Probe features new type of infrared light source that solves the challenges of high temperature durability and limited lifetime


Vaisala, a global leader in environmental and industrial measurement, has launched the CARBOCAP Carbon Dioxide Probe GMP231. The GMP231 is designed to provide incubator manufacturers with accurate and reliable carbon dioxide measurements and sterilisation durability at high temperatures.

The probe is based on Vaisala's patented CARBOCAP technology and features a new type of infrared (IR) light source, Microglow, which further enhances the performance of CARBOCAP sensors. Microglow represents next generation IR technology that solves many of the challenges that affect traditional infrared sources, or incandescent light bulbs, such as high temperature durability and limited lifetime.

Thanks to these advances, Vaisala says, the GMP231 offers superior durability and allows for heat sterilisation temperatures of up to 180°C. This enables easier and more complete sterilisation of the incubator with the probe in place, removing the need to decontaminate the probe separately. This saves the end-user time and further reduces the risk of contamination.

The GMP231 has been developed together with a major industry partner and is designed for CO2 incubator OEMs. Many life science applications, such as growing and storing cell cultures, require the CO2 concentration to be measured and controlled. The required CO2 atmosphere, along with the temperature and humidity, is commonly generated with a special climate chamber called a CO2 incubator. Incubators are regularly sterilised – for example, before new samples are put inside. An incubator equipped with the GMP231 provides a reliable and carefree CO2 measurement solution.
