How to Pump Directly Into Mason Jars

“Mason Bottle makes feeding healthy, affordable, and easy, but can you pump directly into a Mason Bottle?” The answer... YES

At Mason Bottle, we are constantly working to find ways to make life simpler and safer for your family. In fact, what Mason Bottle families tell us they love most about using mason jars is that you are able to store, heat, and feed breastmilk all from the same jar!

Not only does it simplify the feeding process but still allows you to promote a healthy economy, environment, and most importantly a healthy life for your little one!

You save a lot of time, money, breastmilk, and energy buy simply omitting the need to transfer from pump bottle to jar. While transferring from a plastic pumping bottle to a mason jar still beats the heck out of those single use plastic storage bag, being able to pump directly into the mason jar is what is ideal. 

We searched long and hard for a solution to one of our number one received questions... and now dreams have become reality with the Nanobebe adapter!

The adapter fits all standard pumps to include Spectra, Medela, Lanisoh and Ameda and attaches flawlessly to regular mouth mason jars with nothing but either a metal or plastic ring. Since our Storage jars have a single piece lid, if you are using them, make sure you grab a pack of rings as well if you don't have any metal ones at home.

The Nanobebe adapter is sold with 1 adapter per box so if you double pump, you would need to purchase 2 boxes. They are sold for right here on our website!

There is another adapter, the Maymom, however it only fits Spectra S1 and S2 models of pumps. It can be found on Amazon as well and is around $12 for 4.

With these options available, you can say goodbye to those pesky bags, tedious transfers and never have to cry over spilled milk again.

    I’m planning to pump directly into my mason jars and wondering what bras might work to support the weight of the glass jars for handfree pumping?

    Is there a way to adapt a mason bottle to a Lansinoh breast pump???

    The Medela adapter for Nanobébé bottles works with regular mouth mason jars! I just pumped twice today using them!

    Wow, have been trying to find an adapter that would work. This works great with my Spectra S2 pump! Thank you so much!! :)

    This makes me so happy! I am going back to work and pumping into plastic bottles felt like it went against the idea of using glass bottles. I am super excited to give this a try. Thank you posting this.
