Our SI-3 small insect/Drosophila scanning respirometry system is an economical but nevertheless fully research-grade respirometry system that is capable of resolving small animals down to Drosophila in size, typically scanning 3, 7 or 15 animals sequentially. Optimized for stop-flow mode, it can measure animals over a wide size range, and can be easily and economically re-configured to measure small mammals in flow-through mode.

The SI-3 small insect/Drosophila scanning 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.
