ERAVAP is a compact, highly precise, yet easy to use vapor pressure tester. A small footprint and the true portability even with an attached 10-position autosampler make it the ideal choice for stationary and mobile laboratories.

New: TVS – Temperature Verification Sensor for ASTM D5191 testing

Eralytics latest innovation (patent pending) for ERAVAP is the TVS™ – ASTM D5191 Temperature Verification Sensor for high precision vapor pressure testing of gasoline. This all-new temperature sensor allows easiest monitoring of the temperature directly in the sample container, featuring an immediate check of the sample preparation even before the actual measurement starts. TVS™ enables the specification of upper (and lower) temperature limits triggering an automatic warning, if the sample temperature does not match the requirements. Thus TVS™ is a very efficient tool helping you to save time and money while improving the quality control in your testing lab.

Superior Repeatability

Recent improvements in the design of ERAVAP led to an improved repeatability and reproducibility for vapor pressure testing. With a repeatability of only r ≤ 0.15 kPa and a reproducibility of R ≤ 0.50 kPa for ASTM D5191 and D6378 reference materials at 37.8 °C (100 °F) it clearly outperforms the precision statements of its own ASTM standards. Using ASTM D6378 instead of D5191 for vapor pressure testing additionally eliminates any operator bias caused by incorrect sample preparation needed only for ASTM D5191.

Please reference the graph for latest repeatability measurements of the latest ERAVAP generation using cyclopentane and pentane at 37.8°C (100 °F).

Outstanding Design

With its quality-centric design ERAVAP was not only designed for highest precision but also for highest durability. The self-lubricating piston and the powerful Peltier elements are the instrument’s centerpiece. It is built for highest sample throughput rates at minimum maintenance. Furthermore, recalibration of the instrument can be performed without any special tools or disassembling the unit. Eralytics patent pending Pure SamplingTM technology minimizes the possiblity of cross contamination between measurements.
