Productdetails
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.
- Highly water soluble
- pH-neutral solution
- Maximum achievable density of the solution is 3,1 g/cm³ at 25 °C
- Non-toxic
- Non-flammable
- Odourless
- Low viscosity
- Easy to use
- Extremely easy to clean the sinks and floats with water
- Environmentally friendly
