Riboflavin is, a type of vitamin B found in food, is selected for vessel coverage studies due to its fluorescent properties under ultraviolet light and Riboflavin coverage test is use for determine the coverage of spray ball which is use for Clean-in-place (CIP) systems are used in the pharmaceutical industry to clean one or more vessels in the manufacturing process. Spray Balls are internally installed in vessels to ensure the CIP system can properly clean all areas of the tank. During the cleaning cycle, Spray Balls disperse cleaning solution and provide physical action to remove residues inside equipment. Spray Balls must deliver adequate tank coverage for a complete clean.
