must be followed (do not swallow, do not taste, always wear gloves, etc.).
The ampules have a blue dot colored breaking ring. The ampule can be opened manually by breaking it off at this
point. Follow all safety precautions for the handling of glass (splintering, breakage, etc.).
Buffer Solution and Gelatin Solution (Working Solution)
The Buffer Solution and Gelatin Solution are hazardous materials according to EC Directive 67/548/EEC.
Information of safety and handling can be found in the attached safety data sheets.
The shelf life of a fresh Working Solution (a vial of Buffer Solution plus 20 drops of Gelatin Solution), is maximum
of 14 days when kept in a sealed opaque vessel and stored at 25-46.4°F, ( 2˚C to 8˚C). Working Solution (which
contains silver chloride) that is to be used for measuring purposes should be used as soon as possible since it can
react photochemically with light (reduction of the precipitated silver chloride into elementary silver). It is
recommended that a new working solution is prepared for each measurement series. The on-board stability of
the working solution is 24 hours at room temperature.
