PureAtom

PureAtom LLC develops reliable, low-cost containers for storing and shipping oxygen-sensitive materials. Founded in 2024 by nuclear materials scientists and engineers, the company focuses on solutions for materials science research in regular and extreme environments. Its products are designed to help researchers preserve specimens, reduce repeated sample preparation, and make long-term storage safer and more efficient.

The range includes disposable and reusable room-temperature argon air-free containers, as well as replacement cord gaskets. The containers use a self-sealing design and argon purging; PureAtom says a 10-minute purge at less than 2 psi can support storage for months. They are intended for applications involving battery, nuclear, semiconductor, and life-science materials.

PureAtom reports performance validation using transmission electron microscopy and electron energy loss spectroscopy on uranium-molybdenum specimens. In a seven-day comparison, its container showed no detectable oxygen peak, while a regular container did. The company also describes independent air-tight testing. Results may vary by material, and the site states that no warranty is provided.
