Oxygen sensor IMP-PSt7

CO2pHcalibration

This optical oxygen microsensor can be applied in various customized applications. The tiny probe has a tip size < 50 µm to 230 µm while the outer diameter ranges from 230 µm to 900 µm. The microsensor tip is not mounted into any additional housing. The bare glass fiber tip can be mounted to your own housings, steel tubes and micro respirometer chambers etc. The small outer diameter even allows insertion into implantable Venflon-tubes. Moreover the microsensor can be deployed in sealed containers to measure the oxygen content directly. The IMP-PSt7 has a measurement range of 0 – 100 % oxygen, with a limit of detection of 0.03 % O2. High spatial resolution (< 50 μm) High temporal resolution (t90 < 3 sec.) Integration into customized housings and set-ups No consumption of oxygen Measurement in headspace & liquids Properties - - Compatibility - Aqueous solutions, ethanol, methanol No cross-sensitivity - pH 1 – 14 CO2, H2S, SO2 Ionic species Cross-sensitivity - Organic solvents, such as acetone, toluene, chloroform or methylene chloride Chlorine gas Sterilization procedure - Steam sterilization Ethylene oxide (EtO) Recalibration recommended Cleaning procedure - 3 % H2O2 Ethanol Soap solution Calibration - Two-point calibration with oxygen-free environment (nitrogen, sodium sulfite) and air-saturated environment Storage stability - 60 months provided the sensor material is stored in the dark at room temperature
