Solitrode HF

Solitrode HF
Beställningsnummer: 6.0223.100

Combined pH electrode for titrations/measurements in HF-containing samples. This electrode is mechanically resistant thanks to the robust/unbreakable plastic shaft made of polypropylene and impact protection for the glass membrane.
Reference electrolyte: c(KCl) = 3 mol/L, 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.
