Vaporized Hydrogen Peroxide (VHP) is a powerful chemical used to sterilize surfaces and
equipment in the cleanroom, specifically in the medical equipment and pharmaceutical
industries. It can cause deterioration and breakdown of equipment. Due to the nature of the
industries in which it is used, VHP is often used to sterilize equipment while the cleanroom
is in use. Thus, tools used in a cleanroom with VHP must be uniquely designed to withstand
exposure. Lighthouse’s Apex particle counters have been tested against VHP and show no
significant or out of the norm wear when exposed to VHP.
