Subject: [Histonet] formaldehyde concentration
I am using pure formaldehyde
I am using pure formaldehyde with no methanol and unbuffered as a first
fixative. It comes in concentrations from 20% to 4%. From my reading; 1)it
seems the higher strength penetrates faster ?. 2)4% is the minimum strength
to get good penetration ?.

Dear Histonet members,
I would like to evaluate our NBF and formaldehyde aliquots to ensure that
it is at 4%, 2% etc. I would guess I need an assay between 0 - 5%?
Does anyone know a quick chemical experiment to test this? I have access to
all common lab chemicals.
I can see that there are kits
