VHP Chemical Indicators provide visual assurance that
exposure to hydrogen peroxide vapor has taken place.
The
Chemdi VHP Chemical Indicators consist of a short,
laminated paper strip printed on one end with a yellow
indicator ink that is responsive to hydrogen peroxide
vapor. Once exposed for an appropriate period of time
to hydrogen peroxide vapor, the yellow indicator ink
changes to a violet/grey color.
|
|
| The
entire strip, except one side of the color indicator
additional section, is laminated to prevent hydrogen
peroxide vapor from being absorbed into the paper,
and each strip is slightly curled so that the hydrogen
peroxide vapor flow can easily contact the non-laminated
color indicator section. |
