We producing Heavy liquid HPS-W on the basis of Heteropolyoxotungstates(density of 2.85-3.00 g / ml). HPS-W is a heavy low-viscosity(about ~10 cP) concentrated aqueous solution of sodium heteropolyoxotungstate light-yellow color maximum density of 3.05 g / ml at the normal conditions.
Heavy liquid HPS-W is not volatile, non-toxic, fire, explosion, radiation and environmental safety; It has no restrictions for the transport of any kind of transport; It is designed as a replacement for toxic tribromomethane (bromoform) and put into production in 2012.
Scope of application heavy liquid: in the mineralogical analysis - the separation of minerals by density, density determination mineral, identification of gemstones; heavy media in the process of gravity concentration ores and golden or diamonds concentrates; the separation of the mineral from organic residues (bones, pollen, wood) for the processing of rocks and soils; separation of rare metals (mercury, precious metals) from the glass, ceramic and plastic for utilization of medical devices and radio-electronic components; as a weighting agent in drilling acidic solutions processing of oil wells; reagent for the precipitation of proteins, alkaloids, purines.
Heavy liquid HPS-W can replace toxic bromoform, tetrabromoethane, solution tetraiodokadmate of barium Ba [CdI4] in all the above processes. It can be easily regenerated, the operation does not require the use of organic solvents.
Heavy liquid HPS-W can replace LST & SPT very effectively.

Heteropolyoxotungstates (Polyoxometalates) exhibits antiviral and bactericidal activity (however, clinical trials are required).
