Oxygen sensor FTCH-PSt1

laboratory

The oxygen microsensor housed in a flow-through cell is optimized for a fast response time (t90< 1 sec in gas, < 5 sec. in liquid). The microsensor with a tip size from < 50 µm to 140 µm is integrated in a sleeve made of Teflon® tightened with a silicone rubber, which is mounted to a T-connector. The liquid volume inside the FTCH is about 310 µL. External tubing with an inner diameter of 1.6, 2.3, and 3.2 mm can be connected via Luer-Lock adpaters. Liquids (e. g. water, blood, etc.) can be pumped through the cell. The FTCH-PSt1 has a measurement range of 0 – 50 % oxygen, with a detection limit of 0.05 % oxygen. Perfusion monitoring in smallest volumes High temporal resolution (< 5 sec.) No consumption of oxygen Measures in liquids as well as in the gas phase 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 - Ethylene oxide (EtO) 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
