We have substituted Zinc Formalin for B5 for our BM bxs. I have a few
questions I hope someone can help me with.
1. We increased fixation time 1.5 times from the B5. Question: Is
there a maximum amount of time the bxs can stay in the ZF without
causing harm to the bx? If a BM Bx stays in Zinc Formalin overnight,
will that harm the cellular morphology?
2. Can Zinc Formalin be disposed of the same way we dispose of our 10%
NBF? The B5 had to be picked up for special disposal due to the mercury
content. Is there special handling for Zinc Formalin?
Thanks and have a great day!!!
