Hello Everywheredan. I am interested in high capacity solvent recovery systems that are bigger than rotovaps as well. I have been looking at True Steel’s falling film (Link below). They have a 15gal/hour and a 30gal/hour. They do not advertise a price but I would imagine its somewhere around $75,000 to $100,000. I also found an inferior version of this called the SprayVap by CES. The reason I say its inferior is it has a small collection flask and it is entirely made out of glass. If the main column breaks, which can happen from heat gradients, it stops the entire process and cost a lot of money to replace. Stainless steel is obviously more durable. I got a quote for the SprayVap at $115,000. Let me know if any of this is helpful to you. Has anyone else have experience with either of these machines?

ps: If you have a rotovap now and have not read Future’s “Optimizing your RotoVap” your missing out. Preheating the solution before adding it to the evaporation flask saved me a lot of time.
