NEW BREATH OF PRECISION: GEMINI REDEFINES SMALL ANIMAL RESPIRATORY RESEARCH

Compact & easy for small-animal plethysmography & metabolic monitoring

The GEMINI O₂ & CO₂ Monitor from CWE Inc. is transforming small-animal calorimetry (rat and bigger)—delivering the high-resolution gas analysis researchers need, without the bulk, complexity, or cost of traditional systems.

Designed for open-circuit indirect calorimetry, GEMINI eliminates the need for face masks and pneumotachs, enabling researchers to measure metabolic signals directly from sealed chambers where airflow is precisely controlled.

As respiration subtly alters gas composition, GEMINI’s high-resolution digital sensors capture these micro-differences with outstanding stability. This level of sensitivity is essential for calculating key metrics like VO₂, VCO₂, Respiratory Exchange Ratio (RER), and Energy Expenditure (EE).

KEY FEATURES AT A GLANCE

COST EFFECTIVE, ALL-IN-ONE

All major functions (O₂/CO₂ sensing, display, calibration, sampling control) are built into a single unit that integrates with your current lab equipment.

All-digital interface for quick setup
Adjustable alarms for CO₂ levels and respiratory rate

COMPACT, EFFICIENT DESIGN

Small footprint. Optional rack-mount kit available
Ideal for both dedicated calorimetry chambers and general-purpose lab setups, including those used in plethysmographic experiments

HOW THE GEMINI MONITOR STANDS APART FROM TRADITIONAL SYSTEMS

GEMINI MONITOR	Other Monitors
✅ All-in-one, compact design (32 cm wide)	❌ Bulky, multi-module setups
✅ No masks or pneumotachs required	❌ Often requires invasive headgear
✅ Digital O₂/CO₂ sensors with push-button ZERO	❌ Manual calibration & drift issues
✅ Integrated waveform display & pressure correction	❌ Separate modules, complex setups
✅ Low sample flow requirement	❌ High flow rates needed for accuracy
✅ Cost-effective & lab-friendly	❌ Expensive with higher maintenance load

APPLICATIONS ACROSS DISCIPLINES

The GEMINI Monitor supports a broad range of small-animal research needs and is ideal for:

Metabolic physiology
Pharmacology and drug development
Toxicology and exposure studies
Respiratory control research
Thermal and environmental adaptation
Whole-body plethysmography, where accurate chamber-based gas analysis is essential

Its flexibility, precision, and ease of integration make it especially well-suited for longitudinal and high-throughput studies where subtle metabolic and respiratory changes are being monitored.

EASY SETUP FOR BUSY LABS

GEMINI isn’t just precise. It’s practical. By eliminating complex plumbing, invasive gear, and multi-box systems, it reduces cost, setup time, and the chance for error. It gives labs of any size the power to uncover subtle metabolic differences with confidence and clarity—all in a streamlined, integrated platform.
