The Nanostopper Bag Adapter converts any airtight food bag into a vacuum bag, suitable for portioning, (freezer) storage, marinating and sous vide cooking. No more need for special, expensive valve bags thanks to Nanostopper.
Place the adapter with a Nanostopper® inside the bag and snap on the cap on the outside. The bag now has a valve to extract air from the bag!
Use the converted vacuum bags to marinate quickly and effectively, to portion food, preventing freezer burn and for sous vide cooking.
The Nanostopper® with bag adapters even work on reusable silicone zip bags!
