Do these bottles fit Spectra flanges directly?
Yes. These wide neck bottles attach straight to Spectra and Aaya wide-neck flanges, no adapter needed.
Are bottle nipples included?
No, these bottles are designed for pumping and storage, not feeding, so nipples aren't included. They're compatible with most standard wide-neck nipples if you'd like to use them for feeding directly.
How much milk does each bottle hold?
Each bottle holds 180mL, slightly more than the standard 160mL size, giving you a little extra room during longer pumping sessions.
How long can I store breast milk in these bottles?
Freshly pumped milk keeps up to 4 hours at room temperature, up to 4 days in the refrigerator, and up to 6 to 12 months in the freezer. Thawed milk should be used within 24 hours in the fridge and should never be refrozen. See our full storage guide above for details.
