• Stopper shape, and material properties optimized to fit GL45 bottles with sizes from 100mL to 20L.   
• Low permeability to air, gases and moisture.
• Manufactured from a high purity bromobutyl rubber elastomer.
• Conforms to EP 3.2.9 Type I closure for chemical and penetration tests.
• Material is virtually free of organics that might leach into the incubation medium.
• Elastic material for effective sealing and reliable self-sealing after needle piercing.
• Upper surface features seven numbered hemispherical impressions for needle-piercing.
• Wide usable temperature range: -50 to +121 °C.
• Suitable for autoclaving / steam sterilizing at 121 °C for 20 minutes.

Stopper provides a gas tight seal for all GL45 laboratory bottles. Bromobutyl rubber is essentially impermeable to most gases and provides a controlled environment inside the glass bottle for oxygen sensitive materials. Useful for maintaining anaerobic culture conditions. Butyl rubber allows for multiple punctures providing easy access to the contents with a syringe. Suitable for autoclaving/steam sterilizing at 121°C for 20 minutes. Bottle and cap must be purchased separately.

Applications
• Culture of anaerobic microorganisms (pressure resistant bottles recommended).
• Storage of anaerobic culture media (amber glass bottles recommended).
• Aerobic methane oxidation (MOx) research.
• Storage of oxygen sensitive materials.
• Applications requiring gas purging or sample transfer via a syringe.
