The Spectra® SG Synergy Gold double adjustable electric breast pump offers the most advanced and up-to-date technology in the industry. The SG is the first pump of its kind that allows moms to adjust each side independently! Like all Spectra pumps, the SG is a true closed system, creating a hygienic barrier between outside contaminants and mother’s milk. This advanced technology promotes more productive pumping sessions that can save time with comfort and ease. The LED lamp shines a mild indirect light for breastfeeding in dark rooms and as a sleep lamp.
