  • Supports anaerobic culture conditions inside the bottle
  • Allows multiple punctures for easy syringe access to bottle contents
  • Elastic material ensures effective sealing and reliable self-sealing after needle piercing
  • Material is virtually free of organics that might leach into the incubation medium
  • Stopper shape and material properties optimised to fit DURAN™ GL 25 and GL 45 bottles
  • Wide usable temperature range: -50 to +121°C
