The VHP M10 Biodecontamination System utilizes Vaprox Sterilant (EPA Reg. No. 58779-4) as a means of achieving dry, low temperature sterilization within sealed enclosures such as isolators and glove boxes. The dry, gaseous process consists of four distinct phases: Dehumidification, Conditioning, Biodecontamination and Aeration. Aeration continues until hydrogen peroxide is reduced to an acceptable level.
