Better Flange SPD - Stainless Steel Short path systems

Fancy? I thought I was speaking in reneck engineering tongues.

I do like to fuck around with some shade tree mekanik work, but these days I got so many damn projects going on that I’m leery of starting new ones!

@AlexSiegel How much terpene work have you done with this SS system? How would you rate it, overall, for recovering terpene profiles from cured or live resin?

The steel system is fantastic for terpenes. I have glass cold trap options and a steel option which both work great with dry ice.

Does this mean you have done extensive terpene work with this SS system?

With respect to terpenes, what is the greatest weakness of this SS system?

Research has been enough to know that the greatest limitation is the quality of the input material. As input quality goes down yield and speed go down too.

The best part about using steel is you can easily design your system around your specific material. Second best part is that steel gets very cold faster than some of the thick glass traps on the market.

The greatest weakness of the system depends on your configuration. The steel isn’t see-through so I would probably say that. In most cases like this seeing the trap isn’t fully necessary

Dozens of experiments complete.

Most recently I’ve put together a system to show to @Waxplug1 this Friday. I did a recovery experiment and recovered about 95% of input terpenes (1L recovered in 1-2 hours)

Would love to hear feedback (re terpenes) from @Waxplug1 after Friday.

@AlexSiegel Does it have enough “stirring power” (in the boiling flask) to aid terpene distillation from viscous crude? Would a durable overhead stirrer/homogenizer into the boiling flask be worth the non-trivial added expense? This would require a third neck on the boiling flask, obviously. Your thoughts?

I’m my experience most of the mantles on the market work fine. I aim for at least 300rpm with a relatively big stir bar. Any more than that is fairly trivial or counterproductive if the stir bar is big enough

Nice shaft bro! I really want that thing but first have to justify its utility. It would obviously produce higher shear than the stir bar, but would it improve the flow rate or separation of fractions? It would definitely have to be run fairly slow, I’d imagine.

I mix all my disty and vape formulations with an overhead mixer. Don’t even use stir bars.

The overhead is needed when u attach a diffusion pump to your setup and start distilling below 10C on the mantle.
Stir bars arent going to work for thick cold concentrate, and pulling terps with a lower mantle temp almost always works better than higher temp quick seperation

I bet the big versions of those cost about as much as a new civic.

Yeah, I haven’t enquired…

Knowing they exist gives me hope…knowing how much they cost would crush that hope. :shushing_face:

Today I had the privilege of operating this system in @Waxplug1’s lab. We ran a 2L system with 400mL of HTE loaded. We used a 4cfm vacuum pump for the full run which took a few hours for the terps and cannabinoids to finish

How convenient! And how??
