Tested and Calibrated
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.
Flatness
0.2 mm (0.008 in)
Density
1.04 g/cm3
Batch Consistency
±0.02% (measured)
Thicknesses Tolerance
±0.15 mm (0.006 in)
Length & Width Tolerance
±0.5 mm (0.02 in)
The Standard in Water-Equivalency
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.
