Why Pump Directly into Ceres Chill?
Pumping directly into your Ceres Chill eliminates the need for extra bottles and transfer steps. This is especially beneficial for working moms or those pumping on the go. By pumping directly, you keep your milk cold from the moment it leaves your breast, preserving its freshness and quality.
The Ceres Chill is designed to keep milk at a safe temperature for up to 20 hours, making it perfect for long workdays or travel. When you pump directly into it, you avoid the risk of warming milk during transfer and ensure that every drop is stored safely.
- Save time by skipping bottle transfers
- Reduce the risk of spills and contamination
- Keep milk cold from the first drop
What You Need: Pump Converters
To connect your Spectra pump to your Ceres Chill, you'll need a pump converter. Ceres Chill offers Pump Converters that are compatible with Spectra pumps. These converters fit securely onto the Ceres Chill lid, allowing you to attach your pump directly.
The Pump Converters are easy to use and come with clear instructions. They are designed to fit both the OG+ and Demigoddess Chillers, so you can use them with your preferred model. Whether you have the CeresBFF OG+ Chiller/Warmer or the Demigoddess Mini Chiller/Warmer, the converter will work seamlessly.

- Ensure you have the correct converter for your pump model
- Check compatibility with your Ceres Chill model

Step-by-Step: Pumping into Ceres Chill with Spectra
First, assemble your Ceres Chill with the pump converter. Remove the lid and attach the converter to the opening. Make sure it's snug and secure. Then, connect your Spectra pump tubing to the converter. Your pump is now ready to express milk directly into the Chiller.
Start pumping as you normally would. The milk will flow directly into the Chiller, which keeps it cold. Once you're done, disconnect the pump and replace the lid. Your milk is now stored safely at the perfect temperature.
- Attach the converter to the Chiller lid securely
- Connect your Spectra tubing to the converter
- Pump as usual – milk flows directly into the Chiller
- After pumping, replace the lid to maintain temperature
Tips for a Smooth Experience
To ensure a smooth experience, make sure your Ceres Chill is pre-chilled before you start pumping. This helps maintain the cold temperature from the first drop. Also, clean and sterilize the converter regularly to maintain hygiene.
If you're using the OG+ Portable Chiller/Warmer - 28oz, you can pump directly into it just like the standard models. The larger capacity is great for longer pumping sessions. Additionally, consider using the Pumping Accessory Pouch to keep your pump parts organized and within reach.
