In-situ fiber optic Uv-vis spectrometer for dissolution studies
In pharmaceutical research, accurately predicting how a drug will dissolve and be absorbed in the body before proceeding to animal studies can be challenging. Ensuring that lead compounds can be optimized with confidence requires precise and rapid data collection.

Measure drug dissolution and absorption in real time
The Rainbow R6, developed by Pion, is an advanced in-situ fiber optic UV-Vis spectrometer designed for dissolution, absorption, flux, and solubility studies. This system offers real-time concentration measurements, removing delays between sample draw and analysis. With sample measurements available in less than 5 seconds, the Rainbow R6 facilitates unattended, extended assays and ensures enriched data for very short sampling intervals, which are crucial for immediate-release formulations. Its versatility allows seamless integration with various FLUX apparatuses to conduct absorption and flux assays. Additionally, the Rainbow R6 supports various Pion software such as Pion Predictor for advanced data processing and AuPRO for early-stage compound screening and dissolution data refinement.
