Globally well-known Performance
ERAVAP is a compact, highly precise, yet easy to use vapor pressure tester. A small footprint, true portability even with an attached 10 port autosampler and its rugged aluminum casing make it the ideal choice for stationary and mobile laboratories.
Not only does the California Air Resource Board (CARB) rely on the unrivaled precision of ERAVAP but recently the U.S. EPA also decided to use ERAVAP as their reference instrument for vapor pressure testing. The very same instrument is field deployed by the US military in mobile laboratories around the world.
Superior repeatablility
Recent improvments in the design of ERAVAP led to an improved repeatablility and reproducibility for vapor pressure testing. With a repeatability of only r ≤ 0.15 kPa and 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 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
Range of Applications
The area of applications ranges from freely programmable test methods for R&D labs to push-button simplicity. With its extended temperature range from -20 °C to 120 °C (4 °F to 248 °F) and V/L ratios ranging from 0.02/1 to 100/1 it can cope with the most difficult measurement scenarios as well as with routine analysis. Vapor pressure testing of up to 1000 kPa is possible. In combination with a 12 V DC adapter it can be even run by a vehicle battery, allowing vapor pressure testing in the field.
With its innovative design ERAVAP is capable of measuring gasoline, oxygenated gasoline as well as any other solvent or even polymers. It is used worldwide by refineries, terminals, oil and pipeline companies as well as authorities and independent laboratorie
High Viscosity Module
ERAVAP already covers a wide range of applications with its standard configuration. However, if the viscosity of the samples increases it gets more difficult to draw them into the measurement cell. In such cases heating up the sample prior to introduction helps. During the measurement the sample sitting in the tubes will cool down potentially blocking them after the measurement.
ERAVAP’s new high viscosity extension heats the inlet and outlet as well as all transfer tubes up to 70°C. The temperature is regulated to a defined value set in the measurement menu of the instrument. Using this new module even further extends the applicability of ERAVAP to a new range of samples.

Measurement Procedure
Beside sample preparation according to the relevant standards, just four easy steps are needed for high quality vapor pressure testing:
Enter sample ID and operator name
Select the measurement standard and add additional parameters when necessary
Place the sample beside the analyzer and put the tubing inside the sample
Press the RUN button
The instrument now visualizes the measurement procedure on the screen showing the sample and piston position, as well as the temperature and pressure within the measurement cell. The resulting vapor pressure is calculated according to the relevant standards and displayed.
