You need high quality laboratory bottles for safe storage in the lab.
But even the best bottles are unreliable without the right closure.
The tried-and-tested, comprehensive range of Duran laboratory bottles has long been established as the quality standard in the market with their distinctive blue caps.
New to the existing range of caps are tamper evident PP closures with the common ISO GL 45 screw thread.
The screw caps are made of PP (polypropylene) and the standard version is blue with a red ring.
Once they are opened for the first time, the caps can continue to be used on the bottle, whilst the detached 'tamper evidence' ring indicates that the contents have been accessed.
For secure storage of the bottle contents, they have a lip gasket and are autoclavable to 140C.
