I don't think you want to leave it in the processor for 2 hours. Even at the embedding center, if someone can't come to help orient the tissue, we then take the cassettes out of the paraffin station and leave on a paper towel. Have done that for sometimes 2-3 days.

And if so what type of artifacts can one expect from tissue that was in the processor in molten paraffin for 2 hours after the processing was completed? Thanks so much.
