getting the extractor II with extra screens, and oil drams, and maybe an extra rubber cork or two. (they come in handy, especially the big amber ones!!)

The tubes are easy to clean, flawless in design, and I've never had any issue whatsoever. I feel safe blasting these tubes; I feel safe tightening the hose clamp around the metal tube as tight as I can possibly make it without damaging the tube or risking safety.

Line the pan. Teflon sheets also work.

I just ordered one looks great, would like to see pics of demo or something just to make sure I understand this right. You can shoot the butane directily on the Oil Slick, use it to purge and store. So basicly you never have to scrape or mess the erl?

So I just got my new 4g glass extractor.


I have been running a couple batches all day. The first batch I let dry out and kept very thin and it turned to a waxy powder(not a lot of pictures, smoked most of it while making the rest ... Well here are some pics of the results.


^very hard and brittle, can play with it and mold it. Too much heat melts it but a little heat on your dabber cuts it like butter(about 2gs)


^Some of the wax powder, next to a little ball of bubble hash. (sry about the picture) The powder melts into oil with and any hard heat.


1 Run of about 4.5 grams came out hard like a rock and shatters unless you use heat(this is my favorite)

Well time to show you some dabs and rips I guess
my rig
my dab(the shatter with the powder)
milk shot(cam fell while I was dabbing sorry guys I won't fail next time)

Halen Honey Hole...pretty fucking sweet!!!...100% Quartz, even the joint...was a little pricey tho...I don't see it lasting as long as Ti obviously but I like the simplicity and the no dicking with a dome factor.

thats cool, did you ever consider one of these?

Yeah I've seen those and HE's design as well...HE's design I don't know how I feel about the hot Ti directly on the joint of my $500 tube....and those ceramic adapter thingys...it's something I'd have to see in person to be sold on....have you used that type??? that's the K.O. nail right???

ive never used one just found it awhile back and yeah its KO nail
been very interested to see others opinions on it...
what i Dont know and dont have experience with is the thermal transfer of TI
eg, dont know how hot the bottom of nail will get from the top being torched all the time

My 18mm V2 gets hot enough to vaporize the reclaim in the male / male adapter when it's cooling down from some dabs.

The ceramic ones burn carpet garunteed. They fall out if ur not careful.

But anyways. dab wars!!!!

who would win? Ragin raver mike or the globlin?

I'm pretty confused, what are they fighting for again?

I need a motive, dammit.

first toke man, they battling it out for first toke!

So about those oil slicks can you extract right onto it?
