CaloWheel

The CaloWheel system is an automated running wheel for rats or mice suitable for measurements of metabolic parameters during physical activity ("exercise calorimetry").

The wheel is coupled to a motor with adjustable speed control.

The sealed housing has separate air inlet, air outlet and sample air connections and is coupled to a fully computer-controlled TSE calorimetry setup.

The calorimetry module of the TSE PhenoMaster / LabMaster platform features a user-friendly software that controls the experimental procedure and collects the measuring data. Measurement of O₂ consumption and CO₂ production during exercise allows the automatic calculation of a number of calorimetric parameters such as energy expenditure and respiratory exchange rate. Data are presented graphically and numerically and is available as an export file for statistical evaluation.

• The CaloWheel combines forced activity wheel running with open-circuit indirect calorimetry
• Airtight acrylic housing with reduced volume for optimum calorimetric results plus maximum visibility
• Automatic recording and analyzing of metabolic parameters: VO₂, VCO₂, Respiratory Exchange Rate (RER), Energy Expenditure (EE)
• Gas sensor technique
• Specific motor with manually adjustable speed
