Paraformaldehyde, Formadehyde and Formalin | Duke Light Formaldehyde is CH 2 O, the simplest aldehyde. Formalin is the name for saturated (37%) formaldehyde solution. Thus, a protocol calling for 10% formalin is roughly equivalent to 4% formaldehyde. Beware though, that some solutions have methanol in them to stop polymerization but this could have a negative effect on your sample. Formalin Fixative - University of Surrey Making 10% Neutral Buffered Formalin from stock solutions . Where only a standard stock solution of formalin* is available it is typically 37-40% formaldehyde (a gas) in aqueous solution and unbuffered. To make a histological fixative from this we need a 10% solution** of this stock formalin i.e. 1 part of the stock formalin Buffered Formalin Concentrate Fixatives - Reagents & Solutions

Fixation (histology) - Wikipedia The most commonly used fixative in histology is formaldehyde. It is usually used as a 10% neutral buffered formalin (NBF), that is approx. 3.7%–4.0% formaldehyde in phosphate buffer, pH 7. Since formaldehyde is a gas at room temperature, formalin – formaldehyde gas dissolved in water (~37% w/v) – is used when making the former fixative.
