Sorry, but just too too much has pushed us’ns over the edge on open blasting!

I’m sorry to say that I just removed our instructions on how to do BHO extractions using an open tube, after us’n three SPR partners unanimously agreed that too many brothers and sisters are ignoring all warnings against indoor open blasting, and the havoc they are wreaking is causing us to all be painted with the same brush as sociopathic idiots.

I left the parts not relating to open blasting, including butane safety, which is applicable to both open and closed loop extraction.

There are ample sites demonstrating how to open blast, so ours is not needed.

Sorry it came to this!  I note it is always the few that ruin things for us’n masses, but don’t know how to fix it.

Domestic Butane

Whoop, whoop, lu lu lu lu lu lu lu lu lu, awhooooooooooooooooooooooooooooooooo!!!!!!!!1

Medical extractors looking for a domestic source of 99.5% Instrument grade n-Butane will be gladdened by the latest gas supplier to announce a domestic source at competitive prices, replete with Praxair tests and certifications.   99.99% scheduled next.

You have to buy to own your first LP5 (24lb) or FX1 (120lb) tank, and then continue to swap it out.

Free Open Source Dosage and Pricing Software!

Hee, hee, hee, here is a good idea at the right price!

Periodically brothers and sisters send us stuff to try out and comment on. Leblanc CNE is one whom just sent us some free open source software that they’ve written for calculating individual dosages, as well as software for establishing pricing, based on costs and markups.

The joy of both is that you can change any number and it will update the rest, so it makes it easy to also play, “What if?”

I think it’s cool, and suggested posting it on SPR for more people to try and provide feedback to, which they agreed to, so here it is folks:

First we have the dosing software:

Here is the pricing software:

Here is where to leave direct feedback to the fine mind that created the software and provided it for your whim and pleasure free:

Poisoning the well!

Joe and I have both spoken out against sub standard and unsafe extraction devices, but how about those suppliers whose marketing plaudits, include poisoning the well for their competition with exaggerations and untruths?

Suppliers with such a low opinion of their own product, that they don’t feel up to competing based on their own products attributes, so they make a concerted effort to shoot down the competitors product using a tapestry woven of truths, half truths, and untruths.

Joining MO in that regard, we now have Connoisseur Concentrates with Mr Extractor, whom paint their competitors as intentionally poisoning the public.

They present their machine as the safer alternative, yet publish a video demonstrating extracting indoors, with out a properly ventilated extraction enclosure, a never, under any circumstances NO NO.

If they are the safer alternative, what does that make the rest of us?

Compounding the egregious blunder, they also didn’t first vacuum the oxygen from the extractor before injecting the butane.  They instead floated the oxygen laden atmosphere out and burped it out into the room.

Please ask your local fire marshal’s views on how safe he thinks that is.

In point of fact their “safer” machine didn’t even have a vacuum connection for a pump, as do both the Tamisium and Lil Terp they present as inferior.

We touched swords on IC MAG forum, ( Drew left the field to avoid answering the questions listed below.

I see them germane to the question of whether Mr Extractor is indeed safer and ahead of the industry, or whether they are just a rip off of the Tamisium and Lil Terp, adding a glass sight glass unlikely to meet ANSI/ASME in this application.

Certainly the jackets are handier than buckets, but are they safer and what in Earth justifies the $6000 markup over the cost to assemble a Lil Terp?   Is it the attached jackets to avoid using buckets.

What justifies the added cost over the Tamisium TE-175 at about $1800?

The questions begging an answer, and being avoided, are as follows:

(1) A yes or no question. Do you have a ME PE stamped document certifying Mr Extractor to meet ANSI and ASME?

(1.1) May we see a copy?

(2) Now may we talk about finishing. Would you share with us how you recommend finishing the material from your recovery pot to meet current residual solvent standards?

(3) Do you have any reputable third party lab analysis of product demonstrating the common deposits of metal and PTFE piston ring material in extractions and if so, would you please share?

(4) I am most curious about your use of 9mm borosilicate tube for the extraction tube, which we too looked at because it is so obvious, but decided to not pursue it after considering the effect of shock sensitivity during sharp temperature gradients.

We even looked at having the glass coated inside and out with clear PTFE for the added safety, but decided it wasn’t a good idea to have a pressurized glass vessel with flammable gas inside.

Sort of along the same lines of why the gas station won’t fill your glass jug for you.

(4.1) That leads me to the subject of liability insurance. May we see a copy of your product liability policy and contact information to your carrier?

Drew also claims superior performance, but has failed to address the following observations:

1.0 The pumped system is considerably faster.

2.0 The pumped system evacuates the oxygen before injecting butane, so that there is never an explosive mixture.

2.1 Since Mr Extractor uses no vacuum, the passive system mixes the butane with atmosphere as it is injected and floats the explosive mixture out. It is vulnerable to ignition and explosion during that process.

3.0 The system is recovered to -22″ in a pumped system, so only 25% of its volume in vapor is lost.

3.1 100% of its volume in vapor is lost when opening a passive system.

4.0 An active system recovers most of the butane soaked into the material in the columns, by vacuuming to -22″Hg. The pumps are unable to achieve that level until most of the butane is gone.

The last 25% between -22″ Hg and -29″ Hg, is subsequently pumped off using a vacuum pump, so when the columns are opened, there is not an explosive mixture.

4.1 The passive system not only doesn’t recover the butane soaked into the material to the same levels as the active systems, but when opened the columns are definitely within explosive limits.

Because it leaves the butane in the material, losses are greater.

5.0 A pumped system can pass more fresh clean butane through the material faster, and in both directions, so ergo it extracts faster and more completely.

6.0 You can recover a pumped system recovery pot at 31.9F, so as to preserve more carboxylic acids and aromatics.

6.1 Even using dry ice, you are still using a hot water bath with the meds in it, utilizing passive techniques.

7.0 An active system easily pre-distills butane at 85F, to remove residuals including Pentane, which boils around 100F.

7.1 Recovery at 85F using a passive system takes much longer.

8.0 An active system offers more latitude for propane mixes.

DIY Rotary Evaporator by Siskiyou Sam

Hee, hee, hee, don’t you just love synergism?

I posted  a rotary evaporator design based on available sanitary spools at the time, but didn’t build it because better options were becoming available, and Siskiyou Sam took the challenge and built one of his own design.

He has consented to share, so here tis:

The Generic Terpenator Operators Manual

The Terpenator closed loop essential oil extraction system invented by Graywolf, was donated to public domain, insuring that it can never be patented and that the prices will stay in check.

As a result, the basic Terpenator design now has numerous manufacturers world-wide that copy or emulate it, though not builders are scrupulous, nor do all meet ANSI/ANSI design and build requirements. Because the industry is unregulated, that means caveat emptor.

This general guide is intended as a straw-man starting point, for a general instruction guide that can be used by all Terpenator design close loop system users, to select, assemble, test, and run their system.

I simply took a Mk IVB operating manual and reworded it, removing valve number reference and brand name hoopla, because it is about Terpenators in general, not a specific brand.

There will be some differences, as not all Terpenator style systems offered are bi-flow, nor do all offer dedicated column recovery, so if your system does not, skip those steps.

Many of the same issues apply to systems designed and built by others, but some are enough different that they will have their own unique operating criteria, so a separate thread dedicated to those systems may be called for.

Because the backup reference file is large, I will post it in multiple bits. I also encourage all operating Terpenator systems to take this opportunity to toss in their own thoughts and questions.
