Range of application: for accurate dispensing of high purity media in trace analysis. Dispensing of metal traces, usually in the low ppb range, or even in the ppt range, depending on the application. The established cleaning process for use in trace analysis is explained in the operating instructions. Can be used as a dispenser for hydrofluoric acid with a platinum-iridium valve spring.
Materials in contact with media
High-purity plastics (PTFE, ETFE, PCTFE, FEP and PFA), sapphire valves, platinum-iridium or tantalum spring material.
Limits of use
Max. vapour pressure 600 mbar; max. viscosity 500 mm²/s; max. temperature +40 °C; max. density 3.8 g/cm³.
Discharge tube without recirculation valve, prevents contamination of the bottle contents
