Dissolved oxygen sensors

A choice of oxygen sensor types are available to suit a wide variety of in vitro and in vivo applications, schematically represented below.

Sensors with integrated thermocouple sensor allow for automatic temperature-compensation of pO2 readings.

'BF/O' - pO2-only sensor

Format: Single fibre-optic.
Applications: Virtually any tissue type; in vitro O2 monitoring; minimally invasive, rapid response times, MRI compatible.

Requires: OxyLite or OxyLab pO2 monitors only.
Product code: BF/O/E
Tip diameter: ~250 μm
Cable length: 2 m

'BF/OT' - pO2/ Temp sensor

Format: Single fibre-optic + thermocouple.
Applications: As for BF/O where temperature fluctuations are expected; partial MRI-compatibility.

Requires: OxyLite or OxyLab pO2 monitors only
Product code: BF/OT/E
Tip diameter: ~350 μm
Cable length: 2 m

'NP/O' - Needle-encased pO2-only sensor

Format: BF/O sensor encased within robust 23G surgical steel needle. Oxygen detection via lateral 'windows' distal from the sensor tip. Larger tissue sampling area/volume.
Applications: Various, requiring greater sensor robustness.

Requires: OxyLite or OxyLab pO2 monitors only.
Product code: NP/O/E
Tip diameter: ~630 µm / 23G
Cable length: 2 m

'LAS/O' - Shielded 'large area' pO2-only sensor

Format: BF/O sensor partially shielded within robust 23G surgical steel enclosure. Oxygen detection via lateral 'windows' distal from the sensor tip. Very large tissue sampling area/volume.
Applications: Various, requiring representative pO2 monitoring across an extended tissue sampling area/volume.

Requires: OxyLite or OxyLab pO2 monitors only.
Product code: LAS-1/O/E or LAS-8/O/E
Tip diameter: ~630 µm / 23G
Cable length: 2 m
