    Optical pCO2 Monitoring in Biotechnology & the Pharma Industries

    In order to ensure stress-free cultivation conditions pCO2 needs to be monitored and controlled especially in cell culture. But also in bacteria and yeast culture the fiber optic CO2 measurement systems by PreSens offer a convenient solution, as continuous carbon dioxide monitoring and control can be conducted without sampling. Due to the small sensor size and the possibility of non-invasive measurement through transparent vessel walls, optical carbon dioxide measurement systems are ideally suited for culture monitoring in small-scale cultivation vessels, e. g. shake flasks or cell culture flasks. Flow-through cells with integrated CO2 sensor even allow perfusion monitoring in bioreactor bypasses. Our optical CO2 measurement devices are suited for culture monitoring applications from microliter- up to production-scale. Combined with non-invasive O2 and pH measurements your analyses will profit from online optical carbon dioxide monitoring, whether it is in bioprocess development, or simply following metabolic activity of microorganisms and cells.

    Optical pCO2 Measurements in Life Sciences & Medical Research

    The 2-dimensional assessment of CO2 distributions offers whole new insights in many life science and medical research applications. Our CO2 imaging devices allow to follow gradient development over a


    whole area of the sample surface or a cross section, and can also be used for contactless measurement through transparent vessel walls for carbon dioxide control in most different cultivation vessels. The information about CO2 distributions over whole area can give valuable information when assessing engineered tissue culture, microfluidic chips or monitor CO2 in perfusates for tissue and organ transplants. Together with our oxygen and pH measurement devices, online optical carbon dioxide measurements give valuable information about ongoing processes.

    Biological & Environmental Studies Profit from Optical CO2 Monitoring

    Especially in times of climate change CO2 is an important parameter to monitor. As our sensors are meant for measurements in liquids, they can ideally be applied for experiments in sea water e. g. ocean acidification studies. Invasive probes with stainless steel fitting can directly be inserted in liquid samples and pCO2 concentrations can be assessed in no time. 2D visualization of CO2 gradients with our carbon dioxide imaging system can give whole new information in many applications from animal and plant physiology to experiments in sediments and flume chambers. Furthermore, customized fiber optic CO2 measurement devices are offered, so PreSens can deliver you the sensor solution you need.
