Overview

Wafer devices are a specialized type of permeation tube where only a small area of the tube is permeable, creating a window—or wafer—that allows very low permeation rates. Like perm tubes, wafer devices are small, inert capsules containing a pure chemical compound, but permeation occurs only through the polymeric wafer; thus, the permeation rate can be controlled by varying the wafer material, thickness, and diameter of the permeation opening.

Gases with a high vapor pressure at normal permeation temperatures sometimes cannot be contained in a typical permeation tube device. Wafer devices are ideal for applications with these gases. VICI Metronics wafer devices are available in different styles for use in calibrators made by various manufacturers.
