(firestorm: "Cooling Mixtures", Newbee Forum)what does the Friedrichs condensor look like? Would it be the one with linear bubble shapes inside it?
The one with the bulbs in it is an Allihn condenser, it is no better than a a staright tube Liebig condenser. The Freidrich has a sort of cold finger in it that the vapour has to impinge on, much like the dewar condenser picture posted by SuNNySide except that in the Friedrichs the cooling finger is closed except for inlet and outlet hose connections. If you look at a well known general (not just scientific) auction site under Scientific Apparatus and search for Friedrich you should find a picture of one.
I'm thinking of getting a 400m Vigoreaux (sp?)
A Vigreux column is a fractionating column for fractional distillation. It is not intended to be used as a condenser, for example, it has no cooling water jacket.
