Protein Resistant pH Electrodes

Measuring the pH of biological samples containing proteins is difficult. Proteins in solution can combine with silver ions from the electrolyte to clog the pH electrode diaphragm. This leads to long response times, inaccurate pH measurements, and eventually discarded electrodes. These protein resistant electrodes are designed for rapid, accurate, and reproducible pH measurements of protein containing solutions.
Unique to these pH electrodes is the specially formulated Protelyte™ reference electrolyte. Protelyte™ electrolyte prevents the precipitation of proteins on the electrode diaphragm. You get faster, more accurate, reproducible pH measurements of your samples. Select from five specialized electrodes. The best electrode for you depends upon your applications, physical size limitations, and temperature range. Each has a pH range of 2 to 11.

Measuring the pH of biological samples containing proteins is difficult. Proteins in solution can combine with silver ions from the electrolyte to clog the pH electrode diaphragm. This leads to long response times, inaccurate pH measurements, and eventually discarded electrodes. These protein resistant electrodes are designed for rapid, accurate, and reproducible pH measurements of protein containing solutions.
Unique to these pH electrodes is the specially formulated Protelyte™ reference electrolyte. Protelyte™ electrolyte prevents the precipitation of proteins on the electrode diaphragm. You get faster, more accurate, reproducible pH measurements of your samples. Select from five specialized electrodes. The best electrode for you depends upon your applications, physical size limitations, and temperature range. Each has a pH range of 2 to 11. The small size of the Minitrode™ P sensor makes it ideal for pH measurement of sample in microplates and microcentrifuge tubes. The sensor tip is 3 mm diameter with a usable length of 100 mm (3.9 inches). Use the SPINTRODE™ to determine the pH of samples in NMR tubes. The 3 mm diameter, 180 mm (7 inch) long sensor allows you to determine the pH without transferring the sample from the NMR tube. The Freezetrode™ sensor is ideal for measuring the pH of samples stored in cold rooms. Select this sensor if your sample is between -20 to +80C. It has a 12 mm diameter tip. If your sample contains between 5 to 85% water, the Flushtrode™ P is the ideal sensor for you. It is good for determining pH of buffer solutions. It has a 12 mm diameter tip. The Tiptrode™ pH sensor was designed for pH measurements in applications requiring penetration of solid and semi-solid materials including: foods, gelatinous materials, and viscous buffers. It has a 6 mm tip.
These pH Electrodes are supplied individually and have S7 type connectors. To ensure the most accurate pH measurements, calibrate your electrodes with DURACAL™ Buffer Solutions, see next page for more information.
