Many university organic course laboratories use Liebig columns packed with glass beads. This is what I use, but I would like to know if there are better columns that can be used instead of this. I had a problem with this type of apparatuse before. The glass beads shot right through the $30 adapter and broke it. Of course, its my fault since I did not secure the glass beads with a copper scrub but I would like to avoid something like this from happening again so I would prefer to use a different and more efficient column. I know there are other types of columns such as the Vigreux column, Snyder column, and etc. So what is the best column to use for general fractional distillation?
