You can pull -28.5" Hg vacuum using a faucet aspirator pump to save money on the pump part.

Yeah, they've been a good vendor for me and the customers that I sold equipment to. I prefer ethanol for extraction and winterization, using QWET below -50C. I get the lower temperatures using either dry ice or LN2. Thanks for the good thoughts and appreciation, but as you know, you can't...

They are part of a closed loop system. The solvent passes through the heat exchanger on the way from the storage tank and the column of material. There are also heat exchangers on the recovery side to lower the temperature of the stream for passive recovery or for pump exhaust.

What is your end use?

Thats a Erlenmeyer vacuum flask with a Buchner vacuum filter funnel, using a #1 Lab filter.

When I heated up hot pressed rosin, it still fizzed from CO2 release, so it wasn't fully decarboxylated. If you look at the decarboxylation curve for THC, you will note that decarboxylation is not instantaneous at temperature...

I purchase the 70/30 mix. I've used either dry ice and alcohol or LN2 to lower the temperature as I pass the LPG through either an emersion or a counter flow heat exchanger.

And now I don't get it either considering the faceplate. 580 KN is not equal to 100 MPa.

The gauge is in kilonewtons. Here is a KN to PSI converter link: https://www.unitconverters.net/pressure/kilonewton-square-meter-to-psi.htm

If you are going to extract indoors, you will also need an engineered NEMA 7, C1D1 facility. https://graywolfslair.com/index.php/8-essential-oil-safety/8-14-please-do-not-immolate-yourselves-extracting-bho-indoors

Some background for perspective: https://graywolfslair.com/index.php/15-diy-equipment/15-1-the-history-of-the-terpenator-according-to-gospel Unfortunately, because I build my own, I have limited experience testing others equipment, but lots of experience building and certifying equipment...

Yes, about 30%.

Locally I get it from Apis Labs in Eugene, OR, who delivers and ships. https://apis-labs.com/ My local contact is Jay Romano @ [email protected].

Easy to build your own and quite a range in design and prices to purchase. How much volume will you be running and what is your budget?

To yield a traditional "Live Resin" extract rife with terpenes, you will need to use a low boiling point nonpolar solvent like butane/propane. You can do it with a simple column but consider picking up a closed loop system for safety and to enable yourself to first distill out the Mystery oil...

Kool! Looks good!

And back to the original question, may we talk about yield? Even if you do use dry sieve or bubble techniques, you can't come close to harvesting the full potential without picking up excess plant material, sooooo unless you are willing to throw that semi-spent material away, you still need a...

I prefer 99.95% pure Instrument Grade and when I measured it I found it to be 99.99% pure. After predistillation it measured 99.998% pure with regard to molecules greater than C-4. Typically a 70:30 mix of n-Butane and n-Propane to extract below -50C, though we've used 50:50 mixes, and mixes...

Because Graywolf wasn't available when I opened my account here back in the hoary days of yore.
