The Spectra Single Breast Shield is strategically constructed to provide efficient breast pumping sessions with maximum comfort. To obtain the proper suction during pumping, the Spectra Single Breast Shield funnel centers over your nipple to create a seal around the areola. The Spectra Single Breast Shield creates a vacuum to draw the nipple inside the funnel gently, to extract milk. Manufactured without BPA, the Spectra Single Breast Shield is easy to clean and safe for moms and babies. If you?re double pumping you?ll need two Spectra Single Breast Shields. The Single Breast Shield can be used as a replacement part or for moms needing an extra breast shield handy at home or in the office.
The Spectra Duckbill Valve is designed to increase suction and provide better output during breast pumping sessions while preventing backflow contamination. Each duckbill valve is one-piece making it easier to clean and lasts longer. Spectra Duckbill Valves are made of silicone and quality tested to ensure a sturdy grip on small, medium, large, or x-large breast shields and flanges. All Spectra Breast Pump parts that come in contact with Breast Milk are BPA free.
