Potential Uses:
- Laboratory Glassware Sealing: Pennyhead solid glass stoppers are often used to seal laboratory glassware such as flasks, test tubes, and bottles, providing a secure closure.
- Chemical Reactions: In chemical reactions, solid glass stoppers are used to seal reaction vessels, preventing the escape of gases or vapors and allowing for controlled reactions.
- Storage of Samples: In research and analytical laboratories, glass stoppers are used to seal containers holding samples to prevent contamination or evaporation.
- General Laboratory Practices: Pennyhead stoppers are easy to handle, making them convenient for quick sealing and unsealing of laboratory glassware during various procedures.
- Quality Control: In laboratories adhering to ASTM standards, these stoppers may be used in quality control processes to ensure that laboratory glassware meets specific criteria.
