Central Research Facility (CRF) — Integrating Sphere & Peltier Accessory Installed
The Central Research Facility (CRF) has installed a UV-VIS-NIR Spectrophotometer (Agilent Cary 5000). It includes an Integrating Sphere for diffuse reflectance of powders and a Peltier accessory for kinetics measurements of liquids from room temperature up to 80°C. The Colour Calculator software is available for determining colour coordinates.
