Contactless Oxygen Sensors
Oxygen Sensor Spots
Oxygen sensor spots allow oxygen measurements in closed sample containers with contactless read-out through a transparent window (glass, acryl glass) with special adapters and optical fibers for all types of fiber-optic meters from PyroScience. This enables incubations in closed systems, preventing potential contamination and simplifying oxygen monitoring without sampling, also in combination with pH and temperature sensor spots.

Oxygen Flow-Through Cells
These flow-through cells 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.

Oxygen Sensor Vials
Based on the contactless sensor technology, PyroScience offers ready assembled vials with integrated sensor stripes for all supported analytes. The glass respiration vials have screw caps with a septum, and are available with ca. 20mL (uncalibrated) volume. Adapter rings allow an easy fixation of optical fibers for read-out with optical meters from PyroScience for incubations in closed vials. The elongated shape of the sensor spots allows also measurements at different heights within the vial using several fibers/adapter rings in parallel.

Oxygen Nanoprobes
The oxygen nanoprobes OXNANO allow dissolved oxygen (DO) measurements in liquid samples within closed transparent systems (plastic or glass). They are perfectly dispersible in aqueous solutions or culture media. A simple batch calibration of the nanoprobe dispersion allows read-out at various locations along the sample container or in different samples containing the same dispersion. They are ideally suitable for contactless measurements of fast processes in small sample volumes and within complex geometries.
