| The Sevalco plant at Bristol is one of the largest carbon black plants of Columbian Chemicals. The Sevalco plant uses Leica equipment, including a Leica MZ12.5, to analyse carbon black dispersion in plastics. Dr. Silke Kite, Industrial Application Specialist in the Industrial Applications Laboratory, explained: "Our laboratory carries out both research and consultancy work on the purity and applications of carbon black. We needed to develop a test to analyse its dispersion in plastics as the test used for rubber was not suitable. With rubber, the freshly cut surface can be analysed with a diamond showing the carbon black trapped inside. The same test cannot be applied to plastic because it is too stiff." Silke Kite continued: "We purchased a Leica equipment that contains a Leica MZ12.5 stereomicroscope and a Leica DC digital camera. The new equipment has helped us a great deal and we can now do so much more than before.” Image Courtesy Sevalco plant, Bristol, Columbian Chemicals
