What's Bioremediation?
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
Bioremediation in Action: A Historical Milestone
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.
It supports both aerobic and anaerobic studies, covering applications from biodegradability testing to large-scale bioremediation.
With intuitive software, expert support, and regulatory-ready data, it helps labs achieve reliable results while streamlining workflows.

Frequently Asked Questions - FAQs
The Micro-Oxymax is an ultra-sensitive respirometer designed for precise measurement of gas exchange (O₂, CO₂, CH₄, etc.) in solid or liquid samples. It's modular and flexible. Use for both aerobic and anaerobic studies in bioremediation and biodegradation (home and industrial compost, landfill, marine water, soil, and wastewater). In addition to other respirometry application fields, such as biomethane potential (BMP), insect respiration, bioleaching, and fermentation.
Most ISO and ASTM standards call for running samples in triplicate (3 blanks + 3 controls + 3× number of samples). Some labs prefer quintuplicates for greater statistical accuracy (5 blanks + 5 controls + 5× number of samples). Our team can help you determine the size of your system based on your throughput requirements.
Available gas channels include CO₂, O₂, CH₄, CO, H₂, H₂S, NO, NO₂, and N₂O.
Yes, the Micro-Oxymax is fully modular. You can add more chambers (up to 80) and additional gas sensors at any time.
The system requires a PC (Windows-based) and calibration gas. We provide the exact gas specifications before installation so you can have everything ready.
The Micro-Oxymax offers CO₂ recovery detection as low as 0.03 mg per hour in closed-loop mode, with minimum gas exchange detection of ~0.2 µL per hour in specific configurations, and supports multiple programmable gas sensor options for flexible research applications.
Yes — there is a gas blending option so you can run your experiments under altered atmospheric conditions.
One of our application engineers will come on-site to install the system, configure the software, and train your team to ensure you are fully prepared to begin testing.
Test for all major aerobic and anaerobic biodegradation standards, including industrial and home compost, landfill, marine water, soil, and wastewater (e.g., ISO 14855, ASTM D5338, ISO 22403, ASTM D6691, EN 13432).
Yes, the Micro-Oxymax-C is a streamlined, open-loop version explicitly designed for compost standards — a cost-effective choice if your work is focused only on compost biodegradation.
Perform a simple calibration before each test. The process takes about ten minutes and ensures maximum accuracy.
While third-party certification is still required, the Micro-Oxymax provides the confidence you need before submitting formulations. By monitoring CO₂ recovery, you can often determine pass or fail trends early in R&D and avoid wasting time on non-promising tests.
Yes, the system comes with software that enables real-time data collection and management. Capabilities include exportable data, graphical views during experiments, etc. You can download any future software updates when they become available.
The programmable enclosure operates from 4 °C to 60 °C, covering everything from refrigerated soil and marine studies to thermophilic compost testing.
Yes. By tracking CO₂ recovery rates, researchers can often predict material degradation outcomes well before the full test duration, enabling faster go/no-go decisions in product development.
