I have been running the hot condenser tek with varied success. The issue we are encountering is that by running the condenser over 120C, we get some vapor blowing past the collection flask and into the cold trap, so we turn the temp back down to 115-120. Has anyone else experienced this? Are people using a second drop down flask after the first one to catch any fly-by vapors?
Here is a photo of our setup, the flask under the dry ice cold trap is where I collect heads. It goes from there into a mechanical cold trap for any vapors that don’t collect. I’d love to be able to run this at 150C condenser for faster flow and better quality product!
