Our LA-2 system produces accurate, reproducible data from animals from large rats up to resting humans in size. Generally used in pull (mask) mode, the LA-2 large animal respirometry system incorporates water vapor pressure and barometric pressure measurement for accurate compensation of regulated mass flow rates. Dilution compensation of oxygen and carbon dioxide analyzer readings is also supported, which can eliminate the need for any scrubber chemicals.

The LA-2 large 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. Methane analysis is also available. 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. The analysis of acquired data is uniquely fexible and can also be fully automated, if desired. The respirometry equations used in the system are state-of-the-art. Lifetime technical support by experts in respirometry is included.
