Buffers

Accurate, stable buffers are critical for the calibration of pH and redox electrodes to achieve accurate measurements, particularly with modern pH meters incorporating GLP functions for recording electrode performance. DURACAL™ pH and Redox Buffer solutions are the buffers you can trust. They offer you many advantages over traditional buffer solutions: guaranteed five year stability, excellent stability of even pH 9.21 in air, see Figure 1, automatic buffer recognition so you use the correct buffer to calibrate. All of this in a unique time saving, money saving dispensing bottle.

Accurate, stable buffers are critical for the calibration of pH and redox electrodes to achieve accurate measurements, particularly with modern pH meters incorporating GLP functions for recording electrode performance. DURACAL™ pH and Redox Buffer solutions are the buffers you can trust. They offer you many advantages over traditional buffer solutions: guaranteed five year stability, excellent stability of even pH 9.21 in air, see Figure 1, automatic buffer recognition so you use the correct buffer to calibrate. All of this in a unique time saving, money saving dispensing bottle.
DURACAL Buffers are guaranteed for 5 years from the date of production. During this time they retain a high buffer capacity for fast, stable calibrations. The pH 7.00 buffer is less sensitive to ions while the pH 9.21 buffer provides stability superior to conventional buffers. See Figure 1 for a comparison of DURACAL™ and conventional buffer stability when subjected to prolonged air exposure.
The unique, easy-to-use, CALPACK™ dispensing bottle allow electrode calibration in the buffer bottle without contamination. In 4 easy steps, calibration is complete, see Figure 2. It’s that simple! No more searching for a suitable container, no more cleaning, no more risk of contamination, and no more wasted buffer from overfilling a container. The composition of DURACAL™ Buffers has been optimized so the temperature function is similar to that of conventional buffers. This guarantees that the automatic buffer recognition of most pH meters can be used without any
problems.
