Plastic and rubber laboratory apparatus contains materials that are extractable with water, aqueous solutions, and nonaqueous solvents. These extractable substances fluoresce under ultraviolet light and were found as contaminants in nutrient solution used for growing excised lemon fruit tissue in vitro. The source of these fluorescent contaminants has been removed by using all-glass laboratory equipment.
