Thanks for looking around! I already have a good selection of chemistry glass and am no stranger to doing home experiments. (I could probably use a good vacuum filter anyways and maybe I am just searching for an excuse to get one.) Distillation is an option for me, but it’ll be last resort. Still, having a few proper distillation pieces would go nice with my collection…
Some filter rigs I have seen are using small RO systems, but that seems like a pain to clean and those people probably need to filter a ton of IPA for it to be cost effective. Regardless, it is absolutely worth exploring more as setting up a filter loop would be awesome until it gets gummed up.
This looked promising as it is dealing with ethanol and plant extracts: youtu.be/VjxZVpGv_aM?si=5VFLYQkObCzUawbb … (This video specifically got me thinking about what could/couldn’t be filtered and is the root of this post.)
And absolutely, a multi-stage rinsing system is going to be needed if I scale up, which may be in the near future. Full context: I am studying and planning for a reverse engineering/prototyping business, so there could be a considerable amount of printing in my future and this is particular problem is part of the cost analysis.
