It must be. We changed almost everything else we could think of and indeed, new

As far as i can see (without any experience with manual sequencing) the
automated way if in this respect just like the manual way.

I will give it a try. It's a simple and cheap solution. There's nothing to
loose and everything to win.

That would destroy the sealing in the thermoplate but i can clean the surface
that comes in contact with the gel and the samples.

Thank for your help.
