Dispensatori TA² Tracce Analisys, a volume variabile

Dispensatori TA² Tracce Analisys, a volume variabile

A specially developed and proven cleaning process to be done before use results in a reduced release of trace metal ions to the low ppb range or, depending on the application, even the ppt range.
  • The parts that are in contact with media are made of various fluoroplastics (e. g. ETFE, FEP, PFA, PTFE, PCTFE), Al2O3-sapphire, platinum-iridium or tantalum (depending on model).
  • Exchange valve spring: a platinum-iridium or tantalum valve spring can be used, depending on the application.
  • A field-tested cleaning process to employ before use in trace analysis is described in the instruction manual.
  • Outstanding chemical resistance, especially to aggressive media such as highly concentrated acids and alkalis, hydrogen peroxide, hydrofluoric acid and bromine.
  • Modular structure for simply dismantling while cleaning and for replacing the dispensing cartrige.
  • Quick, easy and precise volume adjustment due to interior scalloped track and practical screw mechanism.
  • With screwable discharge valve.
