About this item
DURAN® Bromobutyl Rubber closures provide a gas tight seal for all GL45 laboratory bottles with sizes from 100 to 20000 ml. 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.
- Low permeability to air, gases and moisture
- Material is virtually free of organics
- 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
They are used in anaerobic culture of microorganisms, storage of anaerobic culture media, aerobic methane oxidation, storage of oxygen sensitive materials and applications requiring gas purging or sample transfer via a syringe.
These stoppers are suitable for autoclaving or steam sterilizing at 121 °C for 20 minutes.
Used with aperture screw cap for extra security.
