Nitrogen Evaporator for Drying Out Samples

The protocols we use require drying out samples (similar to lyophilized samples) that are dissolved in varying solvents, including chloroform and methanol. We currently own two evaporators from Organomation. We use the older one to dry chloroform-dissolved samples and the newer one to dry out methanol-dissolved samples.
The instrument works as expected and the attached water bath also works perfectly, but buyers would have to couple the instrument themselves (which was no problem for me).
