Dispensette® TA
Dispensette® TA · Trace Analysis
for the dispensing of high-purity chemicals.
  • Plastics in contact with media consist of high-purity materials such as PTFE, ETFE, FEP, and PFA. The purest sapphire is used for replaceable valves. Depending on the application, platinum-iridium or tantalum are available as spring materials.
  • Especially well suited for dispensing acids, bases and hydrogen peroxide. For dispensing HF, we recommend the use of the Dispensette® TA bottle-top dispenser with platinum- iridium valve spring.
  • 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 the operating manual.
  • If contamination of the bottle contents must be avoided, we recommend using the device without the SafetyPrime™ recirculation valve.
  • The 45 mm standard thread plus the included adapters fit most common lab bottles.
  • The valve block can be rotated 360° so that the bottle label always faces the user for safety.
  • Telescoping filling tube adjusts to different bottle sizes
  • Easy disassembly for replacement of the dispensing cartridge

Recommended Application Range

If the piston seal is worn after an extended period of use, the entire dispensing cartridge can easily be replaced without tools by the user. The cartridge is fully adjusted at the factory, and delivered with a performance certificate. No calibration is required after replacement.

For easy serial dispensing, an optional flexible discharge tube with textured safety handle (not approved for HF) permits fast and precise dispensing, even into narrow test tubes. Full functionality of the SafetyPrime™ recirculation valve and the safety discharge system is maintained after installation.

  

 
     

* Hydrofluoric acid reacts slightly with sapphire resulting in mildly elevated aluminum values. To reduce these values we recommend discarding 3-5 dispensings of 2 ml each before performing the analysis. 

The above recommendations reflect testing completed prior to publication. Always follow instructions in the operating manual of the instrument as well as the reagent manufacturer‘s specifications.
