Most of my working life I had the luxuries of house vacuum and coolant lines. That made the rotavap quick and easy to use. One lab building where I postdoc’d had house vacuum but didn’t want those stinky organic chemists hooking their vaps to them!I mean it doesn't do either one too well and they say a 2L rotovap is the biggest it can handle, for occasional use only, but that's why I thought it might work with the distillation set.
So we used those blue recirculators. House coolant was allowed us, so we didn’t have to use ice except to charge the pump. Fortunately the big ice machine was only one floor down.
The best feature of a rotavap is speed. Once you’re set up and turning, stand back and watch recovered solvent pour off the condenser. The rotating action also takes you much closer to dry than a static distillation.
