Our IA-2 insect and arthropod respirometry system is an economical but nevertheless fully research-grade respirometry system for use with small animals, typically scanning 3, 7 or 15 animals sequentially. Optimized for stop-flow mode, it can measure animals from large arthropods or small lizards down to individual ants.

The IA-2 insect and arthropod respirometry system can be also used in push or pull mode for larger animals, such as mammals up to mice in size, with minor modifications. Like all of our respirometry systems, it's versatile, re-configurable and expandable. 

The IA-2 insect and arthropod respirometry system is normally supplied with both oxygen and carbon dioxide analyzers, and measures oxygen consumption rate, CO2 production rate, and RQ. Using RQ, the respiratory substrate of the test animal can be determined, allowing accurate translation of gas exchange measurements to energy equivalents, e.g. Watts, Joules/hr or calories/day.

Data acquisition is fully automatic, using our acclaimed ExpeData™ software, the product of over twenty years' experience in computerized data acquisition and analysis. Complete user control over every aspect of the system's operation is supported. Baselining and the switching of gas streams to multiple chambers are fully automated. The analysis of acquired data is uniquely flexible and can also be fully automated, if desired. The respirometry equations used in the system are state-of-the-art.

All necessary tubing and accessories are supplied with the system. Lifetime technical support by published experts in respirometry is included.
