This station simple holds some tubes on top of the position 1 of the aqueous wheel.
In most of our experiments we used only one aqueous phase of TTAB at PH 13.
The code managing the dish filling working station is here: software/working_station/fill_petri_dish.py.
It simply normalizes the quantity given in the experiment description file (see software) and fills the dish with the given ratios of each aqueous phase given their associated pump and for the defined volume.
