Hi everyone, As I read and was told, formalin pigment is seen as a dark precipitate under light microscope. I also read that you can see this via polarizing microscope as it is birifringent. I'm wondering: does it first need to be seen under the light microscope, and birifringence is just a confirmation? Or, can you see its birifringence without needing to see the precipitates under the light microscope?
With regards to 10% NBF, do you guys pH this fixative if it's commercially prepared? Is this always reliably neutral? Thank you for your time!
