Plas-Labs desiccators are designed to protect, store, or assist in moving critical materials and prevent contamination. They are dust and moisture free enclosures which safeguard valuable research specimens or sensitive electronic components. Under positive N2 gas flow, they prevent moisture from penetrating the molecular structure of stored components. You may easily observe the status of your components without opening the door. Our amber units are very effective for protection from harmful U.V. rays for light sensitive components.
