On a more lighter note - If you want to reduce noise further then I suggest replacing those copper electrodes in the picture with silver chloride ones and maintain optimum skin contact with a conductive gel maybe.

UK users would need a 50 hz filter in the software. I don't know if this could be configured in the software panel or if you have a script for this?

Good luck with the project and the testing BTW. I would help out but I'm really stuck for time, but it is something I will follow as I'm quite interested in these types of projects.
The filter cuts off everything below 50-60 herz. There is a filter configuration file that specifies the threshold. The conductance is not that big of a problem (I think) , I can't quite figure out what it is that scrambles the instrumental amplifier.
