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.Key Features

• 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)

Phantoms
Blue Water Phantom
Photon Beam QA
Fast, easy-to-setup alternative to water phantoms for routine checks of linac photon beams. A New Standard in Water-Equivalency
Water equivalent material within 1.0% for photons, and is free of contaminants and air. Slabs from this unique material are exceptionally strong and will not stick together when stacked or stored. Not affected by changes in temperature or humidity and can be used for electrons.

 Unique Chamber Slab Design
In slabs that are at least 2 cm thick, cavities are available to accommodate parallel plate ion chambers or thimble type ion chambers. Instead of having multiple slabs for each thimble type ion chamber, a single ion chamber slab is used with interchangeable ion chamber plugs.
