Advanced Tail-Cuff Occlusion Technology
Designed for cardiovascular and metabolic research, the NIBP system uses a dual-cuff setup for precise and repeatable blood pressure measurements. The first cuff at the tail base occludes the artery, while the second, placed further down, senses arterial pulsation. This configuration ensures accurate readings of systolic, diastolic, and mean arterial pressure. Prioritizing animal welfare, the system pre-warms the tail, delivering reliable results without invasive procedures or full-body heating.

Accurate Data Visualization
The NIBP system continuously tracks blood pressure changes to deliver a reliable reading. During each measurement, users can review signals from both cuffs to evaluate and accept the results. The system displays the data on-screen, which can be saved or exported. Output includes numerical pressure values in mmHg, along with graphical representations of the pulsation sensor signals and the pressure curve from the occlusion sensor.

High-Capacity Throughput System
Engineered for maximum efficiency, the automated system allows users to schedule precise measurement times for each subject. Blood pressure readings take just 16 seconds to complete. Subsequent measurements can be set 30 seconds apart, ensuring seamless data collection. With its streamlined process and customizable settings, the NIBP is an ideal solution for high-throughput research labs looking for fast, accurate results.

Features and Benefits

Precision-Driven Calorimetry
The Universal Oxymax Indirect Calorimetry system delivers precise O2 and CO2 measurements in sealed metabolic cages with unmatched accuracy. Its modular design suits both large and small setups, while its fully automated, turnkey system ensures easy maintenance. With adjustable airflow from 0.5 to 3 liters/minute, Oxymax provides optimal resolution or certainty as needed. It captures O2 and CO2 data at 10Hz, offering high-resolution measurements to filter noise and achieve ultra-fast cage response times.
Oxymax supports 3 oxygen sensor types to cover all possible applications. A non-dispersive infrared CO2 sensor virtually eliminates drift, reducing recalibration needs.
Dependable Humidity Control for Consistent Results
Building on a tradition of precise humidity management, Oxymax features a cutting-edge 2-stage sample drying method that effectively eliminates all moisture from air samples. This advanced approach ensures that only oxygen, carbon dioxide, and nitrogen are measured, adhering to the best practices for indirect calorimetry in research and preventing humidity from skewing recorded oxygen values.
Rapidly removing humidity can pose a significant engineering challenge. While humidity correction—measuring and back-calculating humidity—may seem like a simpler alternative, it relies on stable temperatures and often fails during rapid fluctuations. In experiments with manipulated ambient temperatures, the humidity correction technique lacks proper temperature compensation to accurately track VO2, leading to questionable RERs. Oxymax’s precision-engineered drying method is the best on the market that ensures accurate oxygen tracking regardless of temperature changes, delivering reliable O2/CO2 measurements while matching or exceeding the temporal resolution and data density of humidity corrected systems.
