[Alt-photo] Re: Papers for Palladium

[Jeremy Moore]

I do citric acid followed by 2 baths of hypo mixed with EDTA. Watch out that your water bath is acidic - if it's basic it can lock in the ferric. That's why I go straight from the pot ox to citric acid.

I hate to keep harping on COT320, because Bob likes it and obviously has no problem-- and I'm sure other people do as well-- but that is the one paper that I had a heck of a time clearing.  Maybe it's my water over here.  But with both Arches and with the Revere, water baths and citric acid/water baths seem to be fine for clearing.  But I'm sure what you're doing now would work as well-- seems a little overkill-- but if it works for you . . .  :)
