Protein Resistant pH Electrodes
These pH electrodes are ideal for biological samples containing proteins.
- Ideal for determining pH in samples that contain protein
- Faster response times than traditional pH electrodes
- More accurate than traditional pH electrodes
- Longer electrode life and more economical
- Five styles available to meet most application needs
- Operational pH range from 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.
These pH Electrodes are supplied individually and have A7 type connectors. To ensure the most accurate pH measurements, calibrate your electrodes with DURACAL®Buffer Solutions.
pHamp pH Preamplifier
This rugged preamplifier is encapsulated within an epoxy filled stainless steel enclosure and uses BNC-style input and output connections. Powered from a lithium battery, the expected life is a minimum of 5 years.
