Dispensette® TA - Bottle-Top Dispenser for Trace Analysis, BRAND

The new product range of the bottle-top dispenser Dispensette® covers a broad variety of application requirements.

The new bottle-top dispenser Dispensette® TA provides outstanding performance for precise-volume dispensing of high-purity media for trace analysis, for example acids (e.g. concentrated nitric acid), alkali (e.g. sodium hydroxide) and hydrogen peroxide. The device is also suitable for dispensing hydrofluoric acid (HF) and bromine.

The product highlights at a glance:

  • Plastics in contact with media consist of high-purity materials such as PTFE, ETFE, FEP, and PFA, purest Al2O3 sapphire, and, depending on the application, platinum-iridium or tantalum.
  • Fast setting of the desired dispensing volume
  • Replaceable dispensing cartridge, easy to replace by the user when the piston seal is worn
  • The spare dispensing cartridge is supplied factory-adjusted with quality certificate. No calibration is required after replacement
  • Suitable for media with up to: vapor pressure of max. 600 mbar, kinematic viscosity up to 500 mm2/s, temperature max. 40°C, density max. 3.8 g/cm3

Scope of delivery:

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.
