As a high school teacher I think there are a lot of benefits to your system in a classroom situation.
With the low voltage and the ability to use the GelGreen I feel you have minimized the safety issues while still providing a real life experience for the students. I also really like the carbon filaments that give your system more durability.
In high school, we don’t have a large block of time for labs like they do in college. The ability to set up your system quickly with a single plug is very appealing to me. I can set up the lab and just as importantly break it down in a short amount of time. The fact that students can see the results of the electrophoresis in just a few minutes is also ideal for a high school setting.
All in all, I think you have a winner with your system. I think that it will have a strong appeal to high school teachers that want to do gel electrophoresis in their class.
