CWE CapStar - Model 100 -Fast and Accurate CO2 Monitor for Rats and Larger Animals
The CapStar-100 End-tidal CO2 Monitor offers precise and fast monitoring of carbon dioxide levels in rats and larger animals. Central to its design is a compact infrared analyzer noted for its stability and minimal maintenance requirements. It features a heated measurement cell crucial for preventing water condensation. Its graphic LCD provides CO2 concentration readings in both percent and mmHg, with options for breath-by-breath peak end-tidal and continuous rapid response monitoring. A single calibrated gas and room air simplify the calibration process. Designed for ease of use, it pairs effectively with SAR-830 series Small Animal Ventilators. Its capabilities extend to monitoring unassisted animals, making it suitable for a variety of research scenarios. The monitor has a response time capable of handling respiratory rates up to 100 breaths per minute. Accessories for convenient operation are available, and sampling rates allow accurate monitoring even for small animals like rats.

The heart of the instrument is a miniature infrared analyzer with exceptional stability, low maintenance, and a linear output. The heated measurement cell prevents water condensation. in minutes. The graphic LCD display shows CO2 concentration in percent or mmHg, and allows breath-by-breath peak end-tidal reading (ETCO2) or continuous rapid response. Calibration is performed with a single calibrated gas and room air.
The reliability and ease of operation of the CapStar-100 make it the perfect instrument for routine respiratory CO2 monitoring. It is the natural companion to our SAR-830 series Small Animal Ventilators for monitoring respiratory status. With the AVS-1 Advanced Ventilator System, it can control end-tidal CO2. It can also be used to monitor unassisted animals. Gas sampling rates of less than 30ml/min can be used, making it possible to monitor animals as small as rats. The fast response time of the CapStar-100 allows end-tidal response plateaus with respiratory rates of 100 breaths/min.
A range of accessories is available to ensure easy setup and convenient operation. An accessory pack containing sample tubing, moisture traps, and Nafion® moisture-absorbing sample tubes is included with the instrument.
