Porotrode

Porotrode
Beställningsnummer: 6.0235.200

Combined pH electrode for pH measurement / titration of:

  • protein-containing samples (foodstuffs, biological samples)
  • heavily contaminated samples
  • viscous samples

The specially developed capillary diaphragm and the reference electrolyte Porolyte (6.2318.000) enable an optimum performance in samples containing protein. Storage in storage solution.

    Reliable measuring results over long periods of time can be guaranteed only if the pH glass membrane and the diaphragm receive preventive and regular care. Cleaning by etching with toxic chemicals or applying mechanical treatment to the diaphragm is not only complicated and expensive, it also accelerates the ageing of the pH glass electrode.
    The cleaning solution was developed for easy and gentle cleaning of pH glass electrodes. Regular use can considerably prolong their service life.

    This cleaning solution is also part of the pHit kit.
