MINIVAP VPS / VPSH Vapor Pressure Tester The Worldwide Standard Vapor Pressure Tester
MINIVAP VPS and VPSH are extremely versatile instruments for the automatic determination of the vapor pressure behavior of gasoline and gasoline oxygenated blends, live and dead crude oil, solvents and other chemical compounds. Both types VPS and VPSH are the world wide standard instruments that are used by all major refineries, oil and pipeline companies, independent laboratories and car manufacturers.
The US-EPA declared MINIVAP as the official reference instrument for the USA.
MINIVAP VPS/H are stand-alone units that do not require any accessories. The unique piston based design for automatic sample introduction and volume expansion of the measuring cell makes an expensive and bulky vacuum pump unnecessary. The patented measuring principle in combination with the latest standards ASTM D6377 (for Crude Oil) and ASTM D6378 (for Gasoline) avoids tedious sample chilling and air saturation.
This new technology significantly increases refinery profits: it reduces expensive labor time, eliminates operator bias and has a considerably improved test precision that offers the advantage to blend closer to the limits and hence avoid product give-away.
MINIVAP VPS is mostly used for QC purposes while VPSH offers even more features for crude oil and R&D applications, like volatility studies at elevated temperatures and at very low vapor/liquid ratios.
