Is LST Heavy Liquid less sticky to use than sodium polytungstate?
Yes, quite significantly. As a ‘rule of thumb’, SPT is twice as viscous as LST heavy liquid at the same density. At the lower densities such as SG 2.0 there is not a large difference, since both viscosities are low, at around 3 cP. At high densities such as 2.9 g/mL, SPT is more than twice as viscous as LST heavy liquid. Because of LST’s lower viscosity, density separations are faster and more complete, and grains are more easily washed clean. If you accidentally dry out an LST solution, you will be pleased to know that LST solids also dissolve faster in water than SPT solids.
