Easy Freeze for optimum storage and freezing of breast milk. Disposable product. Direct pumping from the pump set or from the Amaryll manual breastpump into the Easy Freeze bags is possible. The integrated heat indicator indicates when the milk is warm. A hygiene chamber system protects the milk from contamination. High-quality, FDA-tested double coating protects against foreign smells. Scaling up to 180ml. Sealable due to the handy zip closure. Filled bag stands on its own. The heat indicator remains gray even when it reaches a higher temperature. If it falls below approx. 32 degrees it turns blue again. Check the temperature of the breast milk before administration. Breast milk may only be administered when lukewarm (approx. 37 degrees) otherwise there is a risk of burning. Do not heat breast milk in the microwave. Do not freeze thawed breast milk.
