  • Brochure: NIRS XDS Transmission OptiProbe Analyzer – Robust measurement system for reaction monitoring of liquids in technical centers and pilot plant stations

The NIRS XDS Transmission OptiProbe Analyzer enables efficient determination of the composition of aqueous products, clear liquids, solvents and viscous samples. The instrument is equally suitable for use in technical centers or for at-line applications in the context of scale-ups of production processes. NIRS disposable glass vials are available for viscous samples, limiting cleaning costs to a minimum. The optionally available NIRS Vial Heater can be used to analyze samples at a temperature of up to 200 °C
