eraflash lt

The low-temperature flash point tester.

Another member among eralytics’ flash point testers is the eraflash lt. It is based on the unrivalled performance of eraflash and adds new benefits for fast low-temperature flash point testing. The stacked Peltier design allows measurements in full compliance with ASTM D7094, ISO 24966 and IP620 with oven temperatures as low as -40 °C. The cooling rates are much faster than in any other instrument on the market.

Low temperature flash point testing

To increase sample throughput for low-temperature flash point testing, eraflash lt is equipped with stacked Peltier elements. This provides three major improvements for low-temperature testing:

  • Faster turnaround: Cooling speed is increased by approximately 35%.
  • Expanded stand-alone range: Without external cooling, temperatures approximately 35 °C below ambient (e.g., -15 °C) are easily accessible.
  • Maximum low-temperature capability: With external water cooling, low-temperature flash point testing down to an oven temperature of -40 °C is possible.

Simple, low-temperature flash point testing is now achievable without the need to cool the entire instrument or environment prior to measurement.

Further improvements for low temperature flash point testing

eraflash lt is equipped with a coolant valve that automatically shuts off coolant flow when not needed. This helps eliminate humidity condensation on the cooler. During cool-down, ice formation on the oven surface is prevented by using a cooling cup that shields the oven from ambient air. eraflash lt also allows samples to be pre-cooled prior to the actual measurement.

Applications

eraflash lt is the ideal partner when measuring samples with flash points below ambient temperature or even below 0 °C. According to ASTM D7094 and IP 620, flash point measurement must start 18 °C below the expected flash point. For a sample like ethanol with an expected flash point of around 12 °C, the measurement must start at -6 °C. eraflash lt speeds up the analysis because it is optimized for low-temperature flash point measurements. Flash points of crude oils, especially those containing highly volatile compounds, can fall well below 0 °C. Industries with high sample throughputs, such as the fragrance industry, also benefit from fast turnaround times due to the instrument’s enhanced cooling rate.

Measurement procedure

Just four easy steps are required for safe, low-temperature flash point testing at maximum precision:

  • Enter the sample ID and operator name
  • Select the measurement standard and add additional parameters (e.g., expected flash point)
  • Fill the sample cup with sample (1 mL or 2 mL), place the sample cup inside the measurement chamber, and close the door
  • Press the RUN button

The instrument now visualizes the measurement procedure on the screen, showing the sample and oven temperatures, as well as a pressure gauge displaying the pressure increase after ignition. After the measurement, the flash point temperature is automatically corrected for atmospheric pressure and rounded to the nearest 0.5 °C. The result is saved in the corresponding result file. To improve the measurement further, a cooling cup can be used to prevent ice formation during the cool-down process.

Specific characteristics of the low-temperature flash point test can be observed using Combustion Graphics™, making eraflash lt the ideal solution for both R&D and quality control.
