€¢ Applications requiring gas purging or sample transfer via a syringe
DURAN bromobutyl rubber closure provide a gas tight seal for all GL 45 laboratory bottles.
Bromobutyl rubber is essentially impermeable to most gasses, 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.
€¢ Stopper shape, and material properties optimised to fit DURAN GL 45 bottles with sizes from 100 to 20,000 ml.
€¢ 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 sterilising at 121 °C for 20 minutes
€¢ Use with the DURAN GL 45 open topped / aperture screw cap for extra security
