About Us

Innovators in Fuel Maintenance

Conidia Bioscience research, design, develop, manufacture and globally distribute innovative solutions for maintenance of fuel systems.

Our products are designed to offer practical and easy to use, industry leading solutions to both maintain and monitor the stored fuel in your system, whether that be a fixed ground installed diesel fuel tank, or in an aircraft wing. Through simple steps of ensuring water doesn’t develop within stored fuel, and instant testing at the tank, we keep fuel contamination free and ready to use, avoiding costly remedial action and fuel system failures.


Aviation, marine and land diesel sector fuel tests

Conidia Bioscience celebrates more than 20 years of supporting the development, manufacture and supply of fuel tests into aviation, marine and land diesel sectors.

Our suite of tests detects microbiological contamination at the tank for middle distillate fuels using a fast, easy to use immunoassay antibody technology that gives results in minutes and comes with a digital platform, FUELSTAT® Result to record the results in the field digitally.

These tests, invented by Dr Joan Kelley, were initially developed as part of the international intergovernmental research and publishing organisation CABI. In 2000 Conidia Bioscience was formed and we are now supplying well over 100,000 test kits each year across the globe.
