List the disadvantages of using formalin as a fixative. - ️️1. rate of formalin fixation is slow, complete fixation takes several days. (adequate in 8hrs) 2. may cause dermatitis in some workers 3. unbuffered formalin in solutions can produce precipitates in tissues (esp. blood-rich tx) 4. concentrated formaldehyde can polymerize, forming paraformaldehyde, reducing working strength of solution and any formalin solution prepared from it. What solution would remove the precipitate forme...
