The DURAN pressure plus+ GL 45 bottles offer a safer option for laboratory applications involving
vacuum or pressure. Standard glass laboratory bottles are not designed to safely withstand pressure differentials.
As a result of a modified geometry, the pressure plus+ bottles have a guaranteed pressureresistance,
and consequently offer optimal safety for both the user and contents. Three versions of the
pressure plus+ bottles are available; clear DURAN glass with or without a protect plastic safety coating,
and amber DURAN glass for protection against ultraviolet light degradation.

Recommended bottle to use with the DURAN DG cap systems. Specially designed to be pressure-resistant from -1 to +1.5 bar according to ISO 4796 and garentees certified safety compliant with EN 1595. GL 45 thread.
