1 Dispensette® TA - bottle-top dispenser for trace analysis

The well-known product range of the bottle-top dispenser Dispensette® provides dispensing task equipment for a great variety of applications.

The Dispensette® TA is ideal for high-precision dispensing of high-purity media for trace analysis. With Pt-Ir valve spring suitable for dispensing hydrofluoric acid.

General properties of the bottle-top dispenser Dispensette®TA

  • 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.
  • A field-tested cleaning process before use in trace analysis is described in the operating manual.
  • To avoid contamination of the content of the bottle, we recommend using the unit without the SafetyPrimeTM recirculation valve.
  • GL45 thread and the adapters comprised in the delivery match most commonly used test tubes.
  • Bottle label always visible thanks to 360° rotating valve block
  • Telescopic suction tube can be set for different bottle heights
  • Easy to disassemble for replacement of the dispensing cartridge

1) Adjusted to "Ex". Error limits according DIN EN ISO 8655-5 related to the nominal capacity (= maximum volume) indicated on the instrument, obtained when instrument and distilled water are equilibrated at uniform temperature (20 °C) and with uniform and smooth dispensing. The results are significantly below the error limits specified in DIN EN ISO 8655-6. Conformity certified according to DIN 12 600. R = Correctness, VK = Variation coefficient.
