VYCOR® porous glass is mechanically hard and strong, nondusting, nonflaking, and
chemically inert. These properties permit it to be employed as a noncontaminating getter -
it rapidly absorbs water and organic contaminants. This porous glass is presently being used
in transistors, microminiature relays and other small devices. It has practical application in
any sealed device that requires freedom from foreign contaminants.
