Brochure: Duracal pH Buffers

A complete range of patented buffer solutions provides never before achieved pH stability. Hamilton guarantees DURACAL pH buffers for 5 years after the date of manufacture. The pH 9.21 and pH 10.01 buffers are even stable in air. High buffering capacity provides rapid, stable calibration. Preservatives are added to prevent microbial and mold growth. Closed Loop Traceability: Unlike other manufacturers where only a top-down traceability is applied, Hamilton is working with a circular or closed loop traceability.
