Medical Definition of Formalin Formalin: A 37% aqueous (water) solution of formaldehyde, a pungent gas, with the chemical formula HCHO, used as an antiseptic, disinfectant, and especially today as a fixative for histology (the study of tissues under the microscope).

Neutral buffered formalin, usually simply shortened to NBF, has become the standard fixative for use in a diagnostic setting. ... For thorough fixation the proteins in the tissue need to be crosslinked, but it is well known that simple formalin mixtures discolour tissues well before they crosslink the proteins.
