- Model 10-position Autosampler - The Automated Side of Safe Flash Point Testing



The latest addition to eralytics’ flash point tester series combines safest measurement with a 10-position autosampler. The intrinsically safe CCCFP methods ASTM D7094 and ASTM D6450 are ideal for unattended measurements. ERAFLASH S10 ignites the vapors of 1-2 ml of sample inside a closed chamber and measures the according pressure increase.

Autosampler for Flash Point Testing

ERAFLASH S10 is the first 10-position autosampler for flash point testing. It uses the intrinsically safe methods ASTM D7094 and ASTM D6450. With a low sample volume of 1-2 ml only and the continuously closed sample cups they are ideally suited to built a completely safe autosampler for flash point testing.

This makes ERAFLASH S10 the ideal solution for unattended flash point testing.

Cost Efficient Fast Flash Point Testing

When looking at valuable products, especially with small batch sizes, flash point testing using the well-known Pensky Martens principle can consume a significant amount of sample, thus leading to high analytical costs. When performing flash point testing according to ASTM D7094  just 2 ml of the sample are needed. ASTM D6450 reduces this volume even further to 1 ml.

ERAFLASH S10 is therefore a welcome addition to testing labs handling large amounts of costly samples every day. This includes fragrances, paints and varnishes producers.

Peltier Boost Technology™

Similar to eralytics’ single position flash point tester the patented PBT – Peltier Boost Technology™ allows flash point testing below 0°C (32°F) and above 200°C (392°F) with a single instrument. PBT separates the Peltier elements during the heat up at 100°C shielding them from higher temperatures that would normally harm them. During cool down, however, they can be used for active cooling starting at 200°C and thus reduce the turnaround time significantly. PBT also facilitates the same temperature range of -25°C (-13°F) to 420°C (788°F) of our single position flash point tester in an autosampler for flash point testing.

Optional Cooling Lid

Another great benefit is the optional cooling lid for the ERAFLASH S10 ten-position autosampler – which is a unique solution for many reasons: The pre-cooled lid allows easy and time-saving sample preparation. As a consequence the sample cups are pre-cooled as well what means that no complicate cooling prior sample filling is necessary.
The pre-cooled samples need less intensive cooling during sample measuring resulting in shorter turn-around times. As no elevated temperatures are reached and volatile compounds are far less likely to evaporate before measurement is started, more precise and reliable results are reached.

Measurement Procedure

Just four easy steps are required for an unattended safe and fast flash point testing at maximum precision:

  • Enter sample IDs and operator name
  • Select the measurement standards and add additional parameters (e.g. expected flash point)
  • Fill up to 10 sample cups with samples, place the sample cups on the carousel and close the cover plate
  • Press the RUN button

During flash point testing the instrument visualizes the measurement procedure on the screen showing the sample and oven temperature as well as pressure gauge displaying the pressure increase after ignition.Additional information about the currently measured sample, as well as finished and still samples to be measured are displayed. After the measurements the flash point temperature is corrected for the atmospheric pressure and rounded to the next 0.5°C. All results will be saved in the corresponding result file.
