Flow-Through Cells with Optical Oxygen and Temperature Sensor
- Flow-through cells with integrated contactless optical oxygen and temperature sensor
- Luer-lock with tubing adapters
- Measures simultaneous temperature and oxygen in gas or aqueous liquids
- For True Temperature Compensation of integrated Oxygen Sensor
The optical temperature sensors from PyroScience are based on an innovative technology utilizing temperature-sensing properties of luminescent indicators. The combined flow-through cells have an integrated optical temperature and oxygen sensor for contactless measurements in gaseous or liquid samples flowing through the cell. The cell is equipped with Luer-lock connectors on both tubing ends. The included set of Luer-lock adapters allows direct connection of tubings with ca. 3-4 mm inner diameter. Importantly, the combined contactless temperature and oxygen sensors are fully compatible with the multi-channel FireSting devices from PyroScience, to which the flow through cell can be connected with two optical fibers (see accessories below). The optical temperature sensor in the combined flow-through cells can be used for true temperature compensation of the integrated oxygen sensor for high precision measurements.
- For oxygen measurements in gases and liquids pumped through the cell (inline measurements)
- Oxygen monitoring in a gas flow, e.g. at the outflow of a bioreactor
- Oxygen monitoring in flowing liquids e.g. in bioreactors, in- and outflow of an experimental set-up containing a sample (e.g. sediment core, biofilm, etc.)
