RamanRxn™ Probe Head for Flexible Laboratory-based Sampling

The RAMANRXN Probe filtered remote Raman probe head is suitable for laboratory / general purpose Raman sampling. This fiber-optically coupled probe is both compact and lightweight, which maximizes sample opportunities.

The RAMANRXN Probe is versatile enough to accept a wide range of sampling optics. Non-contact optics can be used to measure through windows, bottles, or simply at a convenient distance from a sample. Immersion (IO) and insertion optics are available for in situ Raman analysis of reaction vessels, automated laboratory reactors, extruders, or process streams.
