Paraformaldehydepure

(Polyoxymethylene)
(CH2O)nMr (30.0)nCAS [30525-89-4]

Paraformaldehyde is a cross-linking fixative used in histology, light and electron microscopy and flow cyrometry. It is changed to formaldehyde by heating and by adding small amount of sodium hydroxide.
When the samples are to be used in fluorescence studies, paraformaldehyde is recommended as fixative. In histology it is generally preferred over other fixatives as the others result in more silver grains on the tissues.
