  Light Stability Testing of Liquids Using SUNTEST

  November 15, 2024 | Dr. Oliver D Rahaeuser

  Applications

  Over the past 20 years, various test methods have been developed for testing liquid using Atlas SUNTEST instruments. Preparations inside vials, petri dishes, or small quartz containers are typical applications. If a realistic full-spectrum exposure with controlled temperature is required, SUNTEST CPS+ or XLS+ are preferred over simpler laboratory UV-radiation sources.

  Fast Color Fastness Testing of Packaging

  November 15, 2023 | Dr. Oliver D Rahaeuser

  Applications

  Without a doubt, attractive packaging sells, because we tend to buy products with our eyes. Packaging is a brand vehicle and strongly contributes to the value of a product. Therefore, the printing must withstand the impact of light and heat. In other words, the product moves faster before color shifts or color fading of packaging occurs.
