Spectra Dual S (Synergy Gold) Dual Powered Electric Breast Pump

The Synergy Gold 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 with dual controls that allow for independent settings on each breast! Like all Spectra pumps, the SG is a true closed system, creating a hygienic barrier between outside contaminates 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.

Choosing the right size breast shield/flange

Using the wrong sized flange results in a painful and uncomfortable pumping experience and can make your very expensive pump produce as much milk as if you were using an $80 no-brand pump.

Breast shield sizing is more of an art than a science and depends on the diameter of your nipples (both before and after pumping) and the elasticity of your areola. The easiest and most effective way to get the right size flange is to have a Lactation Consultant watch while you pump, trying various sizes (I love Alona and she does home visits!).

The first step is to measure the diameter of your nipples when they're relaxed (not when they're contracted and hard), then buy N+2-to-3mm and N+4-to-5mm shields. Typically, your nipples won't both be the same size.

For example, if your left nipple measures 20mm in diameter, try the 22mm or 23mm shield and the 24mm or 25mm shield (for each pump brand, not all sizes will be available - eg. we don't have 25mm shields for Medela, but we do have 25mm shields for Spectra). If your right nipple measures 23mm in diameter, try a 25/26mm shield and a 27/28mm shield. If there's overlap in the shields you need to try for each breast, such as in this example, that's great. The mother in this example would only need to buy three shields: 22mm (to try for left breast), 25mm (to try for both breasts), 28mm (to try for right breast).

Once you've worked out which size fits your breast best, you can buy extras as needed. If this does your head in, contact us, tell us your nipple diameters and pump brand and we'll help you cart the correct shields.
