Our SA-1 small animal respirometry system differs from our SA-2 system by using flow generators optimized for lower flow rates, and thus improved ease of use with smaller animals. It produces accurate, reproducible data from animals from large arthropods up through mice in size. It can be used in push, pull mode or stop-flow mode. In stop flow mode the systems' measurement range can easily be extended to small insects. It is available with an optional water vapor pressure analyzer for flow and dilution compensation without requiring scrubber chemicals. 

The SA-1 small animal respirometry system is normally supplied with both oxygen and carbon dioxide analyzers, and measures oxygen consumption rate, CO2 production rate, RQ, and water loss rate. 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 is fully automated. Optionally, multiple animals can be measured in sequence. 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.
