Metabolic - O2/CO2/VO2/VCO2/RQ

Fusion Metabolic System uses Open Circuit Calorimetry and is ideal for measurement of Oxygen Consumption and Carbon Dioxide Production in lab animals in an open Field or in a Treadmill. With Fusion Software, the system monitors, records and plots O2, CO2, VO2, VCO2, RQ measurements every second. Archived Experiments can be reanalyzed and exported to any spreadsheet/statistical package for further analysis. Up to eight animals can be simultaneously monitored. Two, four, and six animal systems are also available.

The Metabolic System is comprised of a Metabolic Analyzer, Oxygen Analyzer, Carbon Dioxide Analyzer, a multi channel Flow Controller, Windows XP/Vista Based Fusion Software and air-tight Cages or Treadmills. The Metabolic System measures and stores O2/CO2 content and Air Flow of one to eight enclosed environments. The System also generates and stores VO2, VCO2 and RQ Data for each subject. A diagnostics mode allows the user to perform a hardware test on the system to insure proper operating conditions. The Oxygen Analyzer uses a Zirconia Sensor and has a built in sample pump and flow controller. The carbon dioxide analyzer has a dual beam sensor and requires no calibration. The flow controller has independent pumps for each channel as well as a mass flow meter. Flow Ranges are adjustable up to 5 L/min for small animals (Mice/Rats) and up to 25 L/min for larger animals (Cats/Dogs/Pigs). The System does not require the use of Drierite .

The animal is placed in an air tight cage . Ambient air is pumped through the cage. The amount of air entering the cage is precisely measured by a Mass Flow Meter. Air entering and leaving each cage is monitored for O2 and CO2 content by zirconia and infrared sensors. Both sensors are very accurate and maintenance free. Unlike electrochemical cells, zirconia cells provide higher accuracy and do not have to be replaced. Since the System does not require the use of Drierite, multi day experiments can be easily run without user intervention. All Experiment Data is continuously monitored, displayed and stored for future analysis.
