Optimizing your RotoVap

I think im gonna go with something like this. Definitely gonna find something cheaper though.

The grey schedule 80 pipe overhead goes to our central chilled water plant which is 215 tons. It’s only a 1-1/2 pipe into the lab though so somewhere around 30-40 ton capacity split between this and the rest of the lab

Any pump is going to add heat to the working fluid, it’s an optimization. Typically centrifugal pumps are around 70% efficient (there’s a really wide range depending on a bunch of factors), which means 30% of the electrical draw of your pump might as well be a heater. Bigger pump means more heat but it also means better turbulent flow and delta-t which make for better heat transfer.

What would you suggest doing to counter the heat from the water pump?

Only two options there: smaller pump or more ice

The good news is that we have 24 feet to the bottom of the next floor above that drop ceiling. The bad news is that the floor is 18" thick concrete…

On another note for those who may be watching, we kinda goofed. The vapor holdup is insane. I think I’m going to spin the whole unit so the vapor feeds from the top of the condenser which should have been a very obvious thing to do. Oh well.

Off topic one sec, “use a warehouse”… If agricultural engineers were as smart as that statement, Bill Gate would never worry about cows and meat again. No one would. Js.

Vapor feeds from the bottom?

Plumb it so the pump isn’t in the water

It’s not in the water. It’s not a submersible.

Yep. It was stupid. I also probably could have eliminated the auxiliary receiving flask too. Oh well, lesson learned. Still rips

Take some more pics after you spin it to send vapor to the top, this is so dope.

I can’t help but say this man: your wallpaper reminds me of Garden State

Joking aside, that looks like a very suitable pump

Man I haven’t seen that movie in a grip! Might have to find it and watch it. I’m a little quirky like that so I can sympathize.
