ERAFLASH S10™ – New Cooling Lid Extends its Applicability

Nov 30 2017 Comments 0

By definition, the flash point of a substance is the temperature, at which the vapours of it can be ignited by an external ignition source. The more volatile a substance is the lower its flash point will be. The lower the flash point is the more dangerous a certain chemical is. This influences the way how the chemical must be transported and declared.

More volatile substances tend to evaporate faster that less volatile substances which specifically tends to be a problem for substance mixtures. If such samples are stored incorrectly the volatile parts will escape and the flash point will increase. If, due to such circumstances, the declared flash point is too high this will lead to substantial financial penalties as soon as it is uncovered by transportation authorities.

Samples that flash around ambient temperature or below are especially prone to such errors in sample handling and measurement. Such samples also pose special challenges for instruments with auto samplers such as the ERAFLASH S10. Covering the samples with a lid already reduces the evaporation effect dramatically.

Obviously, cooling this lid will further slowdown the evaporation process ensuring unaltered samples from charging the auto sampler to the actual measurement. ERAFLASH S10 can now be equipped with such a water-cooled lid that keeps the sample cups cold prior to the measurement. Internal tests have proven that this cooling lid allows to accurately measure samples (flash point around 4°C due to contamination with a highly volatile substance) after being stored on the auto sampler’s carousel for 1.5 hours.

In combination with its unrivaled temperature range of -25 to 420 °C (-13 to 788 °F) ERAFLASH S10 cannot only be used for fuel specification purposes. It is also an extremely cost-efficient tool from the flavours and fragrances industry all the way to big used oil testing facilities. All industries profit from the small sample volume of only 2ml and the patented Peltier Boost Technology (PBT)TM allowing for unmatched heating and cooling rates. This gives you the shortest turnaround times on the market.
