When blotting minigels, we blot for approx. 1 h with both semi-dry and
tank blotting.

I don't think semi-dry blotting generates less heat. We transfer minigels
at a current of 0.3 A (approx. 15 V). We do it at room temperature, though.

BioRad uses metal electrodes, not graphite. If you are not careful with
them, they tend to corrode. However, our department has its unit since
more than five years and still use the first electrodes.
