Many laboratories at UW use formalin solutions and paraformaldehyde solutions or solids as part of their research and clinical activities. It is commonly used in tissue fixing and preservation, and as an organic chemical reagent. The most widely used formaldehyde-containing chemical at UW is 10% neutral buffered (NB) formalin,
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. Paraformaldehyde (PFA) is actually polymerized formaldehyde Stainsfile - 10% Neutral buffered formalin Neutral buffered formalin, usually simply shortened to NBF, has become the standard fixative for use in a diagnostic setting.It is more effective than the simple formalin mixtures as the phosphate salts present make it unlikely that erythrocytes will be damaged, and the neutral pH inhibits the formation of formalin pigment.The phosphates will adjust the pH to about 7.0 as the "neutral" infers

The other option is to buy 10% neutral buffered Formalin (4% formaldehyde) from a scientific supply house, use it for 3-6 months and then discard it (as a hazardous material). There will be some methanol in this solution (typically 1-2%), but if used soon after purchase this should not be significant for most users.
