Yes, I get that, and the outside matters too.  What outside dim. are the 1mm cuvettes?

Here's a scope photo at 1ms/div.  (the last one was at 0.5ms/div time -- my mistake earlier)

The photo is just like I envisioned, (and sketched), this -- a rough DAC for HV.

when used on non-salty suspensions, it might be good to have a resistor that can be switched in
fast by some way that does not blow up transistors so as to cut the volts off faster than the RC decay you see in the photo,
