First pull-out going on

End of the first purging











Once recollected with silicon pads and pressed between 'em

Inox-filter and part of the pyrex tube I'm using for extractions







Second pull-out. BHO was moved from PTFE sheet on a SilkPad of small dimensions. Good only for very small batch like 2 or 3 grams.

I'm using a 20mm PMMA A4 size panel cut with classic saw, so it's not clear on the sides. Laser saw would makes it clear on the sides but it doesn't affect anything, just looks better.

Connectors are made of a mixing pieces made for air compressor and I needed a turning lathe to make it working.
I also need an air-filter to mount on the air-intake to avoid any dust in the extract.
All connections have just a little PTFE on the thread and the Y connector is screwed up directly into the PMMA panel, so it has its own thread.







This at the end of the first purge




End of the second purge. Still some butane traces in it I guess, but it's pretty hard and smokes absolutely smooth with a good GreenPoison flavor.

I like to spray BHO directly into a PTFE sheet if no further winterization will be done. Very useful, as I really don't like to scrap it off from a pyrex dish for various reasons.

If further winterization will be done, PTFE is not used in the first extraction.




I also use silicon gloves to avoid cold hands when spraying. Very useful as I don't use a stand.
Pyrex tube is 55 cm long and 5,5cm wide. Can pack around 50 grams of dried trimmed leaves.




Critical trim, not the best one for BHO, but it has a strong skunky aroma and a strong high






Filling the tube

[noreason]

Filter on and ready to go




Pyrex and PTFE sheet...well it's not exactly pyrex but some kind of borosilicate made in France



Butane cans and tube ready. Noticed some more pression on Colibrì and some less for Clipper






Ice forming during and after extraction

[noreason]

Boiling butane just after the extraction






I did a mistake with PTFE sheet and had to transfer boiling butane into another ABS plastic box. Same effect, but I prefer pyrex anyway.







Some covering to avoid dust contamination from outdoor air. I try to avoid extracting on cold dry days, always outdoor trying to keep butane ppms low in the surroundings air.

Just after butane is gone










IR thermo

[noreason]

Purge starting just after the solvent is gone and bubbles stop directly on the ptfe sheet to increase its viscosity.
Once its viscosity reaches a certain point it can be easily removed from ptfe and collected/stored/purged more.

Still not purged, low viscosity





Purging and increasing viscosity




Giving some heat to decrease viscosity. I'm using cheap equipment in a DIY way, so I'm trying to work at very low temp. with a max of -29,85 inHg. At now I never let the extract go over 40/45 C (110-115F). Will run more and more to understand the tech and try to raise temp. to see what happens at different levels.




Just after the first purge I move the extract from ptfe on some silicone pads I bought just for this, and they're really useful! I would reccomend for this kind of things...by the way...does anyone knows if there is any side effects using silicone pads to store extraxts? Does it outgases or somehat?
