Used formalin, particularly from breast cases will retain components from
the tissue.  We see these as the non-recyclable by-product after used
formalin is recaptured.  Perhaps this explains, at least partially, this

Does formalin decrease the weight of tissue?  In surgery for breast
reductions the tissue removed is weighing > 400 grams.  After the addition
of formalin the lab is getting a weight that is 20 grams less.  The
balance/scales used have been compared and they only have 2-3 gram
diffrence.  What do you think??
