Less Volume Samples

  • The volume of sample must be enough to cover the glass membrane and liquid junction of the pH electrode during measurement.
  • ToupH electrodes are constructed with thick glass membrane,  that is highly resistant to impact and chemicals.
  • Long pH electrodes, come in 3mm and 8mm diameters, are suitable for test tubes and tall containers while micro pH electrodes with 3mm diameter are perfect for small tubes and trace amount of samples.
