Hamilton Company offers one of the most comprehensive selections of laboratory pH sensors and accessories in the industry

• Combination electrodes
• Potential measured against reference electrode

Each product is characterized by high quality, long life and extremely accurate measurements. Hamilton's specially designed line of laboratory electrodes offer many advantages. All electrodes are printed with an indelible serial number. Individual test certificates with measured millivolt values. Indelible labels ensures long-term readability. Ergonomic electrode head. Proven electrolyte sealing system. High-quality seal between electrode head and cable (IP 68). Integrated, captive seal at the electrode refilling plug. Blue inner buffer provides visual indication of contact with the pH membrane. Watering cap with screw lock for storage. Easy removal of the watering cap by means of the screw lock. Secure sealing of the watering cap. No spilling of electrolyte when removing the watering cap.

General Use sensors are used for many different applications and must show excellent accuracy, provide fast readings, and endure long periods without use. Choose from refillable glass-body pH electrodes to robust, maintenance-free plastic shaft electrodes. Special Use Electrodes are for special laboratory applications such as microbiological samples, serum, flat surfaces, small volumes, and those containing fats and proteins.

Hamilton laboratory pH sensor types include

Polilyte™ Lab - Maintenance free with the accuracy and stability required by laboratory electrodes. Thanks to the Single Pore™ design, clogging of the diaphragm is virtually impossible. Biotrode™ - Combination electrode especially made for measurements in very small volumes, such as microtiter plates, by requiring an immersion depth of only 7 mm. It is also ideally suited for solutions containing protein, as Protelyte™ electrolyte that prevents clogging of the diaphragm. Spintrode™ - Combination electrode especially made for measurements in very small volumes, such as NMR tubes, that only requires an immersion depth of 7 mm. Flatrode™ - Features a true flat membrane for surface measurements such as paper or agar plates. The robust plastic shaft with a ring diaphragm guarantees quick response though enhanced contact between the sample and reference.
