The Pure Expressions RTLBP1000 is a single electric breast pump designed for portability and efficient expression. Engineered to mimic an infant's natural nursing pattern, this pump features Two-Phase Expression technology , allowing users to transition from a rapid Initiation Mode (to encourage milk flow) to a rhythmic Expression Mode (to maximize milk collection). With 9 adjustable suction strengths and a quiet motor, it provides a discreet and personalized experience for daily use. Hygiene is prioritized with a Closed-Loop Anti-Backflow System , which provides a physical barrier that prevents breast milk from entering the tubing or motor, significantly reducing cleaning time and helping to maintain a clean pumping environment. The lightweight unit features a backlit LCD for real-time tracking of settings and session duration, and operates via the included AC adapter or a portable battery source for reliable performance at home or during travel. Key Features Two-Phase Expression: Imitates natural nursing with separate Initiation and Expression modes for optimized milk flow. 9 Suction Levels: Adjustable digital controls allow for a highly customized and comfortable experience. Closed-Loop Technology: Integrated diaphragm prevents backflow, ensuring milk stays in the bottle and away from the pump motor. Discreet & Quiet: Engineered for low-noise operation, suitable for night-time pumping or use in professional environments. BPA & Latex-Free: All components that contact breast milk are constructed from BPA-free, latex-free materials. Digital LCD Interface: Clear display features a 30-minute timer and a memory function that saves your last pumping session settings.
