General information

Density determination

Sodium polytungstate (SPT) is perfect for preparation of heavy liquids. Carl ROTH offers an environmentally friendly alternative to using zinc chloride and mercury saline solutions or highly toxic halogenated hydrocarbons to conduct the sink or swim analyses required for density determination.

Properties:

  • Highly water soluble
  • pH-neutral solution adjustable
  • Maximum achievable density of the solution is 3.1 g/cm³ at 25 °C
Advantages:
  • Non-toxic
  • Non-flammable
  • Odourless
  • Low viscosity
  • Easy to use
  • Extremely easy cleaning of the sinking and floating material with water
  • Environmentally friendly
