小鼠用潮氣末二氧化碳分析儀 MicroCapStar End-Tidal CO2 Monitor For Mice

產品型號:
廠牌名稱: CWE
MicroCapStar潮氣末二氧化碳分析器提供準確潮氣末或動物小老鼠的過期二氧化碳的連續測量。它具有非常低的樣品量要求,快速的反應時間和長期穩定性。呼吸率(respiratory rate, RR)是使用CO2的波形的偏移來計算。二氧化碳和RR測量,以及在呼氣末值的趨勢圖中,顯示圖形的液晶螢幕上。

產品特點

The microCapStar End-Tidal Carbon Dioxide Analyzer provides accurate end-tidal or continuous measurement of expired CO2 in animals as small as mice. It features very low sample flow requirements, rapid response time, and long-term stability. Respiratory rate (RR) is computed using the excursions of the CO2 waveform. The CO2 and RR measurements, as well as a trend plot of the end-tidal values, are displayed on the graphics LCD screen.

The heart of the microCapStar is a temperature-controlled infrared CO2 sensor. Low sample flow and rapid response is achieved with a carrier gas system employing digitally-controlled active flow management. This technique automatically maintains the ratio of carrier flow to sample flow, which is essential for accurate measurements. The heated measurement cell prevents water condensation, even during long-term measurement sessions. The standard sample tubing set is 1m long, but lengths over 2.5m are possible.

The front-panel display shows CO2 concentration (either instantaneous or ETCO2) in either percent or mmHg, and a 5-minute trend plot of ETCO2.. Calibration is performed with a single calibration gas and room air. An adjustable ETCO2 alarm provides a warning when end-tidal values fall out of a user-adjustable preset range. All adjustments are performed using a single knob. Built-in diagnostics monitoring warn of plugged sample tubing or other fault conditions.

The advanced features, reliability, and ease of operation of the microCapStar make it the perfect companion to our Small Animal Ventilators for monitoring respiratory status. With the AVS-1 Advanced Ventilator System, it can be used to control end-tidal CO2. An accessory pack containing spare low-volume sample tubing and a variety of connectors and fittings is included with the instrument. A range of accessories is available to ensure easy setup and convenient operation. 

CO2 monitoring is widely recognized as an important measure of the respiratory status of experimental animals. It is useful in setting ventilator parameters, and serves to gauge depth of anesthesia in unassisted, spontaneously breathing animals as well. The microCapStar extends this important technique to the realm of small experimental animals.
