Flow-Through Cells with Oxygen Sensor

  • Flow-through cells with integrated contactless optical oxygen sensor
  • Luer-lock with tubing adapters
  • Works with gas (%O2) and with liquids (DO)
  • No oxygen consumption
  • Negligible drift
  • >3 years shelf time
  • Trace oxygen versions available

The flow through cells have an integrated oxygen sensor spot, allowing precise contactless oxygen measurements of gaseous or liquid samples flowing through the cell. The flow-through cells are available as a small version OXFTC and as a large version OXFTC2. The cell is equipped with luer-lock connectors on both tubing ends. A set of luer-lock adapters is included allowing direct connection of tubings with ca. 1-2 mm inner diameter (OXFTC) or ca. 3-4 mm inner diameter (OXFTC2). The flow through cell is connected via an optical fiber to an optical oxygen meter from Pyro Science (see accessories below).

Trace range versions. A trace range version TROXFTC is available for high precision measurements close to 0% O2. It offers about 5x higher resolution compared to the normal range version. The recommended measuring range is 0-10 %O2. However, calibration at ambient air (21% O2) is possible, ensuring a straightforward calibration without the need of special calibration standards.
