Founded in Richmond, Canada, Phase Technology®—a flagship brand under PAC Instruments—is a global pioneer in the design and manufacture of high-precision cold-flow property analyzers. For decades, they have set the industry standard for the automated testing of jet fuel, diesel, and lubricants, providing critical insights into fuel behavior at low temperatures. As the authorised Australian partner, we provide local refineries and testing laboratories with direct access to these sophisticated systems, ensuring compliance with rigorous quality standards across the Petrochemical sector.

The engineering core of Phase Technology is defined by its commitment to speed and accuracy, often delivering results for complex parameters in less than 20 minutes. Their patented Diffusive Light Scattering (DLS) technology allows for the detection of the very first appearance of crystals, providing superior sensitivity compared to manual methods. We back this innovative PAC portfolio with our 70 years of local expertise, providing the technical guidance and service infrastructure necessary to keep your fuel quality workflows operational and audit-ready.

Technical Applications for Phase Technology in Australia

In Australian fuel production and aviation logistics, ensuring that products meet strict ASTM and Def Stan specifications is a primary technical driver for safety and performance. The range of Measuring and observing and testing instruments includes the highly popular 70Xi series, such as the Phase Freeze Point Analyzer with Single Shot Automatic Sample Injection. This system eliminates manual pipetting errors and ensures that jet fuel samples are tested with the highest degree of repeatability, even at temperatures below -80°C.

For more complex analytical requirements, the integration of multi-parameter platforms like the JFA-70Xi and DFA-70Xi allows for the simultaneous measurement of freeze, cloud, pour point, viscosity, and density in a single run. These systems are often paired with advanced H2S monitoring solutions, such as the Stanhope Seta H2S Analyser with Vapour Phase Processor, to ensure comprehensive product safety and regulatory compliance. By utilizing genuine Vapour Phase Processor Cartridges and local calibration support, Australian laboratories can maintain peak throughput without compromising on data reliability. For industrial material testing needs outside of fuels, we also offer the Phase-II PHT-1800 Portable Digital Hardness Tester to support broader geomechanical and metallurgical analysis.

Frequently Asked Questions

What is the "Dynamic Duo" concept in Phase Technology laboratories?
The "Dynamic Duo" refers to the pairing of a standalone 70Xi analyzer with an automated 70Xi autosampler system. This allows labs to use the manual unit for urgent, one-off samples while the autosampler handles high-volume batch testing, maximizing overall laboratory efficiency.

How does the single-shot automatic injection improve test accuracy?
Manual pipetting is a common source of measurement variability. The automatic injection system draws the exact volume required by the ASTM method every time, eliminating operator bias and reducing the risk of sample contamination or spilled product.

Do these analyzers require an external water bath or chiller?
No, the 70Xi series is completely self-contained. The integrated Peltier cooling system is powerful enough to reach temperatures as low as -88°C without the noise, maintenance, or space requirements of an external chiller unit.

Can one unit test multiple fuel types like jet fuel and diesel?
Yes, many models are configurable. For example, the JFA-70Xi is a 3-in-1 analyzer for jet fuel (freeze, viscosity, density), but can be upgraded to a 5-in-1 system to include cloud and pour point for diesel samples.

How is the self-cleaning cycle managed between different samples?
The 70Xi series features an automated flush and clean cycle that does not require external solvents. This "green" cleaning process prevents sample carry-over and protects the sensitive measurement cell from damage caused by manual cleaning methods.

What kind of local technical support is available in New Zealand?
Our Auckland-based service centre provides full support for the Phase Technology range across New Zealand. This includes professional installation, preventative maintenance plans, and rapid breakdown repair by factory-trained engineers to ensure minimal downtime for your refinery or testing lab.
