Virtual Water^® Phantom True Water-Equivalent Material

Each batch of Virtual Water is tested at an independent calibration lab and verified to be within 0.5% of water at photon energies. It's not affected by changes in humidity or temperature and does not exhibit charge storage effects, a problem common in other water-equivalent materials.

Slabs are made from water-equivalent material, and are developed to be free of contaminants and air. Slabs from this unique material are exceptionally strong and will not stick together when stacked or stored.
