[Histonet] Dissolving precipitate in formalin?

[Conway, Carla]

Hello,

I have 4 bottles of formalin which contain white flakes of paraformaldehyde
precipitate. I tried to dissolve the flakes by heating to ~65 degrees C for
45 min (with stirring). Has anyone been successful in dissolving this type
of precipitate?

Thanks very much,

Carla
