An independent diagnostic laboratory specializing in Nutritional and Environmental analytical services has performed Contaminant Screens on our Latex, Rubber, Polypropylene, Polyethylene, and Polycarbonate products. The results have all been below thresholds due to the fact that these materials are non-digestible. Representative results of these analyses are available upon request. Based on the above findings, Bio-Serv conducts these analyses semi-annually. Additional contaminant screens can be performed at the customer’s expense. Contact a Customer Service Representative for more information.
