Quantity 3: 5cm Thick (Item # 605-350) 
The kit also includes a watertight wheeled case

Custom Cavities Available
Cavities are available in slabs at least 2 cm thick to accommodate most Farmer-type or parallel plate ionization chambers. Optional scribe lines are available for laser alignment.

Tested and Calibrated
Virtual Water is a true water-equivalent material. Slabs from this unique material are exceptionally strong and will not stick together when stacked or stored. Virtual Water is not affected by changes in humidity or temperature and does not exhibit charge storage effects, a problem common in other water-equivalent materials. Each production run of Virtual Water is tested at an independent calibration laboratory and certified to be within 0.5% of water at photon and electron energies.

Setting the standard in water-equivalency
Virtual Water slabs are made from water-equivalent material, and are developed to be free of contaminants and air. Many standard sizes and thicknesses are available and custom phantoms are available upon request.
