I’m pricing out a small “home size” SPD for experimenting with hemp derived CBD distillation and maybe making some personal hash. I’ve read a ton on here about the topic and wanted to get some feedback on what I am considering.
I am thinking of going with a 2L boiling flask. Is there a downside, besides increased cost, to going with a 5L instead? I have read that people recommend filling half of the BF volume with oil, but is it bad to go lower, i.e. run 1000 mL in a 5L flask?
The next thing I am on the fence about is the glass/mantle/tubing/stands - is there a benefit besides customer support and simplicity to going with a kit from someone like @LabSociety or @goldleaf_scientific? The prices for 2L kits are around $7k, which seems expensive for what is provided. In my work lab (non-cannabis), I buy cheap glass from eBay semi-frequently, but we don’t do anything with high vacuum/pressure so I haven’t had issues with it… from what I’ve read on here, cheap glass seems to be potentially dangerous with SPD. Are those kits a significant improvement over something like this or just piecing together your own glass?
For the vacuum pump, I intend to get something overkill (like a used Edwards E2M28) so that when I scale up to WFE (or similar), my pump will still be useful. Will this be a problem with a small 2L setup? Do I need a roughing pump, or can I successfully use just this pump?
Finally, for what I am trying to do (not huge volumes, home stuff lol), which components in an SPD setup would you go cheap on and what should I look for quality?
I’m just gonna use a sous-vide cooker, 5 gallon bucket, and an aquarium pump for heating the condenser… lab society actually sells that setup (at a pretty hilarious markup) so I am assuming it will work.
Thanks, I look forward to your input!
