Our easy to use, peel-and-stick RedEye indicator patches measure oxygen safely and non-invasively in sealed packaging and containers used in medical, pharmaceutical and food applications. Patches can be applied to flexible substrates of essentially any shape or size, or adhered to a transparent vessel or process line. Using a combination of proprietary sensing material and measuring technologies, RedEye patches enable rapid, quantitative determination of oxygen levels.
RedEye® coatings are capable of monitoring low levels of oxygen in gas (0.01%) and dissolved oxygen in liquids (4 ppb), as well as the higher oxygen levels present in cell culture and respiratory monitoring.
Non-invasive Monitoring with RedEye® Indicator Patches
Measurements of sensor patch fluorescence are made quickly and conveniently through the container wall using a fiber optic probe. This opens the door to applications that require monitoring of closed systems, such as biological processes, food and beverage packaging, and laboratory apparatuses.
Patches are interior to the sample packaging, container or chamber, while the probe remains outside.
- Measure patches using an RE-BIFBORO-2 fiber probe, NeoFox measurement instrument, and NeoFox Viewer software.
- Small patches may be better for small vessels.
- Larger patches are less alignment-sensitive, and allow for more probe and vessel movement.
- Are available in all sensor formulations.
- Flexible patch material allows adhesion to curved surfaces.
- Silicone adhesive maintains optical clarity and mechanical hold to glass and plastics for months in aqueous environments; tested at pH 1 and 11, in DI water, and seawater.
- Fast response (<5 seconds without overcoat, <20 seconds with overcoat) in both gas and liquid media.
- Custom diameters or shapes available upon request.
Optional Silicone Overcoat:
- Excludes ambient light and cross-fluorescence.
- Eliminates interference from sample color and turbidity.
- Protects the sensor from biofouling interference and chemical degradation.
- Increases response time; use only to mitigate interfering factors described above.
- The overcoat applied to our FOSPOR chemistry has been USP Class VI certified.
