Product Quality Control and Research

The Searle Biodiesel Program includes an extensive chemical analytics lab that allows our students to test all of our fuel to ensure it meets the highest quality standards. We use industry standard equipment, peer reviewed procedures, and cross check our results with an external (third party) lab for accuracy. This equipment also allows us to perform research, test our BioSoap, and offer some testing services to other schools making biodiesel.

We perform a suite of critical tests on every batch of biodiesel before it goes to our customers, including:

Free Glycerin High levels indicate incomplete purification
Total Glycerin High levels indicate an incomplete chemical reaction
Water Content High levels indicate incomplete fuel drying or improper storage
Oxidation Stability Low results point to a reduced shelf life
Cloud Point Results guide safe biodiesel use in cold temperatures
Cold Soak Filtration High results indicate poor cold weather performance
Visual inspection Excellent indicator of approximate water content or contamination

We also perform additional tests as part of our quality control and research protocols:

  • Test
  • Density
  • Kinematic Viscosity
  • Methanol Content
  • Acid Number
  • Flash Point
  • Sulfur Content
  • Sulfated Ash Content
