There is no such thing as 4% paraformaldehyde. Nobody can sell or
us= e such a non-substance! See Histonet archives passim ad
nauseam.= (That's how the ancient Romans
said, in 3 words,= "on and on, until you want to
vomit". Latin is concise= !) 4%
formaldehyde is a real solution, and = one of the ways of making the
solution is to heat 40 grammes of = paraformaldehyde in a
litre of water, with an alkaline catalyst to sp= eed up the
hydrolysis. Paraformaldehyde exists only as a solid substan= ce,
which is insoluble in water. All this has been in all the textbooks and manuals for 40+ years.
