Medela has developed the Symphony One-Day Pump Set especially for use with the Symphony 2-Phase Expression Breastpump. The set contains all the specific pump parts that are needed to fulfill strict, hygiene standards such as membrane cap and protective membrane. The result: a complete system for the number one breastpump. In addition, mothers receive a disposable 150 ml breastmilk bottle for collecting, storing and feeding breastmilk.
