End-tidal peak or continuous readings

Low sample flow requirements

Accurate and stable monitoring

Linear output signal for recording

Works with ventilated or unassisted animals

The End-Tidal Carbon Dioxide Analyzers provide quick and accurate end-tidal or continuous measurement of expired CO2 in mice or rats. Respiratory rate is computed using the excursions of the CO2 waveform and displayed on the LCD screen.

Analyze End Tidal CO2 in rats with the CapStar-100 or in mice with the MircoCapStar.

The heart of the CapStar Series of Analyzers is a temperature controlled, miniature infrared CO2 sensor with digital output. A carrier gas system automatically maintains the ratio of carrier flow to sample flow, and results are obtained with low sample flow and rapid response. The heated measurement cell prevents water condensation.

CO2 concentration may be displayed in percent or mmHg. An alarm sounds when end-tidal values fall out of adjustable range. All adjustments are performed digitally using a single knob. Windows-based monitoring software in included, as well as an accessory pack of tubing, connectors and fittings.
