DIAGNOSTIC METHODS: Concentrations

What specific gravity zinc sulfate should be used for the flotation concentration procedure?

If the concentration is being performed on fresh stool, the specific gravity of the solution should be 1.18. However, if the concentration is being performed on stool preserved in a formalin-based fixative, the specific gravity of the zinc sulfate should be 1.20.
