    Sterilizable IR-ATR Fiber Probe for Bio- Process Monitoring

    • High throughput in any part of Near & Mid InfraRed-spectrum
    • ATR-tip shaped for immersion in liquid fl ow without dead zone
    • Flexible and robust for industrial applications in harsh environment
    • Compatible with all spectrometers and automated process-interfaces

    Sterilizable ATR Fiber Probe is a new product of art photonics’ FlexiSpec® product line. This ATR Probes are produced with any type of ATR element and for any type of FTIR spectrometers.
    Unique Shaft-in-Shaft design enables use of FlexiSpec® ATR Probe in Bio process where sterilization is required without having to forgo the renowned advantages of MID-IR FTIR spectroscopy.

    With our new design you don’t need to take out all the probe from the reactor during the reactor sterilization process. Just detach the fiber assembly whereas the sensitive tip can remain fixed in the reactor and be sterilized together with it.


    • Reaction Monitoring in real time
    • Process Analytical Technologies (PAT)
    • Remote Polymerization Control
    • Crystallization Process Screening 
    • In-situ IR-Spectroscopy for PAT in Chemical, Petrochemical, Atomic, Biopharmaceutical & Food Industry
