Designed for the everyday user

Fully automated.
Pressurized by design.

This device is designed for the everyday user and is fully automated, with minimal operator interactivity.

A small footprint, navigable interface, rugged aluminum casing, and simple operations make the ERAVAP a desirable unit for both laboratory and on-the-go vapor pressure testing. Quick connect inlets paired with a pressurized cylinder ensure LPGs maintain a pressurized environment, retaining the sample from escaping due to its high volatility.

LPG applications + Compliance

System pressure.
Safety by design.

This device is fully compliant with ASTM D6897, making it the ideal unit for R&D, QC, and many more applications using a single analyzer. It also covers ASTM D5188, D5191, D6377, D6378, and EN 13016, so gasoline and crude oil methods run on the same instrument.

Key measuring parameters

   Vaporization Tendency

   V/L ratio gives insight into the tendency of fuel to vaporize in an engine.

Next generation silicon detector technology

Improved peak resolution.
Superior precision.

A detector upgrade built for the measurements that punish ordinary EDXRF.

Employing the next generation silicon detector technology, the enhanced NEX QC+ affords significant improvement in elemental peak resolution and counting statistics, resulting in superior calibrations and measurement precision for the most challenging measurements.

Sample handling

One chamber.
Many sample types.

A large 190 × 165 × 60 mm sample chamber accepts single-position 32 mm and 40 mm apertures, a bulk sample aperture, and optional automatic sample changers, with analysis in air or helium. The icon-driven software handles qualitative and quantitative analysis, normalization and validation, fundamental parameters, and LIMS-compatible data export, with a flow-bar wizard for building new applications.
