Brown's wide neck, Avent & MAM.Ģ) Medela valves (yellow valves and membranes) are compatible with Spectra pumps and are preferred by some users. Wide-neck bottles that should be compatible include Dr. Ultimately, options will likely become limited to just the 2-piece setup in the future.ġ) Bottles of different brands can fit the Spectra flange. Opinions are mixed - some prefer the duckbills while others prefer the 2-piece setup. UPDATE: Spectra is replacing their duckbill valves with a 2 piece system similar to the Medela valve/membrane setup. When a white valve needs replacing you will notice a decrease/loss of suction on that side or that valve is sputtering & splashing up milk during the vacuum part of the cycle." When sterilizing them, I try to be sure they aren't squashed by other pump parts during the process. I clean my white valves by putting them in a bottle with warm water, letting them soak & then gently swirling them around. If these white valves develop a tear or stretch out, the suction seal will fail. "Be very careful when handling & washing the white valves! They are very delicate & can tear or stretch easily. An excerpt from the Ameda Pump Info Post: Precautions with Spectra valves are similar to those needed with Ameda valves. Here is a picture with an Ameda valve (on left) & a Spectra valve (on right). You can choose to regularly replace these or just when you notice one isn't functioning properly anymore. These may need to be replaced periodically due to wear & tear. The duck billed valves are similar (but not identical) to the white valves on Ameda & Hygeia pumps. Pay attention to the orientation of the components when assembling! A 21 mm size can be obtained through use of an insert.)Ĭlosed system is achieved by use of 2 separate 3 piece "backflow protectors" which sit between the flange and tubing. The S1 also has an internal rechargeable lithium battery.Ĥ) Single bottle holder, handle & nightlight built into motor housingĦ) Built-in timer (30 minutes with automatic shut off - will return to the settings used just prior to shut-off when turned back on)ħ) Quiet motor (~45 dB, a refrigerator is ~50 dB)įully sterilizable collection kit - comes standard with 28 mm single piece flanges (Available in multiple sizes for separate purchase including 24 mm, and 32 mm. Suction levels: up to 300 mmHg (12 levels unless in letdown mode)Ģ) Electric via wall outlet. These pumps are considered, by the manufacturer, to be adequate to both establish & maintain a milk supply when nursing is not feasible or desired)ġ) Dual button digital display for independent cycle speed & suction strength.Ĭycle speed: 38-54 cycles/minute (5 levels) & also has 70 cycle/min "letdown" mode with adjustable suction strength (up to level 5) (The term "Hospital Grade" is applied by the Spectra.
