VHP Advantages

Press start

�Easy to use

VHP Advantages VHP Advantages

� Short cycle time compared to EO

� Simple installation

� Shelf-life with wrapped devices

� Non-toxic, environmentally friendly

(byproducts are water vapor and O2)

� Conditioning phase – minimizes aborts due to

moisture

� H2O2 cup sealed and vented – easy to insert,

automated
