Product Overview
DURAN® bromobutyl rubber closures provide a gas tight seal for GL 25 or GL 45 glass laboratory bottles. As a material Bromobutyl rubber is essentially impermeable to most gases, and the stopper provides a controlled environment inside the glass bottle for oxygen sensitive materials. Useful for maintaining anaerobic culture conditions. Bromobutyl rubber allows for multiple punctures providing easy access to the contents with a syringe. A Type III Packaging Material DMF (#35811) for these products has been filed with the FDA.
