Oxylet ((new)) -

The system integrates several high-precision components to capture a holistic view of metabolic performance:

The system, developed by Panlab Harvard Apparatus , is a sophisticated modular platform designed for indirect calorimetry and metabolic monitoring in laboratory animals, primarily mice and rats. By measuring respiratory gas exchange and physical activity, Oxylet provides researchers with a comprehensive window into an animal's energy balance and metabolic health. Core Capabilities of the Oxylet System

The system automatically calculates energy expenditure using standardized formulas, typically expressed in to account for metabolic body weight. oxylet

The Oxylet gas analyzer (often the LE 405 model) measures oxygen consumption ( VO2cap V cap O sub 2 ) and carbon dioxide production ( VCO2cap V cap C cap O sub 2 ) at frequent intervals, such as every 2–5 minutes. Respiratory Quotient (RQ) Calculation: By dividing VCO2cap V cap C cap O sub 2 VO2cap V cap O sub 2

Advanced modules can track the exact weight of food and water consumed, allowing for the calculation of metabolic efficiency—how much body weight is gained per calorie ingested. Critical Applications in Research The Oxylet gas analyzer (often the LE 405

The Oxylet system is a staple in labs investigating obesity, diabetes, and metabolic syndrome. Key research areas include:

, researchers determine the Respiratory Quotient , which indicates whether an animal is primarily burning carbohydrates (RQ ~ 1.0) or fats (RQ ~ 0.7) for energy. Key research areas include: , researchers determine the

Integrated sensors or transducers (such as the LE 1335 Physiocage) detect movement variations to correlate metabolic shifts with physical activity or circadian rhythms.
