More about our materials & testing

Silicone is a man made material derived from silicon (a natural element found in sand) combined with oxygen and small amounts of carbon and hydrogen. It has a different structure than traditional plastics, which makes it more stable and heat resistant, and widely used in baby and food products.

Yes. Silicone is a stable material that remains durable across refrigeration, freezing, thawing, and warming temperatures. When used as intended, it does not leach chemicals into stored milk and is designed to help preserve the quality of breast milk throughout the storage process.

Yes. MilkHaven is fully reusable and designed for long term use, often across an entire breastfeeding journey, multiple children, and beyond milk storage.

Yes. MilkHaven is designed for refrigerator and freezer storage and remains durable and flexible at cold temperatures. Frozen milk can be thawed in the refrigerator or warmed using standard breastmilk warming methods. The silicone material is designed to withstand repeated freezing, thawing, washing, and everyday use.

Yes. MilkHaven can be used for freshly expressed, chilled, or frozen breast milk. Always follow current milk storage guidelines for timing and handling.

Each MilkHaven tube holds 2 ounces of breast milk, with 1 ounce and 2 ounce markings clearly labeled for easy portioning. Each MilkHaven box includes 20 tubes, providing a total storage capacity of 40 ounces per box in a modular, stackable format. Additional capacity is achieved by stacking multiple MilkHaven boxes as needed.

For everyday use, we recommend hand washing with warm water and non fragranced dish soap using the included bottle brush or soft brush. Rinse thoroughly and allow to air dry. MilkHaven is dishwasher safe, though frequent dishwasher use may shorten the lifespan of any silicone product.

Yes. MilkHaven can be briefly boiled or steam sterilized. Avoid harsh chemical sterilants or scented cleaning products.

Yes. MilkHaven’s silicone tubes can be labeled directly using an oil based paint pen, making it easy to track dates and feeding information. The included paint pen is freezer friendly, resists smudging from condensation, and washes off easily with soap and water when you’re ready to reuse the tube. A tested paint pen is included with every MilkHaven kit.
