Core Functions and Working Principles
1. Pressure Balancing (Breathing/Breathing):
During storage and transportation, changes in temperature and air pressure (such as altitude changes during air transport) can create a pressure difference between the inside and outside of a container, or the bottle may contain gas-generating liquids or solids.
Breathing gaskets utilize this pressure difference to allow air to slowly pass through their micropores, balancing the pressure inside and outside the container and preventing the container from bulging due to positive pressure or collapsing and leaking due to negative pressure.
2. Maintaining a Sterile Barrier:
The micropores in the breathable membrane are extremely small and made of a hydrophobic material.
This means that liquids and aqueous substances cannot pass through, and airborne microorganisms such as bacteria and mold cannot penetrate. This ensures the sterility of the container.
3. Allowing Gas Exchange:
In some cell culture or biological experiments, the exchange of carbon dioxide and oxygen is necessary to maintain cell activity while preventing contamination. Breathing gaskets can meet this need.
4. Provides Sealing and Protection:
· The aluminum foil layer provides an excellent barrier to light, oxygen, and moisture, protecting the contents from oxidation and moisture.
