Benefits

Self-contained benchtop system that is resistant to stray light and fiber bending
The unit's simplicity of setup and control, stability, and sensitivity make it ideal for long-term studies.
You have various alternatives thanks to three coatings for probes and patches.

Applications

Applications for oxygen sensing that need stability and sensitivity to drift that must be left alone for extended periods of time
Check the O2 partial pressure in aqueous solutions, vapors, and gases as well as in non-aqueous vapors and solutions
Check for oxygen traces in gases and liquids

The FLOX instrument measures the lifetime, phase, and intensity of fluorescence. For simple experimental setup and control, it uses filter-based wavelength selection along with LED excitation and photodiode detection.

Self Contained Unit

Due to its small size and self-contained design, it is resistant to fiber bending and stray light. Also, it features low optical and electrical crosstalk, a large dynamic range of optical intensity, low drift and phase noise, and other positive characteristics.

FLOX is particularly helpful in oxygen sensing applications where stability and sensitivity to drift are critical and sample setups must be left in place for extended periods of time.

Excellent for Long Term Study, Simple Setup

The new oxygen detecting system uses filter-based wavelength selection along with LED excitation and photodiode detection to evaluate fluorescence lifespan, phase, and intensity. The system is easy to configure and use. This device is perfect when stability and sensitivity to drift are crucial for your oxygen sensor experiment. It is ideal for uses when sample setups need to be left alone for extended periods of time.

For Patches and Probes, There are Three Coating Options

The transducer materials, which are put to the tips of optical fibers or to substrates like patches or cuvettes, are what make up optical sensors since they alter their optical properties in response to particular analytes in their immediate surroundings.

OXY — A fiber optic fluorescence probe with a specially coated oxygen sensing tip serves as the industry-standard oxygen sensor for measuring the partial pressure of oxygen in gases and aqueous solutions.

HIOXY is made to measure the partial pressure of oxygen in non-aqueous vapors and solutions. Oils, alcohols, and vapors and liquids made of hydrocarbons are all compatible with the sensor coating chemistry.

Monitoring oxygen traces in gases and liquids can be done using FOSPOR, a new kind of very sensitive sensor coating.

The low-power, highly sensitive, reversible, and stable oxygen sensor probes are perfect for remote monitoring. The probe tips' thin layer prevents oxygen from being consumed, enabling constant contact with the sample. They are perfect for viscous samples and unaffected by changes in pH, ionic strength, salinity, or biofouling.
