The RapidOxy 100 Fuel represents a fundamental change in oxidation stability testing for gasoline and diesel fuels. With the inclusion of ASTM D7525 in ASTM D4814, laboratories can now replace the legacy ASTM D525 method and reduce oxidation stability testing from 240 minutes to as little as 31 minutes, while remaining fully specification compliant. 

Designed for modern fuels where traditional methods struggle to detect reliable breakpoints, RapidOxy 100 Fuel delivers fast, fully automated oxidation stability results for gasoline and diesel fuels from B0 to B100. The result is faster product release, improved laboratory safety, and streamlined workflows that align with today’s regulatory and operational demands.

Why RapidOxy?

Speed

  • Oxidation stability results in a minimum of 31 minutes using ASTM D7525
  • Replace the 240‑minute ASTM D525 workflow
  • Remove bottlenecks in fuel release and increase daily throughput
  • Typical total time under one hour including setup, testing, and cleaning

Simplicity

  • Guided operation with intuitive onscreen prompts
  • Built-in test methods for D7525 and D7545
  • Fully automated pressurization, heating, and measurement
  • All measurement data saved automatically in instrument memory
  • Simple wipe‑clean chamber with no chemical waste

Safety

  • Only 5 mL of sample required compared to 50 mL in legacy methods
  • Fully automated testing sequence minimizes operator interaction
  • Magnetically locked safety hood prevents access to hot or pressurized samples
  • Automatic pressure and temperature shut‑off protects operators and equipment

Space Saving

  • Compact benchtop footprint compared to large D525 heating baths
