Real-Time RER: Fasting & Refeeding Effects in Mice.
Witness the power of comprehensive metabolic data in a single window! This graph showcases the impact of fasting, refeeding, and temperature on mice in real time. Observe the evident decrease in Respiratory Exchange Ratio (RER) during fasting, followed by the rise upon refeeding. This level of detailed insight is achieved through our high-resolution (1-second) indirect calorimetry system, capturing every data point throughout the experiment.

Powerful PhenoMaster Software.
PhenoMaster software empowers researchers to achieve breakthrough results in metabolic research. Our intuitive interface guides users in optimizing cage settings, ensuring the accuracy and consistency of your data. PhenoMaster connects existing modules like activity, exercise, and ingestive behavior trackers, allowing you to establish robust correlations between various physiological parameters.
This unmatched level of adaptability extends beyond the cage. CaloSys Pro integrates with special gas sensors, allowing you to share them seamlessly across diverse research settings – from standard home cages to metabolic wheels or treadmills. This flexibility empowers researchers to conduct multifaceted metabolic studies tailored to specific needs.
