Do you use Spectra S1/S2/M1 and 9+ breastpumps but feed your baby with Medela, Ameda, Dr. Brown or other narrow-neck bottles?

When you use the wide-mouth pump body of a breast pump(S1/S2/M1 and 9+ pumps), you can not use the standard caliber bottle confusion in the breast pump. For example, the Medela, Ameda, Dr. Brown and other standards caliber bottles.

That is why this bottle converter exist!

With this converter, you can simply use the standard diameter bottles stored in the above breast pump and do not need to re-pour the milk storage, which can be reduce the chance of contamination of breast milk and reduce your work.

Plus they are used by the food grade PP plastic production, BPA-Free, dishwasher safe, making it safe for your little one.


1, Screw the small inner ring of the converter onto a standard-sized bottle (e.g. Medela, Ameda or Dr. Brown) first.

2, Insert the outer ring of the converter assembly from adapter into an Spectra S1/S2/9  wide-mouth flange. Don’t insert it all the way in as it might not screw on easily.

3, Turn the bottle to allow the thread from the flange to take in the converter and the bottle.


Prior to first use and after each use, wash with hot water and mild detergent then rise clean. Sterilize by boiling in water for 5 minutes if needed.


1, Tighten up the bottle before using. 

2, Keep the bottle upright when you are pumping to avoid wasting the breast milk.
