Pion's Rainbow R6 Concentration Monitor: 

An in vitro analytical platform for dissolution and flux measurements of whole dose formulations using biorelevant volumes.

One of Pion's most popular products, the Rainbow R6, is our top-rated in-situ fiber optic concentration monitoring system.

If your application requires high accuracy and repeatability in concentration measurement, Rainbow R6 can accelerate your pharmaceutical formulation development with ease.

• Equipped with up to 8 independent fiber-optic channels, the Rainbow R6 provides high accuracy and repeatability in concentration measurements.
• The Rainbow R6 Concentration Monitor is used for early-phase compound screening, pre-formulation and formulation studies, and quality control.

The In-Situ UV Probe-Based Dissolution System

The Rainbow R6 provides concentration measurements in real-time. Removing delays between sample draw and analysis, the Rainbow R6 produces consistent, replicable results, whatever the media.

A sample measurement can be obtained in less than 5 seconds for each vessel, enabling unattended, extended assays. This provides the enriched data for very short sampling intervals required for immediate-release formulations.

Common Applications

• Real-time analysis of dissolution progress, regardless of dissolution media
• Generates more detailed profiles
• Simultaneous analysis for screening formulations ahead of bio-equivalence studies
