Sodium Polytungstate (SPT)

SPT Heavy Liquid is a low-toxicity, fully recyclable substitute for brominated organic solvents with a low viscosity and excellent thermal stability. SPT is a highly transparent, yellowish-green solution, available in densities of up to 3.0 g/cm³ and can be configured as a pH-neutral solution.
