For Pt/Pd solutions 0.01 gram accuracy is highly suggested and necessary
if one expects reliable repeatability. The scale I use is the Ohaus
Cent-o-gram quad balance. This scale is availiable from Edmund

Aside from the price differential of this scale compared with electronic
scales of the same accuracy and tarr ability (offset weight of bottle)
consider that for alternative hand coated processes it seems more in
keeping to use a fine mechanical balance scale.
