The current link is now Self Healing Rubber Injection Ports (100 peices) 13mm Rubber Bottle Stoppers (Steam Sterilization safe) for Sealing 1/4 inch or 7mm opening
Which are injection ports for mason jars. Those are part of a setup to grow mushrooms or a few other things, they are not useful to people who inject drugs.
Maybe this one would be a better fit?
I'm using some carts I bought off amazon (lol) and that's exactly what I thought might be the culprit at first as well, however, I read in a few different places that even the legit CCell carts and other high end ones do the same thing with homemade oil. I want to buy some nice carts and test it but I'm worried it will be a waste of money. I can provide links to the equipment I use if it helps.
Carts (These were taken off amazon so here's a screenshot. It is a little suspicious that the item was removed)
edit: I should add that I've tried multiple different batteries, some high end with higher voltage and some weaker ones, all to the same effect. The batteries also do fine with normal distillate from normal carts, it's only the homemade ones that have darkening issues. The one I have right now is basically pitch black, for example.
edit2: I know I'm a moron for getting amazon carts I was really broke at the time lol
I'll contact them. I was honestly so let down with the regular I didn't bother up until now.
I use these filters : https://www.amazon.com/gp/aw/d/B074QM7VTW?psc=1&ref=ppx_pop_mob_b_asin_title
I'd heat up the oil before putting it in the syringe but the cold quickly coagulates the oil and makes it thick, which prompts me heating up the syringe by pouring boiling water on the outer plastic, rinse repeat with the hot water as the oil in the syringe cools rapidly and the rate it's filtering is mind numbingly slow. End result is not that much clearer liquid in terms of color, definitely not liquid enough. Though when I heat it up I barely see residual fatty lipids floating on top.
What are you referring to when you say melt the crystals? My first thought was fully decarbing, but then you said "not just decarb" how do I know for sure they are melted? The no bubbles during stirring after 4 hour of decarb? Or just waiting for the extract to properly cool every time I suspect no bubbles remain?
I've so much to learn Obi Wan..
