MINIFLASH FP Vision
Industry 4.0-Ready Flash Point Tester
The flash point tester MINIFLASH FP Vision is uniquely designed to determine the flash points of liquids and solids. The analyzer uses Grabner flash point detection method, which is triggered by an energy-controlled electric arc and measures instantaneous pressure increase inside a closed chamber. By heating the test chamber from the top, the analyzer prevents condensation of high volatile compounds and guarantees improved test results.
MINIFLASH FP Vision continuously closed cup design and small sample volume of only 1-2 ml offer maximum safety. No offensive fumes are released in the testing area and little to no sample waste is registered when performing a flash point test. The fast thermoelectric cooling at the end of each flash point test plus the easy handling of the instrument also save expensive labor time.
MINIFLASH FP Vision is part of the Vision analyzer line. Vision analyzers support remote access to test results via the COCKPIT Software and are equipped with a full-color touchscreen. The touchscreen of the MINIFLASH Vision features an easy-to-use graphical interface and do away with the need for training. Any technician is capable of running a flash point test with MINIFLASH FP Vision! As other analyzers of the Vision product line, MINIFLASH FP Vision offers hassle-free communication with USB, Ethernet, LIMS and PCs and nearly unlimited storage capacity for test results.
Grabner Instruments offers two versions of MINIFLASH FP Vision: MINIFLASH FPH Vision, for high temperatures up to 400°C, and MINIFLASH FP Vision, for temperatures between -25°C and 120°C.
The flash point testers determine flash point according to ASTM D6450 and according to 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. The official statement from the ASTM committee goes as follows: "there is no statistically significant bias observed between ASTM D7094 and ASTM D93 Procedure A”. Also, ASTM D7094 has been approved by the ASTM committee for the Diesel Fuel and Kerosene specifications ASTM D975, D396, D2880 and D3699.
Test results delivered by these ASTM methodsare equivalent to other well known standards such as Abel and TAG. Additionally, thanks to the unique design of Grabner flash point analyzers, MINIFLASH FP Vision can be used for difficult applications like flash point testing of biodiesel and of contaminated samples. Examples of contaminated samples that can be tested with the analyzer are: diesel fuel in lube oil and gasoline in diesel fuel. The MINIFLASH FP Vision analyzer includes improved methods for simulation of EN ISO 3679 and EN ISO 3680 too.
Due to true portability and rugged housing, the MINIFLASH FP Vision is the perfect solution for mobile labs and military applications.
The New 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 above 400°C and optimizes Peltier performance and life time.
Ignition Protection Technology is intrinsic to the MINIFLASH design. Tests require only 1-2 ml samples. Plus, there is no open flame during the flash point testing. 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!
Sometimes samples contain small concentrations of flammable compounds, which do not show a definite flashpoint. MINIFLASH FP Vision detects even a very small flame and graphically shows the presence of contaminations in those samples.
The ability to control parameters like heat rate, ignition energy and the amount of atmospheric oxygen present in the combustion chamber let users simulate nearly any flash point method and environmental condition.
Wide Range of Applications
With Grabner flash point testers, flash points are determined over a wide temperature range, simulating all standard closed cup methods as well as GO/NOGO tests using only 1-2 ml samples. The programmable fuel dilution curve (diesel fuel or natural gas in lubricating oil) is a powerful tool for used oil analysis to prevent costly engine troubles. Over the last years, the outstanding performance of MINIFLASH has proven effective for transport regulations/classifications, product specifications and used oil analysis all over the world.
Other Applications for MINIFLASH include:
Flash point testing of residuals.
Fast screening of jet fuel and diesel fuel to check for the presence of contaminants with flash contaminants.
Advantage: high temperature range and very safe operating procedure.
Flash point testing of products containing solvents like ethanol, IPA, glycerol, etc.
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 significantly reduces costs for 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 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.
Maintenance of Engines and Pumps:
Fuel dilution in lube oils changes oil viscosity and hence its lubricating properties. The result is increased friction and wear of mechanical parts that can eventually lead to serious damage and engine drop-out. Fuel dilution decreases the flash point.
Advantage: preventive maintenance.
Down to -25°C (-13°F) with water cooling
An aluminum cup (1) with a capacity of 7 ml and containing 2 mL of sample is resting in the sample cup holder. For the test, the sample cup is lifted to the temperature controlled oven (2), forming the test-chamber with a metal to metal seal. A thermocouple (3) is immersed into the sample to measure the temperature. The temperature of the oven is controlled by Peltier elements (4) and an air cooled heat sink (5). The vapor is ignited by a high voltage arc (6) inside the test-chamber. At the flash point, the pressure inside the sealed measuring chamber is increased significantly, which is detected by a built-in pressure transducer (7). A rotating magnet and a small magnet (8) inside the the sample cup provide stirring.
Continuous product development may make it necessary to change product specifications
