Elektrode pH Flatrode

Flatrode pH Electrode - Flat Ring Membrane Electrode for Surface Measurements, Range 0-14 pH, 0-60 °C

The Flatrode pH electrode is a glass electrode with a true flat ring membrane designed to measure pH on flat and semi-solid surfaces – paper, agar plates and even leather. The flat membrane adheres directly to the test surface and increases the contact of the sample with the electrode, thanks to which the electrode achieves a short reaction time where immersion of a classic spherical electrode is impossible. The design is rounded off by a heavy-duty plastic handle, an Everef reference chip with Skylite-CL electrolyte and a bore diaphragm, while the S7 connector head ensures compatibility with standard pH meters.

Application of the Flatrode pH Electrode

The Flatrode pH electrode is suitable for applications where measurement requires contact with a flat or semi-solid surface rather than immersion in a solution. The flat membrane allows you to read the pH of paper and cardboard (control of pulp and paper production), the surface of agar-bed plates in microbiology, and the surface of the skin in dermatological and cosmetic tests. The electrode is also used in food and materials quality control laboratories where the sample is in the form of a sheet, gel or soft solid that cannot be measured with a standard immersion electrode.

Other electrodes and pH sensors in Danlab's offer: Biotrode pH Electrode, Double Pore pH Electrode, Flushtrode pH Electrode, Foodtrode pH Electrode, SenTix Series pH Electrode and InPro Series pH Electrode.

Advantages of the Flatrode pH Electrode

• Flat annular membrane: allows pH measurement directly on the surface of paper, agar plates and leather
• Increased sample-membrane contact: reduces response time and readout stabilization
• Everef Reference System with Skylite-CL Electrolyte: Stable Reference Potential for Surface Measurements
• Hole diaphragm: reduces the risk of clogging in dense and semi-solid samples
• Plastic stem: mechanical resistance higher than that of all-glass electrodes
• S7 connector: compatible with standard laboratory pH meters
• Wide measuring range of 0-14 pH at 0-60 °C
