since tumbling of the tissue seems to be ok (=switching the orientation of the electrical field) has anyone tried ac instead of dc?
and i don't mean plugging the connectors into the wall socket, lower voltage, and maybe lower frequency too - what do people think? or maybe just a switching dc current?
i've understood that ac electrolysis of water can result in explosions because oxygen and hydrogen is produced at the same place, but with a high buffer flow rate i guess it should work (i've tried 20V ac/50hz with about 5L/min - no bubbles at all actually - but i don't dare make a real test and leave the setup on without a flow switch that kills the current if the buffer circulation stops..)
anyone tried something along this line?
