FLOX is a device for measuring fluorescence lifetime, phase and intensity. It uses LED excitation and photodiode detection with filter-based wavelength selection for easy experimental set-up and control.

FLOX is especially useful for oxygen sensing applications where stability and sensitivity to drift is important and where sample set-ups must be left undisturbed for long periods of time.

FLOX is a device for measuring fluorescence lifetime, phase and intensity. It uses LED excitation and photodiode detection with filter-based wavelength selection for easy experimental set-up and control.

Self contained unit

The compact, self-contained unit makes it invariant to fiber bending and stray light. It also has a wide dynamic range of optical intensity, as well as low optical and electronic crosstalk, and low drift and phase noise.

FLOX is especially useful for oxygen sensing applications where stability and sensitivity to drift is important and where sample set-ups must be left undisturbed for long periods of time.

Easy setup, great for long term studies

The new oxygen sensing system measures fluorescence lifetime, phase and intensity, using LED excitation and photodiode detection with filter-based wavelength selection. The system is simple to set-up and control. When stability and sensitivity to drift are important in your oxygen sensing experiment, this unit is ideal. It is perfect for applications where sample set-ups must be left undisturbed for long periods of time.

Three coatings available for probes and patches

The optical sensors consist of transducer materials, applied to the tips of optical fibers or to substrates such as patches or cuvettes, which change optical properties in response to specific analytes in their immediate environment.

OXY–The standard oxygen sensor designed for monitoring oxygen partial pressure in gas and aqueous solutions is a fiber optic fluorescence probe with a proprietary oxygen sensing coated tip.

HIOXY–Designed for monitoring oxygen partial pressure in non-aqueous vapors and solutions. The sensor coating chemistry is compatible with oils, alcohols, and hydrocarbon-based vapors and liquids.

FOSPOR–A new generation of highly sensitive sensor coating can be used for monitoring traces of oxygen in gas and liquids.

The oxygen sensor probes are low-power and offer high sensitivity, reversibility and stability, ideal for remote monitoring. The thin coating on the probe tips consumes no oxygen, allowing for continuous contact with the sample. They are ideal for viscous samples and are immune to interference caused by pH, ionic strength or salinity fluctuations or biofouling.

 

FLOX software displays oxygen measurements on a connected PC.
