Potential Uses:

1. Chemical Handling: PTFE stoppers are commonly used in laboratories for sealing containers holding various chemicals. Their chemical inertness makes them suitable for applications involving corrosive or reactive substances.
2. High-Temperature Applications: PTFE has a high melting point and is resistant to high temperatures. PTFE stoppers are used in applications where elevated temperatures are involved.
3. Biotechnology and Pharmaceuticals: PTFE stoppers may be used in the biotechnology and pharmaceutical industries for sealing containers during the handling and storage of sensitive substances.
4. Gas Handling: PTFE stoppers are suitable for applications involving gases due to their low permeability and resistance to gas diffusion.
5. Laboratory Glassware Sealing: PTFE stoppers can be used to seal openings in laboratory glassware, providing a secure closure for flasks, bottles, or tubes.
6. Quality Control: Laboratories adhering to ASTM standards may use PTFE stoppers in quality control processes to ensure that laboratory materials and containers meet specific criteria.
7. Electrochemical Applications: PTFE’s chemical resistance makes it suitable for applications involving electrochemical processes.
8. Nonstick Properties: PTFE’s nonstick properties make it useful in applications where adherence of substances to the stopper surface needs to be minimized.
