Cheap liquid with Sp.Gravity betn. 2.8 to 6.5

  1. Oct 15, 2011 #1
    i am trying to find a liquid that is -

    cheaply and easily available;
    easy and safe to use - non-toxic, non-acidic;
    usable at room temperatures;
    with a viscosity less than 10 cp;
    and specific gravity anywhere between 2.8 to 6.5...

    please help?

    thanks a bunch
    warm regards

    Sodium polytungstate solutions have a density of up to 3.10 at relatively low viscosity and non-toxic. Not exactly cheap, but probably the only liquid which is non-toxic in that density range:
