MINIVAP VP Vision is a highly versatile portable vapor pressure tester that features best-in-class precision and a pressure range of 0-2000 kPa. It is the first analyzer that demonstrates excellence in engineering by earning certificates for robustness and durability. Based on Grabner´s cutting-edge Cockpit™ technology, the instrument offers unmatched networking capabilities and enables worldwide access to analyzers.

Engineered for Excellence

MINIVAP VP Vision measures gasoline, jet fuel, crude oil, LPG and solvents. The analyzer provides a wide pressure range of 0 – 2000 kPa, without compromising precision. Long-term testing has demonstrated an unmatched repeatability of less than 0.2 kPa. The newly developed Grabner 2D-Correction™ (273 points) and exact piston positioning guarantee that accurate and precise results are received over the full measuring range.  MINIVAP VP Vision incorporates Grabner´s Sampling Pro™ valve design, which during ruggedness tests proved to be the best-in- class piston based design for minimizing cross contamination between various sample types.

Access. Anywhere. Anytime.

With the Cockpit™ PC software multiple instruments are automatically recognized and devices all around the world can be configured, monitored, diagnosed, serviced and upgraded from one central lab. The software can be accessed through a secure VPN tunnel, allowing for true mobile access to instruments from any place at any time. A unique call home function facilitates easy uplink to our well trained support team.

Highest Accuracy – Lowest Limit: Low Volatility Model MINIVAP VPL Vision

While the standard VP model is designed to sustain pressures up to 20 bar, some applications require increased measurement sensitivity for samples with a very low volatility. These applications include e.g. the measurement of Diesel, Oils or Flavors & Fragrances. The MINIVAP VPL Vision model is designed for low volatility measurements up to 150 kPa (21.8 psi). It shows a measuring repeatability better than 0.1 kPa for low volatile samples.

Direct / Indirect Determination of the Absolute Vapor Pressure (“VOC-Methods”)

The model MINIVAP VPL Vision was developed to automate the manual ASTM D2879 Standard Test Method for Vapor Pressure by Isoteniscope for low volatile samples, which is used by the chemical industry. The instrument incorporates a direct and an extrapolated “VOC” method for absolute vapor pressure measurement of single- and multi-component samples.

The direct “VOC”-method is a static method for determining the absolute vapor pressure required for safety data sheets. The indirect method additionally allows to extrapolate to extremely low pressures or to temperatures that exceed the instruments temperature range (-100°C to +300°C). Both methods yield results comparable to the static ASTM D2879 Isoteniscope method, but do not require sample evacuation prior to testing. Based on the GRABNER Triple Expansion Method, air/gases are removed automatically from the measurement result and the sample composition is maintained during measurements.

“VOC”-methods are available in both the MINIVAP VPL and the VP Vision analyzer. Because of a better sensitivity for low volatile samples, the precision of the VPL Vision is significantly better in the pressure range of 0.1 to 30 kPa.

MINIVAP VPXpert or MINIVAP VPSHcrude_oil_aks3 (only VPSH: plus Rocking Plate) – Floating Piston Cylinder GRABNER INSTRUMENTS’ complete package for the vapor pressure measurement of crude oil according to ASTM D6377 (Expansion Method). MINIVAP VPXpert 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. MINIVAP is the world wide standard instrument that is 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 Grabner 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 increasesrefinery profits: it reduces expensive labor time, eliminates operator bias and has considerably improved test precision that offers the advantage to blend closer to the limits and avoid product give-away. MINIVAP VPS is mostly used for QC purposes while VPXpert and VPSH offer even more features for crude oil and R&D applications, like volatility studies at elevated temperatures and at very low vapor/liquid ratios.
