BioOxy Optical Oxygen Sensor

The BioOxy 50μm active area diameter tip expands researchers’ capabilities of discovery with sensing O2 in critically small spaces.   

Features

• BioOxy does not consume oxygen during measurements
• Similar performance overall at a lower cost.  This helps lower research or operational expenses compared to competitive consumable sensors
• BioOxy can be gamma sterilized

The BioOxy Couples directly to either the Fiber Optic OXY-MICRO Microsensor Oxygen Meter or the FLOX-Oxygen monitoring System.

Options

Features

• Oxygen detection using the phase shift between a reference signal and measured signal
• Common sterilization procedure via gamma radiation, ethanol, paracetic acid, ethylene oxide
• Easy cleaning procedure with 3% H₂O₂, ethanol, or common soap solution
• Compatibility with ethanol, methanol, and isopropanol
• No cross-sensitivity for organic solvents such as acetone, toluene, chloroform or methylene chloride and any chlorine gas
• Available with SMA or ST connector
• Sensing tip diameter, ~50μm

Benefits

• Designed for use in gaseous and aqueous solutions
• Easy calibration via a two-point calibration with an oxygen-free environment (nitrogen, sodium sulfite) and an air-saturated environment
• Fast response time t₉₀ ≤ 3 seconds (in gas phase)  t₉₀ ≤ 30 seconds (in pure water)
• Retractable up to 10mm
• No oxygen consumption during measurements

Applications

• Oxygen measurement in small samples
• Bioprocess control

The BioOxy is ideally adapted for examination of small sample volumes thanks to its miniature sensor tip diameter of less than 50μm. The BioOxy is well suited for long-term measurements and biotechnological applications. The signal does not depend on the flow rate of the sample and the measurement principle requires no contact.

The physical principle is based on quenching of luminescence, which is caused by the collision between molecular oxygen and a luminescent dye molecule in the excited state. There is a direct relationship between the measured phase angle and oxygen concentration.  The phase angle decreases when oxygen is present in your sample.  The transfer of the emitted light signal is done optically using high quality fused silica fibers, ensuring a contact performance lot-to-lot.
