Material: DURAN ® glass (borosilicate glass 3.3), screw caps made of PP, blue. Autoclavable: yes. Ideal for storage and dispensing of mobile phases and solvents suitable for high performance liquid chromatography (HPLC). Practical - side neck allows filling of bottles without removing the main connection. The Hydra multi-neck bottle can take up to five HPLC caps, which increases safety when working and reduces the risk of cross-contamination and air intake Safe - closed bottles reduce the risk of escape and spillage of volatile organic compounds (VOC) Compatible - GL 45 thread appropriate for standard HPLC-connection caps Produced from the material of choice for HPLC solvent bottles: borosilicate glass 3.3 has a very low profile of extractable inorganic ions DURAN ® is a borosilicate glass type 3.3 according to the specification in international standard ISO 3585, which is classified according to ASTM-E438-1992 as "borosilicate glass type I, class A with low expansion" With retrace code and certificate for tracing the production batch Long-lasting scaling through permanently fired-on print image Autoclavable at 121 °C or 134 °C Applications: Reservoirs for mobile phases for HPLC HPLC flushing bottle Supply of reagents to systems and analysers that work with liquids Multi-neck HPLC bottle DURAN ® GL 45 Round with a GL 45 side neck Delivery incl. screw caps made of PP.
