DURACAL pH Buffers

DURACAL pH Buffers

A complete range of patented stable pH buffer solutions from pH 1.09 to 12.00. HAMILTON guarantees DURACAL pH buffers to last for five years from the date of manufacture. The pH 9.21 and pH 10.1 buffers are even stable in air. High buffer capacities enable quick, stable calibrations.

Closed-loop traceability: In contrast with other manufacturers, who operate using only hierarchical (top-down) traceability, HAMILTON has developed a new approach featuring “closed-loop” traceability for the values 4.01, 7.00, 9.21 and 10.01. For users of DURACAL pH buffer solutions, this ensures a unique level of reliability.

Top-down traceability: With HAMILTON, the pH value of the DURACAL buffer is determined by a comparison with two secondary reference solutions. Bottom-up traceability: From each batch manufactured, a representative quantity is measured at DKD. This ensures an external, independent verification by an accredited institute. DKD issues an official calibration certificate for the corresponding DURACAL production batch.
