The Spectra S9 Hospital Grade Double Electric Breast Pump with impressive innovative features to fully support your breastfeeding journey. Ultra quiet and comfortable. Spectra breast pumps don't suck as much as they do suckle which provides a more natural breast pumping experience. Spectra pumps include hygienic backflow protection to prevent milk traveling down the tubing towards the pump and presenting a hygiene risk for mold, transmission of viruses and potentially impairing motor function. All components that come in touch with milk are BPA-free. Features extreme portability with inbuilt rechargeable battery, closed system for hygiene, two phase system-let-down(massage) and expression modes, adjustable suction/cycle in one touch button and one year warranty. Lightweight, less than 1 pound! LCD Lit Screen and Timer. Bonus Bundle includes CaraCups and standard flanges 24mm for your convenience.Lactation Consultant's Note: The Spectra 9 Plus Breast Pump is perfect for times you need extra portability, but wearable pumps are battery contingent and should not be the only pump you use for your milk supply. For every day use, we recommend the Synergy Gold by Spectra.
