All Medela products that come into direct contact with breastmilk are, and always have been, made from BPA-free plastic. As an industry leader in breastpumping and breastfeeding, Medela is committed to always doing what is best for mothers and babies. Breastmilk is best for the baby and the baby's natural sucking rhythm is best for the mother. In intensive pioneer work, Medela has converted the baby's intuitive knowledge into technological know-how. The result is 2-Phase Expression--the standard for unsurpassed naturalness, comfort and efficiency in breastpumps.
