These pH electrodes are ideal for biological samples containing proteins.
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 ProtelyteTM reference electrolyte. ProtelyteTM 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.
MinitrodeTM P The small size of this 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).
FoodtrodeTM This sensor is ideal for measuring the pH of samples stored in cold rooms. Select this sensor if your sample is between -10° to +100°C. It has a 12 mm diameter tip.
FlushtrodeTMP If your sample contains between 5 to 85% water, this is the ideal sensor for you. It is good for determining pH of buffer solutions. It has a 12 mm diameter tip.
TiptrodeTM This 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 A7 type connectors. To ensure the most accurate pH measurements, calibrate your electrodes with DURACAL®Buffer Solutions.
