Tissue culture sealing film Usually consists of a multi-layer structure, each layer has different functions and properties. The following is a typical material structure of a common tissue culture sealing film:
1. Base Base layer: The base layer is the main supporting layer of the sealing film and is usually made of polymer materials such as polypropylene or polyester. This layer provides the strength and stability of the parafilm.
2. Adhesive layer (optional): Some tissue culture sealing films may have an adhesive layer. This layer is responsible for generating adhesion to the surface of the petri dish and ensuring a tight fit of the sealing film.
3. Gas permeable layer: The gas permeable layer is a key part of the sealing film. It determines the amount of gases such as oxygen, carbon dioxide and water vapor in the sealing film. permeability. This layer is often composed of a polymer film or microporous membrane that balances the gas exchange needs of the cell culture environment.
4. Anti-pollution layer (optional): In order to reduce the risk of contamination from external microorganisms, the sealing film may have an anti-pollution layer added. This layer can prevent the penetration of bacteria and maintain the culture environment.
Please note that the specific structure of tissue culture sealing film may vary depending on the brand and model. Therefore, when selecting and using Tissue culture sealing film, it is recommended to refer to the product description and usage guide provided by the manufacturer to ensure a correct understanding of its material structure and performance characteristics.
