Rainbow

The UV fiber optic-based Rainbow® Dynamic Dissolution Monitor is a powerful tool, designed to deliver the fastest path to accurate dissolution analysis. Built with a world-class optical bench, it allows for simultaneous real-time data collection and analysis of up to 8 vessels through a user-friendly software interface. It's the detection core of the MicroDISS Profiler. 

DissoPRO™ is a secure, traceable software package that allows Pion’s fiber optic users to develop and run dissolution methods in a 21 CFR Part 11 compliant framework. It allows you to effortlessly save and transfer fiber-optic methods from your development lab to your QC/Compliant lab.

Overview

With 20 years of proven efficiency, Pion’s Rainbow® serves as the benchmark for in situ dissolution monitoring and is widely used throughout the industry. Researchers engaged in USP dissolution and those using more novel apparatus can utilize this powerful tool to improve throughput, reduce consumables, eliminate waste streams and provide more detailed profiles. The Rainbow® also eradicates clogging, leaking and the need for pump maintenance thanks to its ability to ‘pump the light, not the liquid’.

Applications

  • Small volume dissolution – tablets and powder
  • Nanoparticle dissolution
  • Intrinsic dissolution and rank order intrinsic dissolution
  • USP and EU dissolution
  • Biorelevant dissolution media
  • Excipient screening
  • Salt screening
  • Stability monitoring
  • Media pH change
  • Dynamic media change
  • Detect polymorphic changes
  • Supersaturation studies
  • Solubility – Aqueous and Non-Aqueous
  • Follow stability profiles
  • Track supersaturation effects
  • Determine equilibrium solubility
  • Biphasic Dissolution
  • Artificial stomach duodenum monitoring

Features

Robust

The Rainbow’s dip style probes and interchangeable reflectance tips are engineered from stainless steel, with a horizontal analysis path available through the J style dip probe.

Flexible

Variable path lengths of 1, 2, 5, 10 or 20 mm for maximum flexibility.

Cost-effective

Fast return on investment due to low maintenance cost, automated data collection, and enhanced capability

Fast

Up to 8 individual Photo Diode Array Spectrophotometers allows data collection of  UV/VIS spectra (200 – 720 nm) at 1nm resolution as often as every two seconds from all vessels simultaneously.

Versatile

Up to 8 data acquisition channels
