    AFAIK, 'isotonic' simply means the solution has about 300 mOsm of solute. I don't know if it additionally requires (for example) 140 mM Na, 5 mM K, 100 mM Cl, etc. etc. What is your application?

    No. "isotonic solution" has different meanings/composition depending on history, location and use. Sorry, I'm not more specific, but the primary research literature should have details (and comparison of various national bodies standards will also show differences). (more modern standards will tend to be more global, of course).
