Sterile Oxygen Flow-Through Cell


  • Flow-through cell with integrated optical oxygen sensor
  • Sterilized using 25kGy beta-irradiation
  • Luer lock adapters for ca. 3.2 or 4.8 mm ID tubings
  • Works in gas (%oxygen) and liquids (DO)

These flow-through cells (PU=4 pieces) have an integrated oxygen sensor for continuous measurements of gaseous or aqueous liquid samples pumped through the cell. The cell consists of a Luer-lock T-Connector with a removable oxygen probe. The Luer-lock connectors allow direct connection of tubings with 3.2 or 4.8 mm inner diameter.

Standard range. This sensor is specified for an optimum measuring range of 0 to 500 hPa oxygen (0 -250% air saturation). However, without specifications, it is possible to measure in up to 1 bar pure oxygen/100% oxygen saturation/100% oxygen. For detailed specifications, see the respective pdf file in the Downloads tab.

Optical isolation. For applications at high ambient light (e.g. direct sunlight, illuminated samples) and in fluorescing / light-sensitive samples, an additional optical isolation (-OI) protection layer is added to the sensor surface to reduce enhanced sensor aging and to avoid interference with the oxygen measurements

Sterile sensor. This sensor was sterilized using 25kGy beta-radiation and is delivered in separate sterile packagings.
