    Grabner/Reid Vapor Pressure On-Line Analyzer

    START workshop video

    MINIVAP ON-LINE is a process monitoring analyzer for the determination of the vapor pressure of gasoline, crude oil, LPG and NPG. Also, the vapor-liquid ratio (LVR) of gasoline can be measured. The measuring principle is identical to the worldwide used laboratory instruments MINIVAP and therefore the MINIVAP ON-LINE produces equivalent results.

    Up to 2 different sample streams can be connected to one single analyzer. It is the only available process vapor pressure tester that fully complies to the industry relevant ASTM standards for gasoline (ASTM D6378), crude oil (D6377) and LPG (D6897).

    The unmatched accuracy makes refineries save thousands of Dollars each day!

    The measuring principle is based on the triple expansion method of Grabner Instruments´ worldwide approved and accepted laboratory vapor pressure tester for gasoline and crude oil: MINIVAP VPS. The US-EPA declared MINIVAP the official reference instrument for the USA in 1993.

    With MINIVAP ON-LINE, the vapor pressure of gasoline (D6378 / D5191), crude oil (D6377 / D323), liquid petroleum gas (D6897 / D1267) and the vapor-liquid ratio temperature of gasoline (D5188) can be determined. With possible connection of up to 2 different sample streams, these measurements can be performed with one single instrument.

    MINIFLASH FLP / H / L Flash Point Tester

    Product | Small | MINIFLASH FLP
    MINIFLASH - The Safety Standard in Flashpoint Testing

    MINIFLASH is a uniquely designed flash point series of instruments for the automatic determination of the  flash point of liquids and solid samples according to ASTM D6450 and the advanced ASTM D7094 standard. This procedure describes the “Standard Test Method for Flash Point by Modified Continuously Closed Cup (MCCCFP)”, which offers the highest repeatability and reproducibility and an excellent correlation to the D93 Pensky-Martens method: "There is no statistically significant bias observed between ASTM D7094 and ASTM D93 Procedure A” as concluded during the last Round Robin. ASTM D7094 has been approved by the ASTM committee for the Diesel Fuel and Kerosene specifications ASTM D975, D396, D2880 and D3699.

    Furthermore, test results are equivalent to other well known standards such as Abel and TAG, and thanks to its unique design, MINIFLASH can be used for more difficult applications such as flash-point testing of contaminated samples like diesel fuel in lube oil or
    gasoline in diesel fuel and for biodiesel testing.

    Its continuously closed cup design and small sample volume of only 1-2 mL offers maximum safety, avoids offensive fumes in the testing area and reduces sample waste. The fast thermoelectric cooling at the end of a test and the
    fast and easy handling of the instrument, save expensive labor time.

    Due to the true portability and rugged housing, the MINIFLASH is also the perfect solution for mobile labs and military applications.

    The New Technology

    Product | Small | MINIFLASH Arc
    The MINIFLASH series of instruments is using the Grabner flash detection method of measuring the instantaneous pressure increase inside the continuously closed chamber due to a high energy electric arc. The fast thermoelectric cooling after each test prepares the instrument for the next test in a very short time. Heating the test chamber from the top avoids condensation of high volatile compounds, significantly improving the test results.

    Products | Flashpoint | Peltier Protection Technology
    Peltier Protection Technology™
    For a quick sample turnaround and extended instrument life time Grabner Instruments developed fast thermoelectric regulation of heating and cooling. This technology permits to extend the measuring temperature to well above 400°C and optimizes Peltier performance and life time.

    Products | Flashpoint | Ignition Protection TechnologyIgnition Protection Technology™
    Ignition Protection Technology™ is intrinsic to the MINIFLASH design. Only 1-2 mL of sample are required for testing the flash point - without an open flame! The continuously closed cup design, automatic explosion probing and a controlled air feed protect against fire and offensive fumes - for unmatched safety in flashpoint testing!

    Wide Range of Applications
    The flashpoint is determined over a wide temperature range, simulating all standard closed cup methods as well as GO/NOGO tests. Over the last years, the outstanding performance of MINIFLASH has proven effective for transport regulations/classifications, product specifications and used oil analysis (programmable fuel dilution curve to prevent costly engine troubles) in laboratories all over the world.

    Flash Point of FAME (Biodiesel) and ASTM method D6751-03
    Blending of Biodiesel (B100) with Diesel Fuels has become increasingly important in order to reduce the amount of carbon dioxide emission in the atmosphere. In the chemical reaction process to produce biodiesel, a short chain alcohol is used to dissolve the catalyst and to assist in the conversion of oil or fat into a fatty acid methyl ester (biodiesel). The excess alcohol is afterwards removed and measuring the flash point of each phase, with the MINIFLASH fully automatic flash point tester, provides a fast indication of the presence of any remaining flammable alcohol.

    Other Applications for MINIFLASH include

    Flash point testing of Residuals, Sludge, Bitumen, Tar, Asphalt...
    Fast screening of Jet Fuel, Diesel Fuel to check for eventual presence of low flash contaminants.
    Advantage: high temperature range and very safe operating procedure

    Flash point testing of products containing solvents like ethanol, IPA, glycerol...
    Advantage: small sample volume

    Flash point testing of flammable goods to check for compliance with transport safety regulations.
    Advantage: easy handling

    Flavors and Fragrances
    Flash point testing of aroma products containing alcohol based solvents.
    Advantage: small sample volume reduces testing costs significantly in case of expensive base products

    Paints and Varnishes
    Flash point testing of solvent based paints, varnishes and enamels to determine the safest way of storage.
    Advantage: small sample volume and easy to clean

    Waste Disposal
    Testing of industrial waste like solids (filter slurry...) and unknown mixtures of liquid hydrocarbons.
    Advantage: small sample volume, fast thermoelectric cooling in case of samples having a flash point well below ambient temperature.

    Fuel Protection for Ships, Railway and Heavy Duty Machinery (Mining, Construction), ...
    Fuel dilution in lube oils changes its viscosity and hence the lubricating properties of the oil, resulting in increased wear of mechanical parts due to higher friction which can eventually lead to serious damage and engine drop-out. Fuel dilution decreases the flash point.

    Approved by NAVY, NATO, etc.
