I bought a system that was supposed to be a 5 lb. machine. When it arrived, it had the collection vessel for the 10 lb., which was a fully-jacketed 12-in monster. When I asked, they said oops, loaded the wrong one on your rack. My plans are to add columns, so I’m thinking it’s a win. They send me the right tees and valves, all good.
I’ve made several runs now. Running one column leaves a third of it on the walls and a shallow puddle in that giant bowl (170-210g). It feels like I’m leaving a lot on the sidewalls. No sense in running less than 4 tubes, before tapping it at the bottom. That means mixing strains during R&D. I want a little more flexibility. I can add tubes, it’s small-batch runs that are robbed by the monster.
Then comes the wrestling match to break it down and clean it. It’s a fine film, but its everywhere inside a vessel that’s bigger than my head and almost too deep to reach all the way up inside to clean. It seems like using a backhoe to plant tulips.
Is there any reason I can’t swap in a smaller 6-8-inch diameter collection pot? Ideas or ones that work well for you? It’s a rack system with each of the columns feeding over to the collection pot. Would a smaller pot recover faster, waste less, and be easier to clean? I can’t see why not.
