A complete range of patented pH buffer solutions provides never before achieved pH stability. HAMILTON guarantees DURACAL pH buffers to last for five years from the date of manufacture. The pH 9. 1 and pH 10.01 buffers are even stable in air. High buffer capacities enable quick and stable calibrations.

Closed-loop traceability: in contrast with other manufacturers who operate with a hierarchical (top-down) traceability, HAMILTON has developed a new approach featuring “closedloop” traceability. For users of DURACAL pH buffer solutions this means 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 lot manufactured, a representative quantity is measured at DKD. This ensures an external independent verification by an accredited institute.

The DKD issues an official calibration certificate for every DURACAL batch manufactured.
