Product information

Specifications

Description

The fixed focus design of the Raman immersion optic provides long-term measurement stability along with superior signal performance which is essential for transferable, high-performance Raman measurements. Compatible with the Rxn-10 probe, the immersion optic uses no movable parts so it is always in focus. The Raman immersion optic is well-suited for use in reaction vessels, laboratory reactors, or process streams, and its wettable components resist corrosion in harsh environments.

Field of application

Pharmaceutical: drug substance unit operations, reaction analysis, crystallization, end-point detection, solvent swaps

Chemical: material identification, reaction analysis, polymerization, cross-linking, blending

Food & Beverage: blending, purification, natural and synthetic components

Development laboratory: versatile in situ analysis, feasibility studies, model development (or similar)

Benefits

Ideal for quick measurements of liquids, slurries, and semi-solids in a laboratory setting
Superior signal performance
Available in 1/4” and 1/2” diameters
No user-adjustable parts
Wettable components resist corrosion in harsh environments (including acidic solutions)
