MICRO-OXYMAX
FOR BIOREMEDIATION

Micro-Oxymax Respirometer empowers scientists with precise, reliable data to advance environmental cleanup.

What's Bioremediation?
Bioremediation uses beneficial microbes—bacteria, fungi, and even plants—to break down pollutants in soil, water, and air. These organisms naturally “eat up” contaminants, turning them into harmless substances. Thanks to advances in microbial genetics and bioengineering, this eco-friendly process is becoming more powerful than ever.
Bioremediation vs. Oil Spills
Oil spills threaten ecosystems, marine life, and human health. Traditional cleanup methods, like booms and dispersants, can be effective but often cause further damage. Bioremediation offers a safer solution: microbes break down oil into harmless byproducts like carbon dioxide and water. Sometimes they’re introduced directly; other times, existing microbes are boosted with nutrients to accelerate cleanup—even in major disasters.
Bioremediation in Action: A Historical Milestone
In 1989, after the Exxon Valdez spill, the EPA turned to Columbus Instruments to improve microbial respiration measurement. This led to the creation of the Micro-Oxymax Respirometer, patented for its Closed-Loop method. Since then, it has supported research and cleanup efforts in landmark cases like Deepwater Horizon (2010), cementing its role in advancing bioremediation science.
Why Choose the Micro-Oxymax Respirometer?
Trusted by scientists and environmental professionals worldwide, the Micro-Oxymax delivers unmatched sensitivity and modular flexibility. It supports both aerobic and anaerobic studies, covering applications from biodegradability testing to large-scale bioremediation.
