World Class Flashpoint Testing At Your Finger Tips
MINIFLASH TOUCH is a uniquely designed flash point tester for the determination of flashpoints of liquids and solids, using the Grabner flash point detection method of measuring the instantaneous pressure increase inside the continuously closed chamber, triggered by an energy-controlled electric arc. Heating the test chamber from the top avoids condensation of high volatile compounds, significantly improving the test results.
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.
The full color touch-screen of the MINIFLASH TOUCH runs on Microsoft® Windows® software and features an intuitive menu navigation that requires no training for flashpoint testing. Along with its convenient touch screen design, the MINIFLASH TOUCH offers an extended temperature range from 0 to 400°C, hassle-free communication with USB, Ethernet, LIMS and PCs and nearly unlimited storage capacity for programs and results.
MINIFLASH determines the fladh 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: "there is no statistically significant bias observed between ASTM D7094 and ASTM D93 Procedure A” as concluded during the last Round Robin.
 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. The new MINIFLASH TOUCH analyzer also includes improved methods for simulation of EN ISO 3679 and EN ISO 3680.
Due to true portability and rugged housing, the MINIFLASH TOUCH is also the perfect solution for mobile labs and military applications.
The New 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.
 Ignition 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!
 Combustion Analysis™
Sometimes samples contain small concentrations of flammable compounds, which do not show a definite flashpoint. MINIFLASH TOUCH detects even very small flames and graphically visualizes the presence of contaminations in those samples.
Flexibility
The ability to control parameters like heat rate, ignition energy and the amount of atmospheric oxygen present in the combustion chamber allows to simulate nearly any flash point method and environmental condition.
Wide Range of Applications
Flashpoints are determined over a wide temperature range, simulating all standard closed cup methods as well as GO/NOGO tests on only 1-2 mL of sample. 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:
 Petrochemistry:
Flash point testing of Residuals, Sludge, Bitumen...
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
Pharmacy:
Flash point testing of products containing solvents like ethanol, IPA, glycerol...
Advantage: small sample volume
Transport:
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.
Maintenance of Engines, Pumps...:
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.

Principle
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 without notice. |
