Care to explain how you use that capillary?
I wonder how you get material in and not let oil get to it. Just a minor detail I guess but just wondering.
I still think you assume too much equipment although I am not sure how expensive an infrared temp gun is. Ghetto acid/base is a pain in the ass and I was relieved to get my first separatory funnel for extraction, but you can still do it with extremely cheap and well-available stuff. A proper thermometer itself is an investment, it needs to go above ambient temperatures. With that money I'd consider a funnel instead.
I have a better idea. The freebase melts at 75C (158F), the HCl melts at 145C (293F) so the boiling point of water is well inbetween.
So forget the thermometer, just get some water to the boiling point and get something like a test-tube holding some of your product and hold it in there. I don't have to tell you to use some ovenmits, you don't want to get burned... if it's the HCl it will not melt, if it's the freebase it will.
Takes very little time and effort. If it's sold as the HCl then I wouldn't think about buying stuff to test if that's not actually a lie if you don't have to. Check it the easy way and do the acid-base conversion. Consider getting a funnel if you plan to mess with shit in the future, but I hear they are not always as easy to get and insanely expensive new. In my country I found a second-hand lab equip vendor. If it's for one time only just use a turkey baster.
Fractal fountain, I mentioned the melting point of the 5-MeO-DMT HCl salt but you probably should go above the boiling point. I imagine it's a good bit higher than the melting point for the salt and you should expect pyrolysis and therefore harsh smoke. I am assuming here, because salts are generally much more heat-stable than their freebase counterparts. Which is the reason you can't smoke many drugs in salt form that easily because a good portion of it burns (again: not good for the lungs or 'potency'). But it's not always impossible or so inefficient you should forget it immediately... IIRC the salt of DPT is actually quite smokable, check the Big & Dandy DPT thread and search for salt?
Like I already said about devices like the vulcano: beware of messing up your machine with inefficient vaporization i.e. melting a freebase but not boiling it soon after, yielding a liquid. Pyrolysis products (tarry shit) should be okay to clean out of your vulcano I imagine, though still not a joy for life.
