Fixative solution reagent Formalin B

for histologyliquid

FormalinB is a fixation solution suitable for the preparation of histological specimens. It consists of 40% formaldehyde (4% w/w), diluted in distilled water at a 1/10 ratio and buffered to a pH 7.2-7.4. This pH allows a faster fixation because it stabilizes the balance between formaldehyde available for the fixation reaction and methylene glycol (more stable product that does not bind to proteins).
