Bottle-top dispensers
The DURAN Group dispenser can be screwed directly onto the bottle thread. The thread of the DURAN Group dispenser is optimally matched to the GL 45 thread of the DURAN® laboratory glass bottle.

This ensures optimum sealing and reduces any loss of media. Additionally, safe storage of the contents and protection against escaping vapour is ensured.
