Noxilizer - Ultra-Low Temperature Nitrogen Dioxide Sterilization And Decontamination Technology
Noxilizer has developed an ultra-low temperature nitrogen dioxide sterilization and decontamination technology that addresses many of the challenges associated with traditional methods. NO2 is effective against a wide range of microorganisms. The primary mechanism of lethality is the degradation of DNA. Late outgrowth studies have shown no repair mechanisms for the DNA degradation.
Nitrogen dioxide is a true gas. The boiling point of NO2 is relatively low, at 21°C, and Noxilizer employs sterilant concentrations that are well below the vapor pressure of NO2. The NO2 gas will not condense on devices. It is a surface sterilant. Therefore, NO2 gas can sterilize prefilled syringes, while maintaining drug integrity, and medical devices with complex geometries.
Only NO2 sterilization offers all the following benefits
Nitrogen dioxide gas sterilization is ideal for sensitive biotech products and improves supply chain efficiency:
- Ultra-low temperature sterilization (10°C – 30°C) — maintains drug integrity
- Minimal vacuum option — prevents stopper movement
- Surface sterilization process — does not leach through the stopper
- Short cycle times (2-6 hours) including aeration
- Safe and easy to bring in house — reduces manufacturing time and cost
Aerates Rapidly – Minutes vs. Days
Low boiling point, coupled with the low NO2 sterilant concentrations, translates into rapid aeration of the sterilization chamber and exposed products.
NO2 does not permeate materials to the same degree as other methods, greatly reducing the overall cycle time of the sterilization process and eliminating the lengthy post-sterilization aeration. This benefit applies to terminal sterilization using a batch process or high level decontamination in isolators.
Decontamination Cycle Profile
NO2: Half the total process time of H2O2
Low Residue Levels – Non-carcinogenic, non-cytotoxic and non-teratogenic
The rapid aeration process results in fewer residues on product and packaging. Noxilizer’s sterilant residues are non-carcinogenic, non-cytotoxic and non-teratogenic. Sterilized packages may be handled immediately after the cycle.
Compatible with Common Packaging
Noxilizer’s sterilization process is compatible with commonly used sterile barrier packaging. This includes: non-woven polypropylene, Tyvek® pouches, Tyvek®-Mylar® pouches and plastic tubs with Tyvek® lids. Noxilizer’s process is not compatible with cellulosic materials such as paper and cardboard.
