The DURAN® HPLC bottle consists of a complete system. It is made up of the special DURAN® pressure plus laboratory bottle and a screw cap with four ports. The four ports make it possible to serve three stations at the same time from one container. At the same time, the fourth port can be used for sterile pressure equalization. The system is suitable for tube diameters of 1.6 mm (1/16 inch) and 3.2 mm (1/8 inch). Ports that are not in use can be closed with a silicone seal.
The DURAN® pressure plus bottle is pressure-resistant thanks to its special geometry. Its pressure resistance is TÜV-GS certified. The bottle has a retrace code for downloading a certificate of conformity from the internet. This contains not only the batch and manufacturing data but also additional information about standards and USP/FDA conformity.
