The silicone membrane pot integrated into the Pumpset is at the heart of our "Vacuum Seal" Technology. This technology ensures that there is a total barrier between the breast milk and any pathogenic agents. "Vacuum Seal" guarantees protection of the breast, breast milk and the pump against contamination. Components such as the silicone tubing do not have to be boiled/sterilised before use. Mothers will also not have milk in the tubing or in the breastpump.
