Accurate and stable buffers for pH and redox electrode calibration.
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 Buffers are buffer solutions you can trust. They offer you many advantages over traditional buffer solutions including guaranteed stability (excellent stability of even pH 9.21 in air) and automatic buffer recognition so you use the correct buffer to calibrate. All of this in a unique time and money saving dispenser bottle.
The unique, easy-to-use, CALPACKTM dispensing bottle allows electrode calibration in the buffer bottle without contamination. In 4 easy steps, calibration is complete.
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.
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.
