The antioxidant DNA preservation system is sealed in a dry, oxygen-free, antioxidant environment and can be preserved permanently at room temperature, its natural environment.
1. Place the product containing the body part containing DNA into the vacuum chamber.
2. Create a vacuum environment by removing internal oxygen by exhausting the internal air with a vacuum pump.
3. Nitrogen is colorless, odorless, and inert, and replaces the exhausted air to prevent DNA contamination and oxidation. For long-term storage of DNA, inert gas (nitrogen) is injected into the chamber instead of air. This eliminates the pressure difference between the inside and outside of the product.
4. In a nitrogen-filled environment, the product containing the body part containing the DNA is welded and sealed.
