So that all of the eluent will flow to the drain, and to make it easier to see what's going on.

The reason it is tilted to my understanding is so that solvent pours out of the chromatotron for collection.
When I first saw these I was very impressed. For small scale separations it seems more reasonable then cutting up window panes coating them with
silica and sticking them in flower vases.
I considered a DIY build but quickly ran into issues. Finding circular pieces of glass, plastics(and a lot of metals) isn't really as easy as I wished
it was. That bevel at the bottom of the inside of the device would be hard to reproduce without proper tools, unless someone has a trick? The motor
isn't of great importance at least in my opinion. Speed control could be accomplished with a very simple PWM circuit.
My biggest qualm with the design overall is basically the lag-time from the solvent moving from the top of the chromatogram housing to the bottom
spout.
The reason for the great expense to my understanding is probably the materials cost and not so much the assembly. Some of the models use front covers
use a huge disc of quartz glass.
