Plastics in contact with media consist of high-purity materials such as PTFE, ETFE, FEP, and PFA. These materials release virtually no metal ions after appropriate cleaning. The purest sapphire is used for replaceable valves. Platinum-iridium or tantalum valve spring versions can be selected, depending on the dispensed media.

  • Volume range: 1 to 10mL
  • Especially well suited for dispensing high-purity acids, bases and hydrogen peroxide
  • Trace metal content of dispensed liquid is generally in the low ppb range, or, depending on application, even in the ppt range
  • A field-tested cleaning process before use in trace analysis is described in operating manual
  • SafetyPrime™ valve can be removed, if your protocol recommends it.
  • 45mm standard thread (plus included adapters) fits most common lab bottles
  • Valve block can be rotated 360° so that bottle label always faces user for safety
  • Telescoping filling tube adjusts to different bottle sizes
  • Easy disassembly for replacement of the dispensing cartridge
  • Also useful for dispensing HF (Pt-Ir model only) or bromine†
Replaceable dispensing cartridge
  • If piston seal is worn after an extended period of use, the entire dispensing cartridge can easily be replaced without tools by the user
  • Cartridge is fully adjusted at the factory, and delivered with performance certificate
  • No calibration is required after replacement
Serial dispensing
  • For easy serial dispensing, an optional trace analysis flexible discharge tube with textured safety handle (not approved for HF) is available upon request to permit fast and precise dispensing, even into narrow test tubes
  • Full functionality of SafetyPrime recirculation valve and safety discharge system is maintained after installation

† Note: Hydrofluoric acid reacts slightly with sapphire. Therefore a minor increase of the aluminum level may occur.
