The Vaisala Carbocap Carbon Dioxide Probe GMP231 has been released.

Many life science applications, such as growing and storing cell cultures, require the carbon dioxide concentration to be measured and controlled. The required carbon dioxide atmosphere, along with the temperature and humidity, is commonly generated with a special climate chamber called a CO2 incubator. Incubators are regularly sterilized, for example before new samples are put inside.

The Vaisala Carbocap Carbon Dioxide Probe GMP231 is designed to provide incubator manufacturers with accurate and reliable carbon dioxide measurements and sterilization 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.

With Microglow, the performance of Carbocap sensors has been even further improved. Microglow represents next generation infrared technology that solves many of the challenges (e.g. high temperature durability and limited lifetime) that impact traditional infrared sources, or incandescent light bulbs. Thanks to these advancements, the GMP231 offers superior durability and allow for heat sterilization temperatures of up to 180 °C. This enables easier and more complete sterilization 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.
